Construction material suppliers and manufacturers are developing various types of products and materials for the current building industry. The building facade, a cladding system, is the crucial element of any residential or commercial facility that exterior designers and architects focus on for creating attractive and aesthetic designs for their clients. Thus, manufacturers provide various cladding systems with unique characteristics. Due to the importance of energy in the current era, metal wall cladding systems have become the most famous building facade materials in the market. Metal wall claddings come with various materials, including steel, copper, CORTEN, aluminum, etc. However, aluminum metal wall claddings are the dominant products in this industry, including aluminum plate systems, ACM panels or aluminum composite panels, and aluminum siding. However, most people will be confused when choosing Aluminum siding or ACM panels.

Moreover, manufacturers create walling systems with aluminum in two main categories: aluminum siding and aluminum composite panels. It is essential to mention that some other products such as aluminum longboard sidings and aluminum wood sidings are practical and are combined with traditional materials for people who prefer classic looks for their buildings. This article will help you choose between aluminum sidings or ACM panels for your next project.

What is Aluminum Composite Panel (ACP or ACM panel)?

The first Aluminum Composite Panels or ACM panels were produced and invented in the 1960s by various companies. ACM panel cladding systems consist of two exterior layers of aluminum sheets and one core substance. The traditional aluminum composite panels did not have fire-resistant characteristics due to the highly flammable polyethylene core. However, after the growth of technology, ACM panels manufacturers managed to use FR (fire-retardant) core for their new materials, making them fire safety construction materials.

There are generally three types of facilities in the building industry: type A that features more than four floors, type B has three floors, and type C consists of less than two levels. ACM panels are practical for all types, but they are most efficient for classes B and C. Aluminum composite panels (ACM panels) are available in various colors and sizes. The standard dimensions of ACM panels in Canada are 3mm, 4mm, and 6mm.

ACP Cladding Materials Cons

  • In extremely harsh weather conditions, ACP materials are susceptive to dent.
  • While installing ACM panels, the contractor and the builders should seal the cladding boards properly and make them waterproof.

What is Aluminum Siding?

Aluminum siding cladding is a construction material that has been used for cladding systems for decades. These functional materials are the perfect choice for locations that have mid to low temperatures, such as Canada. The primary material in aluminum siding claddings has remained the same from their first day of production. However, construction material suppliers started using various cutting and new fabrication machines for cutting, shaping, bending, and installing. These sheet metals are developed through a process that has less impact on the environment than other traditional cladding systems. Manufacturers roll pure aluminum with special devices and store them or send them to the construction site. To have a vision about how long these materials can last, you can easily find that the existing buildings in Canada have had their siding applied since the 1970s.

Pros of Aluminum Siding Materials

  • Aluminum siding materials are cost-effective materials and are highly affordable.
  • These construction materials are 100% recyclable, and they will not end up in a landfill.
  • Metal wall claddings with aluminum are energy efficient and great insulators during cold and hot seasons.
  • They are considered low maintenance materials, and unlike other materials, they do not require regular cleaning.
  • Aluminum siding panels are durable and can last for a long time.

Aluminum Siding Cons

  • As aluminum is a soft metal, sidings made from this substance are susceptible to dents and scratches.
  • These aluminum cladding systems consist of painting coats worn out after years of rainwater and sunlight exposure.
  • Current architects prefer ACM panels to aluminum sidings because traditional sidings are out of style, and creating contemporary designs will be hard.

ACM Panels Installation Guide with Details

Aluminum Cladding Installation Process for Commercial Building

Building a residential facility, an office, or a board for advertisement can sometimes be a challenging and daunting task due to the complexity involved in the installation process. Developing a structure from 0 to 100 requires having a precise plan and schedule, but it also needs to be cost-effective and enjoyable. The essential part for building construction or an advertisement board mostly depends on various elements, including the contractor, project budget, and materials used for the purpose. This is why modern building materials come to the picture, including ACM panels.

Some factors for building a new office or home may not be in the customer’s hands. However, choosing and installing suitable building materials is unquestionably a choice. Choosing and buying construction materials for a custom facility or commercial building has become more manageable after manufacturers started developing aluminum composite material panels (ACM panels). However, before utilizing them in your next project, you will need to know what ACM panels or ACP materials are and how ACM panel installation should be done.

What are Aluminum Composite Materials (ACM)?

ACM panels manufacturers developed these functional materials with beneficial characteristics making the head product in construction and architecture. Compared to other construction materials, Aluminum composite panel (ACP) and supplies reveal their advantages. By looking at some high-quality ACM panels characteristics, including durability, rigidness, flexibility, and lightweight, the difference between other traditional cladding materials is evident. Additionally, it is easy to recycle ACM panels for other projects. Furthermore, the numerous applications of ACM panels make them the perfect choice for architects and builders.

Aluminum composite panels feature two primary layers of aluminum sheets and a core substance placed between other layers. Although ACP materials have not raised severe issues after their development, the core materials have been a leading obstacle. In other words, old composite panels didn’t feature non-combustible core material. However, ACM panels manufacturers managed to find and utilize FR (fire-retardant) substances and solve the issue once and for all. ACM manufacturers changed the polystyrene to a mineral-filled sense, and these materials gained approval from building regulations for safety. Thus, it is essential to check if the core is made from FR materials before ACM panels installation.

