Aluminum Composite Material (ACM)

For a Fuss-Free Futuristic Look

Our Aluminum Composite Panels turn any building into the epitome of modern luxury. With a sleek design and a durable finish, ACM will neither fade nor fall out of fashion. One part armor, one part statement: your building wants to wear ACM for years to come.

What is ACM?

Aluminum Composite Material (ACM) is the cladding solution that continues to delight architects, assist contractors, and wow everyone who looks upon the exterior designs they create. ACM is a driving force in modern architectural design, and continues to provide the look and features that end users desire in a contemporary building’s exterior. Created and manufactured with facade in mind, Aluminum Composite Panels (ACP) are a synthesis of materials working together to meet the multitude of needs that cladding must solve. ACM obliges a multitude of design forms, is no bother to fabricate, and installs like it wants nothing else but to be on your building. When ACM clads your exterior, it will be the fancy of the block, and ready for whatever the future has to throw at it.

Wondering what ACM can do for your specific project?

ACM Layers

The best cladding solutions come from a synthesis of complementary materials. ACM is no exception. Here are the layers from which our ACP draws its strength:

Protective Film

This temporary layer protects ACM from scratches, blemishes, or any other damage that the shipping, fabrication, or installation process might incur. It is always a satisfying moment when installation is complete, as you watch the Protective Film be removed to reveal the beautiful design found beneath.


Polyvinylidene fluoride (PVDF) is the key to ACM’s resistance against elemental damage. Used as a state-of-the-art paint for our ACP, PVDF will shrug off any sort of weather, from sleet to acid rain, all while giving your building the gloss and color that its exterior deserves. The ACP we offer features three coats of PVDF; a primer, finish, and varnish that completes the look and secures the survivability of ACM cladding.

High Strength Aluminum Sheet

This is the layer that gives Aluminum Composite Material its name. If your building is going to battle, this is its armor. Aluminum is a dense metal, and stands strong against any physical damage a building might see in its lifespan. Its lustrous nature offers the polished and smooth look that is often attributed to buildings clad with ACP. Beyond the quality of this defining layer, aluminum is also an abundant resource, with a stable and reliable supply chain that contributes to the reputation ACM has for being logistically sound in any cladding project. Wiedehopf only offers the highest quality ACM, and the proof can be seen in this layer especially. Where some competitors skimp on this layer, our ACP features a .5mm High Strength Aluminum Sheet, which is suitable for a building’s exterior.

Non-Toxic Polyethylene or Fire-Resistant Core

The core, being the heart of an ACM panel, is the material that everything hinges on. The lightweight property of ACP is thanks to its core layer, which counteracts the density of the aluminum around it. Typically made of Polyethylene, the core layer is featherweight while being no pushover to high impact. We also offer a Fire-Resistant core, which maximizes safety and peace of mind. If you are cladding a building that exceeds four stories in Ontario, the Fire-Resistant core will be necessary to keep up to code, and will protect your building’s end users for years to come.

Chemosynthetic Oxidation Coating

Oxygen may be great for us, but it can wreak havoc on building materials–especially metal–over many years of steady exposure. This means rot, rust, and degeneration for many cladding solutions, but not ACM, thanks to this critical supporting layer. The ACP we offer has a coating designed to counter the impact of oxidation. While other layers protect against more apparent threats, this coating works behind the scenes to make sure that your building’s facade will not even know what rust is.

Anticorrosive Primer

Damage to a building’s facade can–God forbid–come from within sometimes. This is why the final layer found in the ACP we supply is coated in an anti-corrosive primer, which ties the entire material together with a layer that works alongside the Chemosynthetic Oxidation Coating to ward off rot and rust.

Commercial Property

For commercial properties, where contemporary design and ROI are critical to deciding the right cladding solution, ACM makes sense from many angles. ACP offers a professional and current look, that will not cost much time and money to maintain.

High Rise buildings

High Rise buildings are a beast to construct and maintain. ACM is the perfect cladding solution for its lightweight nature and its tested Fire-Resistance that will keep your building’s facade well up to code.

Residential property

Residential property is booming right now in Ontario. Homes that are clad with ACM project a luxury unlike anything else on the block. Tastes are evolving, and new homeowners everywhere seek designs that were only dreamed about prior. ACM offers a curb appeal that lasts! Its resistance to long-term damage is an asset to a home’s value on the market, and is one of the first things building inspectors will note when making appraisals.