ACM Panels Installation Process

Although ACM panels are functional for various applications, including transportation, signage, industry, and more, they are primarily used as exterior building metal cladding systems and interior decoration materials. ACM panels installation involves different steps depending on the client’s demands. Thus, it is better to contact the ACM panel manufacturers and gather the details when buying aluminum composite panels.

Aluminum Composite Panel Installation Steps:

  • Measurement: The first step of installing any building material is to measure the dimensions and size of the demanding product. It is essential to do the measurements precisely. Even the slightest mistakes can cause money and time loss.
  • Fabricate: After determining the accurate size of the aluminum composite panels, the board provider should fabricate them in the demanding dimensions. ACM panels manufacturers utilize various professional tools for cutting, folding, bending, and drilling their materials. Installing supporters and fasteners can also take place in this step.
  • Waterproofing: Another essential step of ACM panels installation is waterproofing. The weather barrier which should protect the structure needs to be installed before applying the aluminum composite claddings. In this step, a primer should be applied to the framings, and then the barrier is utilized to seal the cladding materials.
  • Applying the Mounting System: Builders use a mounting system to ensure the straight alignment of ACM cladding panels. After applying the mounting system, the cladding boards are installed in a fixed order. The order depends on different factors, such as the priority of shaped areas and corners.
  • Installing ACM Panels: In the final stage, ACM panels should be installed on the mounting. It is better to ensure that the primary profiles (clips) are connected to the aluminum composite panels. Then, the installer must screw the boards to the wall. After ACM panels installation, there will be a gap between the boards. Most ACM manufacturers utilize a strip for matching and hiding these gaps. Other supporters, such as shims and additional clips, are utilized in the final stage for leveling and attaching the cladding materials.

ACM Panels Installation Guide for Outdoor Application and Purpose

ACM panels outdoor applications require different installation methods. All methods require accuracy and precision. Due to the wind loads in the back of the composite panels, it is crucial to install weather resistance barriers. As told earlier, fire retardant core also represents a significant role in ACM panels cladding systems.

  • The primary consideration for aluminum composite cladding panels is preparations. Choosing a fixed direction is essential to paint ACM panels. (Arrow direction on the protective film)
  • For preventing damages and scratches on the boards, it is better to roll, cut or drill the product from the back.
  • Developing a sketch for ACM panels installation is essential since some sections such as windows and doors need to be installed before other portions.
  • Builders should install the first panel in areas such as corners.
  • Permanently remove the protective films as each section’s installation is done.
  • Aluminum composite installation for exterior wall cladding is crucial. The ACM panels should be sealed in the correct order. Otherwise, water leakage will possibly be an issue during rainy weather.

Aluminum Composite Panel (ACP) Compared to other Building Materials

Aluminum Composite Panel (ACP)

Currently, there are a wide array of construction materials available for architects, constructors, and builders. Selecting and buying suitable building material for the demanding project depends on numerous factors, including price, versatility, durability, finishes, and purpose. Thus, clients and architects must choose the most suitable construction materials for their projects and applications. One of these materials widely used in modern and industrial cities such as Toronto is Aluminum Composite Panel (ACP), also known as ACM panels claddings and roofing systems. In the current industry, Aluminum composite panels are utilized not only for construction but for other applications in different industries.

Aluminum Composite Panel (ACP) Structure

ACM panels are also referred to as aluminum composite sheets, sandwich panels, and ACM materials. As told, these modern products are widely used in construction projects and other industries. The thing that made ACM panels unique and different compared to other building materials is their structural properties which provide outstanding quality and functionality among other particles.

The importance of each construction material is summarized in its structure. In other words, if the architect or customer wants to know whether the building material features the suitable quality and characteristics for the demanding project, they will need to learn about its structure and form.

Aluminum Composite Panel (ACP) Core Material

The Aluminum Composite Panel (ACP) features a three-layered structure, including two sheets of aluminum and one fire-retardant core substance. This central core of ACP materials is the essential part of these building materials. However, at first, some issues started when the fire behavior of these construction materials went under question. The early aluminum composite panel featured a PE core substance that is sustainable to fire and spreads quickly. This problem is solved with various solutions. However, some countries abandoned PE cores, and others allow builders to utilize them for low-rise buildings.

Though the former systems seemed to be reliable, modern manufacturers provided better resolutions for aluminum composite panels. They typically utilize fire-retardant (FR) substances to make ACM panels safer than other construction materials. These solutions are perfect for exterior applications, including using ACM panels for cladding systems where safety plays a massive role in the building’s facade. The FR core materials can be varied depending on the local building codes and requirements. However, the common fire-retardant substances are mineral materials and honeycomb, which manufacturers utilize in their aluminum composite panels.

Coating Materials on ACM Panels or ACP Finishes

Although the substance used in the structure’s core is of great importance in an Aluminum Composite Panel (ACP), coating materials on ACM panels are also essential and affect the overall quality. Generally, manufacturers utilize two types of coating for these construction materials. The first one is PE finish, which is the same as for PE core. Thus, this can cause issues similar to the core material. However, it is possible to utilize this coating as the leading material on the surface for interior applications. Some of the internal usages of the PE coating include perforated and decorative panels, wall partitioning, and false ceiling.

On the other hand, experts recommend using coating materials such as PVDF or Nano aluminum composite panels for cladding systems and other external applications. These coating types provide better durability and quality and offer better safety and resistance against fire. Additionally, Nanocomposite panels are anti-dirt and water-retardant. Thus, they will require lower maintenance, and cleaning them is very straightforward.

Best Qualities of ACM Panels

The aluminum composite panel (ACP) has advantageous characteristics, qualities, and features, making it the perfect material for building cladding systems and facades. Due to its structural components and properties, ACP material is one of Canada’s most used building materials. The followings are the primary and beneficial characteristics of aluminum composite panels (ACP).

  • Flexibility, Versatility and Durability: One of the unique characteristics of an aluminum composite panel (ACP) is its flexibility, versatility and durability. Most construction materials do not feature three of these properties at once. It is accessible to fabricate and installs ACM panels, and they will last more than 30 years if maintained properly. Due to the versatility of ACP materials, manufacturers can produce various cladding products with different styles and shapes, allowing architects to create limitless designs for their clients.
  • Chemical and Water Resistance: ACM panels are manufactured in a way to withstand harsh weather conditions. These building materials are water and chemical resistant, and they can be utilized in different portions of a facility. This advantage of ACP materials makes them the perfect cladding materials for locations with high humidity and temperature change. However, if these panel systems are not installed properly, they can have leakage. Thus, it is essential to follow a rainscreen installing instructions precisely.
  • Lightweight Material: Most clients should pay considerable money to labor costs when constructing a new building. However, due to the lightweight characteristic of an aluminum composite panel (ACP), it is easy to install these building materials for cladding systems resulting in lower labor costs.
  • Aesthetics: Architects prefer using metal wall cladding systems, including ACM panels, which are the perfect materials for building facades, as they are modern, flat, and sleek. Most manufacturers create ACP materials in different color finishes and textures. Even ACM panels with wood pattern finishes are available for clients who prefer to have a mixture of contemporary and classic designs for their building’s cladding system.

Why do Architects Prefer Using Metal Wall Cladding?

Metal Wall Cladding

Metal Wall Cladding Systems have proven their capabilities in the construction and building materials industry. These building facade products hugged the complexities of architects for a long time. This is because building designers appreciate metal wall cladding systems for their flexibility and wide range of finishes. However, due to these building facade products’ considerable strength, architects are challenged to specify them for the suitable envelope. The possibilities for different designs, methods of installation, forms, and fabrication procedures are limitless. Additionally, metal wall claddings are manufactured with various materials, making them available in different forms, including ACM panels or Aluminum composite panels, aluminum siding wall claddings, stainless steel metal facades, etc. Various factors allow designers and architects to create a modern appearance for contemporary buildings by utilizing metal wall cladding.

Metal Wall Cladding Systems

Industrial metal panels or materials are most suitable for the rain screen cladding systems, where the primary mission is to protect the facility from external damaging elements and a striking exterior finish. Due to the beneficial physical properties of ACM panels and other metal wall claddings, they can be bent, cut, fabricated, installed, and attached to the building’s structure in different methods. Each method provides unique benefits in terms of aesthetics and functionality. The following are some of the methods architects and designers prefer to use for metal wall cladding systems.

  • Standing Seam: This system is one of the famous building claddings in the construction industry, which features strong folded attachments between each of their boards. These boards are specially produced to allow architects to create modern exterior designs and building facades. The standing seam systems come with various materials, including aluminum composite materials, steel, galvanized steel, zinc, and CORTEN steel.
  • Snap-Lock Systems: The snap-lock cladding system is the more straightforward alternative to the design above which is used for displaying ribbed profile and do not require special tools and equipment for the installation. The design is uniquely done for allowing boards to snap together with an easy installation process.
  • ACM panels: Another famous and practical metal wall cladding systems are ACM panels or ACP materials. These building materials consist of two sheets of aluminum and one fire-retard core substance. Due to the various benefits of ACM panels, architects utilize them in most modern commercial buildings.
  • Interlocking System: The only system which offers a smoother and dramatic appearance is the interlocking system which consists of an express joint. This type of metal wall cladding system has various widths and involves horizontal, vertical and diagonal installing processes.
  • Cassette Panels for Buildings: Cassette panels are the best choice when creating a building facade with large cladding areas. One of the systems, which is known as the open-joint panel system, is appropriate for being used with panels that are large in length. The manufacturers utilize various bending machines to bend the cassette panels and fix them to an aluminum framework with invisible clips. The flat and contemporary look of these metal wall cladding systems satisfies almost all current architectural requirements for commercial and residential constructions.
  • Custom Metal Wall Claddings: Manufacturers provide custom metal wall cladding systems for projects that require unique designs for the building’s facade. They develop new strategies by altering an existing cladding and create something new. However, demanding custom wall products can increase the overall cost of the project.