Educational Buildings

Universities, and other education centers are often known for the future forward thinking that reflects in the buildings that make up their campuses. ACM is the cutting edge for cladding and facade design, and will make any structure into the Big Building on Campus. Sleek, contemporary, and long lasting, ACM’s look inspires students to think about the many possibilities that the future has to offer.

Healthcare Centers

When designing Healthcare Centers such as hospitals, clinics, and medical offices, you want a well maintained look that reflects the cleanliness of the building as a whole. A minimalist design, along with the labor saving environmental protection of ACM, can help any Healthcare Center achieve this goal.


More and more community centers, libraries and museums are turning to ACM for cladding. ACM design opportunities inspire creative and hopeful thinking about the future, and connote to visitors that the community around these buildings is on the cutting edge of growth.


As planes, trains, and automobiles continue to evolve, airports, subway stations, and parking structures also need to innovate. These stations are just as important as the vehicles they house, when it comes to the experience of commuters. ACM is a building material that looks just as novel as the latest mode of transport, and designs ranging from fun to elegant grant a holistic and welcoming commute.


There are many things that the industrial world has on its plate. With ACM cladding, labor-intensive façade maintenance does not have to be one of them. Manufacturing buildings, power plants, and research centers are well served by ACM and its long-lasting contemporary look.


From the Federal to the Municipal, newly constructed government buildings are adopting modern styles that invoke innovation and provide welcoming spaces to the community that they serve. ACM cladding is geared towards a finished façade that projects all this, through an aesthetic makeup that is future focused and widely appealing. ACM is reliable over years of wear, and has low maintenance needs, providing for a façade that instills stability without great future costs to taxpayers.

Extrusions and backplates come in a variety of forms, allowing for a precise frame that will hold ACM paneling and allow for a Rainscreen system. Extrusions are named for the way that they space out brackets from the base wall, affording space for an air cavity that will push rain and wind through and away from your building. All of the components that we pair with ACM during fabrication are extruded using 6063-T5 Aluminum, for the following benefits:

  1. The malleable qualities of aluminum make it perfect to extrude.
  2. Aluminum components are designed to simplify the process of cladding.
  3. For Rainscreen applications, the non-corrosive nature of aluminum makes it a perfect material to use.

Extrusions come before the panels, Installers fasten the vertical and horizontal end frames first, laying out the full perimeter in which the ACM paneling will be installed. The bottom of the building’s envelope is segmented with half back plates into which a reveal cap is locked. Then come vertical back plates, a long link for uninterrupted sections of the wall, and half link for around intricate areas such as windows and doors. More segmented back plates make up the horizontal brackets that will be fastened to the top and bottom of the ACM panels. These extrusions, by design, lift away from the base wall, so System Clips are added to bridge the gap to ensure structural integrity. With proper Extrusions in place, you can rest easy that ACM panels can be installed securely for a proper Rainscreen.

Fastening Systems

Extrusions are fastened to the base wall using screws that come in three different varieties, depending on whether the building’s envelope is composed of Wood, Concrete, or Metal. Each fastener type has a corrosion-resistant coating that protects against elemental damage that may incur over years of exposure.

Project Process

We will take ACM from sheet to panel, and get it on your building’s facade using a workflow we have developed over years within the cladding industry. Here are the steps we take in partnership with your ACM cladding project.


The infinite design possibilities of ACM can be overwhelming at first! Our designers know how to wrangle all of your ideas and wants into a design that you will take pleasure in for years to come. Before anything, we will provide you with a project estimation that includes the resources, costs, time, and square footage of ACM needed to carry out the cladding project you wish to accomplish. This estimation is sent to you through a quotation that informs you of all that will go into the project. Then, we bring the vision to life with detailed blueprints and 3D models, so that the look can be just right before it comes time to carve the design out of ACM sheets colored and textured to your specifications. Thanks to a detailed quote and an interactive design model, we limit any surprises that may arise during the full cladding process.


We keep a healthy stock of ACM at all times, in a variety of the most popular and versatile finishes. Even if you seek something niche in way of color or texture, we have strong partnerships with the most reputable manufacturers of ACM paneling, and can supply the material with expedient lead times and convenient shipping. We love ACM because of the abundance of its core materials in the market, so our partners and customers can enjoy a product that is readily available.


What a marble block was to Michelangelo, ACM sheets are to our CNC machine. This top-of-the-line manufacturing marvel cuts ACM with great speed, and without human error.