Performance Factors

Despite the various metal wall systems designs and finishes, the main reason for using these building facade products is their functional characteristics and performance factors. These cladding systems protect the building from different damaging elements and help the facility to survive for decades. Additionally, other practical performance factors are making these metal wall cladding suitable for the current construction industry.

  • Durability: Metal wall claddings are often more durable than other building materials such as Wood sidings which are also perfect materials that architects admire. Architects and designers determine their building’s requirements, and manufacturers create protective coating and utilize the most durable substance equivalent to the location’s conditions. For instance, ACM panels can last for decades without any damages if appropriately maintained.
  • Fire Resistance: Current building codes and standards demand fire-resistant construction designs. ACM panels (aluminum composite panels) are highly resistant to fire due to the fire-retardant core manufacturers utilize for producing them.
  • Acoustic Property: Most metal wall cladding systems, including ACM panels, are perfect insulation for the building. These materials damp the sound vibration by sending it down to earth through the structure of the facility. However, these building facade systems have limited sound insulating properties between the internal and external areas. Thus, the metal supplier should calculate the wall ratings, factoring in the weighted reduction in sound or transmission classification of the exterior panels.

How Much do Various Types of Metal Cladding Systems for Building Cost?

Metal Cladding Systems Cost

The cladding system of the buildings is the primary factor making the city look brilliant and different from other cities. Architects focus on creating aesthetic building facades with varying wall materials to provide eye-catching sight for the facility for pedestrians walking past the area and the occupants. Moreover, manufacturers produce different types of metal cladding systems in a wide array of finishes and styles to help architects and builders provide structural support, attractiveness, and increase energy efficiency for the buildings across the country. Thus, over the past few years, different types of metal cladding systems, in particular, have been gaining popularity in Canada and the USA.

The durability of traditional brick claddings are well-regarded, but they do not offer considerable flexibility and room for customization as metal cladding materials do. Metal panel systems can be fabricated or cut into a variety of modern designs and shapes. Additionally, these contemporary building materials are easy to paint and can add extra beauty to their appearance.

The current advancement in facade paneling systems and application techniques has brought rain-screen wall products into the construction industry. These practical cladding systems are created with extra layers of metal sheathing featuring waterproof characteristics and empty air space pockets between the panels and the interior wall system. The beneficial properties of rainscreen systems made them the perfect solution for keeping the moisture away from the internal structure, allowing the facility to dry quickly and maintain its finish and beauty during heavy downpours.

Types of Metal Cladding Systems and Their Cost

Currently, metal cladding systems for buildings come in a wide range of materials, including Aluminum Composites, Aluminum, Zinc, Copper, Steel, Galvanized Steel, etc. Landlords and homeowners decide the materials depending on the project’s safety, energy efficiency, and aesthetics. However, the cost for different types of metal cladding systems will primarily affect the choice of the building’s facade. Each of the sheet metal panels for the exterior projects features unique characteristics, styles, and costs. Thus, knowing their difference will help anyone to choose the most suitable material for the new or renewal projects for both private and commercial facilities.

Aluminum Composite Panels & Flat Aluminum Sidings

Due to the beneficial physical properties of Aluminum itself, manufacturers use the material for developing various building materials, including cladding systems for the industry. Aluminum cladding products lines the external systems of over 60% of the commercial and industrial construction projects.

The products made from Aluminum are incredibly lightweight, making aluminum sidings easy to fabricate and install for the project. Another beneficial characteristic of aluminum sidings and ACM panels (aluminum composite panels) is that they are corrosion resistant and immune to rusting. These materials form a dense oxide layer when exposed to humidity and air, providing a natural coating against rain and moisture. Aluminum building materials often last about 40 years if maintained properly. Thus, they manage to be more costly than other cladding systems. However, higher-quality ACM panels having fire-resistant cores can be pricier. The price range for flat aluminum sidings is 4$-10$, and ACM panels are 15$-30$ per sq. ft.

Zinc Metal Cladding Systems

Zin metal cladding systems offer a unique look to any building’s facade, and, as such, the exterior products are slowly gaining popularity among architects. Like aluminum cladding materials, zinc generates an oxide layer that protects the facility against external elements, lasting for up to 100 years. These building materials are also entirely recyclable, making them environmentally friendly products. Due to the unique characteristics of zinc, this substance is more expensive than ACM panels and aluminum sidings. However, they are not as high-quality as aluminum composite panels. The price for flat metal panels of zinc is about 8$-16$, and the cladding systems metal panels cost varies from 22$ to 35$ depending on the dimensions.

Copper Building Facade

Copper panel systems for building facades do not require treatment artificially for preserving their surface from corrosion and rust. These metal cladding systems form a beautiful greenish patina on their own over time which designers appreciate in their projects. Copper materials are considered self-maintaining products as the produced oxide layer covers scratches and other forms of occurred damages. However, installing these metal cladding systems has challenges, and finding an experienced installer may be an issue. Due to the aesthetic qualities of these metal claddings, copper exterior panels are the most expensive products for buildings facades. The price for flat sheet copper is between 10 to 15 Canadian dollars, and the panel’s cost range is 25 to 40 dollars.

Steel and Galvanized Steel Metal Cladding Systems

Steel and Galvanized Steel metal cladding systems are generally the most affordable building facade materials. These cladding products offer an admirable life span of around 32-37 years. However, this substance is considered less durable and flexible compared to ACM panels and aluminum cladding systems. The price of steel panels is generally around 12 to 18 dollars.

What are Nano Aluminum Composite Panels?

Nano aluminum composite panels

Nano aluminum composite panels (ACM panels) are among the newest building materials available in the market, with various advantages. Currently, nanotechnology is creating an industrial revolution noticeable in all aspects of the modern life system. Manufacturers started applying this technology to aluminum composite panels and other construction materials to solve their drawbacks and grow their usage in current architectural projects. The nano-aluminum composite panel features all the previous advantages of the ACM panel, such as anti-scaling, durability, functionality, anti-corrosion, etc.

Nano Aluminum Composite Panels Applications

The traditional aluminum composite panels (ACM panels) are still one of the materials that are commonly used for various structures, products, and building claddings. The construction industry highly welcomes materials such as ACP materials due to their flexibility, versatility, lightweight, and other beneficial characteristics. However, constructions with aluminum composite panel cladding systems face numerous limitations and sensitivities. Cleaning and maintaining the building’s facade is an essential task for both low-rise and high-rise facilities. Thus, the building facade and its clean appearance involve maintenance and the facility’s value as a whole. Moreover, this becomes more crucial for larger and polluted cities.

Nano ACM panels have come to solve the cleaning and maintaining problem. The technology allows cladding systems to clean the aluminum surfaces of the facade on their own without requiring any particular chemical or unique methods.

How Nanotech Works in ACM Cladding Systems

The water droplets on the plant leaves or the ones on a greasy surface are generally spherical, and they are always separated from the surface. This natural event means that the surface is probably dry, and water molecules are attached to form the spheres. This happens due to the physical properties of any substance. Thus, science has divided surfaces into two general classifications, which are hydrophobic and hydrophilic.

The hydrophilicity of a substance’s surface means that the molecules of a particular amount of water tend to depress the area. Thus, water molecules form a narrow-angle or say the droplets’ height is low. In contrast with hydrophilicity, water particles on a hydrophobic surface tend to bond to each other rather than the material. In this case, droplets form a prominent sphere with a broader angle, and the height of the particular amount of water is higher. Additionally, hydrophilic surfaces feature high energy, and in contrast, hydrophobic substances have low energy surfaces. However, with the knowledge of nanotechnology, the physical properties of any surface can be transformed into a selective character. Thus, with the growth of technology, it is possible to create hydrophilic surfaces and change their properties.

Textured surfaces made in another nanoscale feature a greater distance between the air and molecules. This can cause hydrophilicity decrement on the surface, and water droplets will stick to more together than the desired surface. The same can happen with nano aluminum composite panels as water drops do not spread on the surface of the ACM panel and stick to each other. As water drops move on the cladding system, they will absorb the dust or strain and pass through the building facade. Thus, the nano aluminum composite panel’s surface gets cleaned thoroughly without extra cleaning chemicals applied. Additionally, the nano-coating existing on these cladding systems makes it difficult for the dirt and dust to adhere to the ACP surface, resulting in solid stains on the building facade execution.

It is essential to mention that Aluminum composite panels are low maintenance materials naturally, and even with nanotechnology, it is possible to clean them with detergents and cleaning tools. Aluminum sidings and ACM panels cladding systems do not require special equipment for cleaning. The crucial thing about nano cladding materials is that it makes the cleaning process much easier for high-rise buildings.

Advantages of Nano Aluminum Composite Panels

As nano aluminum composite panels have auto cleaning, they bring essential benefits for the building’s owner, which are as followed:

  • Homeowners can save money and energy by using nan ACM panels.
  • The building’s facade will last longer than other cladding materials.
  • The construction and its facade maintain its appearance, resulting in preserving the building’s value, prestige, and overall status.

Like any other composite material, Nano ACM panels consist of various layers, including the core or central layer, the front, rear cladding sections, and finally, the coating surfaces. The modern tech coating is applied to the last layer of the products. The final layer serves the cladding systems as a protector against different elements, including:

  • Urban pollution
  • Oil
  • Wearing over time
  • Sun rays
  • Harsh weather conditions
  • Acid rains
  • Alkaline substances

Why ACM panels are more expensive than other Cladding Materials?

ACM panels

Exterior cladding systems for new construction and renovation projects have become a must-have architectural element for commercial or residential facilities. In contrast with traditional methods of simply painting structures, contractors and homeowners prefer to add functionality and support to their building’s facade using various cladding materials, including ACM panels, wood sidings, longboard sidings, etc. For homeowners on their first renovation or new building project, choosing the most efficient cladding system from the array of materials and styles that the market offers can be a daunting statement. If the project requires modernity and flexibility of exterior cladding, it will be challenging to choose between wood, vinyl, ceramics, and aluminum composite panels. The first thing that most people consider when selecting their exterior paneling system is the price. While building materials such as wood and brick tend to come in at about 3$-14$ per square foot, with high-end wood cladding, which is the most expensive system currently, ACM panels often cost anywhere around 15$-35$ per square foot. However, there are several reasons behind the relatively expensive cost of aluminum composite panels.

Advantages of ACM Panels that Make Them More Expensive Than Other Systems

Aluminum composite panels (ACM panels), also known as ACP materials, are created by bonding and securing two aluminum sheets to unique core material. These panels are designed and engineered to provide long-lasting durability for homeowners who want to invest their money in the new construction or renovation of buildings. Using ACM panels offers numerous benefits when used as a facility’s cladding material, making them relatively expensive than other cladding systems. These practical advantages are as followed:

ACM Panels Provide the Best Durability Among Cladding Systems

The production process of ACM panels for providing cladding systems is the key to their popularity. Two sheet metals adhere to a thermally resistant polyethylene core which often features thin characteristics. The resulting aluminum composite panels are lightweight, and molding or fabricating them into different demanding shapes and styles is relatively straightforward. These particular rain-screen systems consist of additional coating that enhances their waterproof property and protects them against dents due to high-impact weather conditions. Metal panel cladding products are all factory-tested for their ability to withstand various damaging external factors. All ACM panels that are adequately produced offer:

  • High wind loads resistance
  • Structural supports during precarious conditions
  • Presumption deflection
  • Air infiltration and leakage protection
  • fireproof characteristics (safety regulations require fire-resistant features for exterior cladding systems)
  • Moisture and humidity resistance (for buildings in locations with high humidity levels)

These characteristics of ACP materials make them unbreakable and impervious to tear or wear from the worst of weather conditions during the year.

The versatility of Aluminum Composite Panels

Other cladding materials such as wood, vinyl, and stone can provide unique visual aesthetics and appeal for architects. However, these cladding systems have a limited range of styles, making them challenging for creating a new and modern appearance for the building. For instance, the stone is often preferred for its rustic, rough appearance and cannot accept other paints or finishes, resulting in the color choice reduction for customers. Moreover, molding and fabricating stone and wood can be challenging due to the current designs featuring curves and modern looks.

In contrast with traditional materials, ACM panels are incredibly flexible and lightweight, making them the perfect materials for fabricating in different designs. Additionally, the light characteristic of ACP materials allows builders to install them more straightforwardly. Manufacturers can shape aluminum composite panels into circles and curves as well as more traditional rectangles or squares. Another essential factor making these cladding systems more versatile than other paneling materials is that choosing any color during the mixing and finishing stage is possible, allowing architects to select from any color under the sun to suit the aesthetic requirements for their customers.

ACM Panels Require Low Maintenance During Their Lifespan

Wood siding cladding systems that are entirely made from natural wood require regular maintenance. While the natural appearance is more appealing to some people, using non-composite cladding materials requires consistent painting, oiling, and finishing. Water infiltration and pests can easily cause several damages to these products, including splitting, erode, and cracks.

On the other hand, ACM panels don’t require regular maintenance, primarily when the building is located in temperate areas. Cleaning aluminum composite panels usually require a simple wash and buff for removing any visible stains. With the highly reflective nature of aluminum surfaces, ACP materials are incredibly resistant to tear and wear from UV rays existing in sunlight, allowing them to maintain their finish and appearance for even decades.

Rainscreen Construction Principle (Part III)

Rainscreen Construction Principle

Rainscreen construction principle has become an essential part of the buildings industry over the years. With the growth of technology and engineering, manufacturers managed to produce modern and efficient cladding materials such as ACM panels considered rainscreen systems for the building’s exterior. This principle’s primary purpose is to protect the facility’s structure from damaging elements such as wind loads and water infiltration.

In the first part, we provided the basics of the system, which every customer or specialist in the building industry must know. These practical systems are available in two types: Drained/Back-ventilated, which rely on the ventilation cavity, and pressure-equalized methods, which employ drainable compartmentalization for water penetration limitation. PERS method is functional during pressure disequilibrium and facilitates fast pressure equalization. It also minimizes and under certain weather conditions to eliminate water in the product’s cavity. However, you should read the second part of the article for more information about the pressure-equalized system in the rainscreen construction principle. Moreover, in this article, we will discuss mainly the D/BV and its functionality.

Drained/Back-Ventilated Rainscreen Construction Principle

Drain/Back-Ventilated rainscreen construction principle is a practical method of protecting the facility’s exterior, which is utilized in many cladding materials such as aluminum composite panels or ACM panels with various properties, advantages, and functionalities. This system employs a series of boards, sheet metals, or planks called claddings fixed to vertical support channels or rails. The supports are the outer exposed barriers or leaves.

Joints in the external claddings are open but have a unique design to obstruct water infiltration by wind force or kinetic energy. It is essential to note that engineers create these systems to minimize the infiltration, not eliminating it thoroughly. Water leakage occurred from variable air pressure due to the wind is inevitable. Thus, a considerable amount of water can infiltrate the outer leaf through its open joints. However, the system permits the water to run down the interior surface of the outer barrier with a particular control system by the ACM panels designs including vertical channels or rails combined with water head leaves in a horizontal jointing system which directs the liquid flow to the vertical components. Little wetting in the inner barrier surface can happen, which is acceptable and will cause no issues.

The series of vertical channels have a design to collect the infiltrating water and drain it through gravity action. Additionally, they cross-direct at penetrations to the lower level and external section of the outer barrier. The system penetration should have continuous flashing and detailing to collect and direct water to the external obstacles or redirect it into the vertical drainage channels.

The minimum allowable width of air space known as a cavity between the outer and inner barriers is essential to facilitate positive back-ventilation in the ACM panels. This can promote rapid evaporation of any rainwater deposited in the surfaces of the inner surface of the aluminum composite panels or any other rainscreens. However, cavity depth should be considered to be in addition to the center of cladding applied to the building’s facade not to restrict the ventilation flow.

The internal leaf is typically the structural building close wall. Thus it can accept various construction methods. However, the water-resistant insulation should be applied to the exterior side of the cladding material and is an optional term to the thermal design requirements. The use of insulation is to maximize useable building space and rule out condensation and cold bridging to the interior surface of the inner barrier. Since the Dried/Back-Ventilated rainscreen construction principle is not a pressure equalized system, the aluminum composite materials or aluminum sidings considered building claddings must have a precise design to withstand 100% of the wind load.

Difference Between the Two Types of Rainscreens

D/BV rainscreen construction principle and PERS are both designed to increase the efficiency of the building. However, like any other industrial system, they have their differences.

The most notable thing about drained and back-ventilated systems is that leakage for claddings is allowed, and there is no deliberate attempt to minimize the effects of wind loads. Instead, the cavity behind the cladding material is drained, and positive back-ventilation usage promotes the evaporation speed of any rainwater on the inner barrier.

On the other hand, the main point about the pressure-equalized rainscreen construction principle is that without relying on sealants or gaskets in the installation process, every effort is made to minimize or eliminate the leakage through the joints. However, there could be some minor leakage into the cavity, and a drainage mechanism is essential. Additionally, positive back ventilation is utilized to increase the evaporation rate of water which permeated through the inner barrier of the ACM panels.

How do you paint ACM panels?

Paint ACM Panels

ACM panels are modern and practical cladding materials currently used for various applications, including commercial and industrial building projects. Due to the wide range of ACM panels advantages, from extreme weather durability and minimum requirements for maintenance to aesthetics and modern appearance, architects and builders prefer to use them instead of traditional building cladding materials. However, for many reasons, which we will discuss in the next paragraph, one of the most critical questions for aluminum composite materials is how you should paint ACM panels.

Aluminum composite panels often offer a longtime service which can sometimes exceed 20 years if maintained properly. However, customers may encounter minor damage or peeled paints on the cladding material when buying a home with ACM material for its facade. The good news is that by utilizing proper painting supplies and particular substances, resurrecting these metal claddings will not be challenging, and such issues should no longer be a concern. Thus, it is more cost-effective to paint ACM panels rather than replacing them or reinstalling a new board. The paint finish recovering process is considerably straightforward, and most homeowners can take care of it without any need for professionals.

Equipment and Tools Needed to Paint ACM Panels

Some essential equipment and tools are needed to paint ACM panels with the best quality, resulting in more durable finishes and better aesthetics. These tools and equipment are including:

  • Primer with an Oil Substance: This is used for sealing any porous surfaces, and it will allow the paint for better coverage of ACM panels.
  • Acrylic Paint: For better paint bonding on the cladding material, it is practical to utilize exterior acrylic paint.
  • Brushes with Synthetic Fibers: When working with acrylic brushes, it is essential to use synthetic fiber brushes to paint ACM panels.
  • Lambswool Roller: For having a smoother paint finish and maximizing the surface area coverage, utilizing a lambswool roller can be helpful.
  • Simple Ladder: Use a ladder to reach and access the higher sections of the cladding material.
  • Plastic Bucket: The painter can hang the paint bucket from the ladder during the process, increasing the work speed.
  • Plastic Paint Trays: It is necessary to utilize plastic paint trays for lambswool rollers.
  • Drop Cloths: It is essential to keep the painting area clean with drop cloths during the job to avoid splattering the paint on the floor, which will be difficult to remove.

ACM Panels Painting Steps

There are a few yet essential steps to take when considering painting ACM panels without asking for help from experts. These painting steps are also practical for other cladding materials, including Aluminum sidings. Each phase has its particular role, and to paint ACM panels, the painter should follow them precisely.

Step One: Preparation for Painting ACM panels

Preparing aluminum composite panels for painting starts with scraping off paints that are already damaged or peeled with a scraping tool. Then the painter should remove any mildew with ten-part water to one part bleach combination. If the ACM panel is dingy, it is recommended to rent a power sander and sand down the cladding.

Step Two: Applying the First Coat of Primer to Paint ACM Panels

The second phase to paint ACM panels involves creating a first coat of primer when the weather is mild and dry for preventing different factors such as rain and debris from destroying the paint finish. Using a paint-roller will make the process easier, and it can apply the primer evenly while taking a few seconds per 0.09 meters. Additionally, it is essential to use the first coat in only one direction for maximizing the dry time.

Step Three: Adding a Second Layer of Primer

After applying the first coat of primer, the painter should add the second layer after the first layer is dried thoroughly. Generally, primer takes about four hours to dry. Thus, it is more efficient to start the process accordingly.

Step Four: Start Painting the Cladding Material

The most efficient way to paint ACM panels is to do the process from top to bottom by using long and even brush strokes. For better results, it is recommended to paint the aluminum composite panels in the same direction as installed, whether horizontal or vertical.

Step Five: Applying the Second Coat of Paint

After the fourth step, it is essential to wait about two hours to dry and then apply the second paint layer. This phase will help the painter correct any flaws that occurred during the cladding material painting. Buying an extra gallon of paint is practical for additional touchups.

Step Six: Inspect the ACM panels to Find Issues

Once applying both layers of paint is finished, the paint-finish must be left to dry for at least 3 hours. Then it is crucial to inspect the work for missing spots, drips or bumps. If there is a sign of the old ACM panel finish notable beneath the new finish, the painter should apply one more paint coat.

How to Clean Aluminum Siding

Clean Aluminum Siding

It is essential to Clean Aluminum siding to maintaining the beauty of a facility and make it look fabulous like its first day of construction. Aluminum Siding is one of the most popular choices for building facades across Canada and the world. The durability and versatility of this cladding system are some of the many reasons behind its popularity. Aluminum sidings can last long if cleaned and maintained correctly. However, many homeowners who choose this type of cladding material do not know how to clean aluminum siding. For getting the most out of this product, it is required to invest some money and time to keep it looking like it is straight out of the factory. There are various methods available to clean aluminum siding, and each one has its unique advantages and challenges. However, all systems follow one principle, which is introduced in this article.

Methods used for Cleaning Aluminum Siding

Before choosing the appropriate cleaning method for aluminum sidings, it is essential to learn about techniques used for the purpose. The followings are a few of the practical cleaning systems that can wash the building’s cladding material thoroughly.

Rinsing: Like running a dishwasher on the rinse cycle before using the standard process to have better results, it is necessary to deliver a quick rinse before performing the metal siding’s primary cleaning. The rinsing can be accomplished with a well-directed stream of water from any source of water, especially from a hose. It is crucial to direct the spray in a downward direction over the cladding material. Suppose the spraying is done in the upward drift. In that case, it will cause water penetration under the material by gaining entry in the drainage holes located under the lower section of the aluminum siding. This can also happen in the ACM panel cleaning process. Most of the grime and dirt will fall be cleaned with a simple rinse. However, it is recommended to work from top to bottom.

Hand Washing: The easiest DIY method to clean aluminum siding is hand washing. By using this technique, homeowners can remove any dirt remaining on the building’s cladding. Utilize a bucket of warm water with cleaning solutions along with a soft-bristled brush and start scrubbing any grime existing on the siding. It is essential to clean with the length of the siding product, starting at the top and proceeding downward. For preventing the surface from drying out, it is better to do the cleaning in few meters from top to bottom and then do the rinsing. Wash dirt and soap off using a hose, directing the stream in a descending trail. If there are still stains on the product’s surface, it is required to use the mildew or pressure washing method.

Mildew: If there are stains caused by mold, it is practical to use a solution of one part bleach and four-part water and then spray the mixture on the spots. The cleaning method for removing mildew will often be required in more humid areas. Scrubbing with just a simple soft brush and water with detergents will not obliterate the mold thoroughly.

Pressure Washing: For more persistent stains, using a pressure wash to clean aluminum siding will be necessary. These machines can be obtained or rented at affordable prices from home improvement centers. Utilize a pressure washer that accommodated the mixing of the water and the cleaner together. Never use potent pressure due to the potential damages it can cause to the cladding material. This technique will remove every dirt, and it requires top to bottom workflow.

Choosing a Cleaning Method

The essential step to clean aluminum siding or other cladding products including ACM panels is choosing the suitable method for the material. As told, various systems can be used to complete the cleaning process with the best results. There are primary tasks to do before starting the process, which is as followed:

  1. Check for Rotting or Loose Panels: It is essential to remove or replace siding panels or recyclable ACP materials that show signs of damages or rots. Always nail and fix considerably loose boards. Always avoid using the pressure washing method until the fixing and repairing are done completely. Pressure washing can increase the instability and push water through the aluminum siding and soak into the building’s structure. If the homeowner is not confident with the DIY repair process, it would be best to contact a trustable siding contractor.
  2. Check the Aluminum Siding for Mildew: The second thing to check is to look for green, grey, or black stains while examining any grooves and the bottom of the cladding when the owner decides to clean aluminum siding. This step is essential for the area of the building that does not get much sunlight. For destroying and cleaning mildew, using the most potent cleanser is required. Even pressure washing will not prevent decay from growing back quickly.
  3. Look for Chalking on the Siding with Paint Finish: The last step for choosing the best method to clean aluminum siding is to put work gloves on and rub gloved hands on the surface of the cladding material. Consider using the pressure washing technique if there are signs of chalking, dirt, or grime on the gloves.
