Building with composites

Have you thought about using composites?

Are you thinking about how you can get more out of your windows, doors, or other building applications? So have we. Composites, like fiberglass and carbon fiber, can be used in many different building applications. From fiberglass window profile frames to carbon fiber sunshade axes, the benefits composites provide not only help build more durable solutions, they also help lower lifetime operational costs though reduced maintenance. We work with a wide range of customers, from design engineers and fabricators to construction companies, to architects to OEMs to provide cost-effective composite solutions to many creative challenges

Common uses for composites

There are many areas where composites can be used in place of more traditional materials like aluminum, steel, wood, or PVC. Below are a few of the areas where our building composites are typically used.  


Window and door profiles

Composites like fiberglass provide many benefits in windows and doors. From helping improve energy efficiency to reducing manufacturing part count.

How to manage fire, smoke and toxicity requirements when specifying composites?

The mechanical properties of composites, such as weight, stiffness, and strength, are normally the deciding factor in the design process. However, in applications where there is a risk of encountering fire, smoke, and toxicity (FST) conditions, this becomes the primary consideration when specifying composite solutions.

To help companies operating in industries like transportation, building, construction, and infrastructure, navigate FST requirements, we have created an FST whitepaper to explain how fire considerations influence composite designs.

Exel Composites FST whitepaper

We use continuous manufacturing technology to provide consistent quality and high-volume output. These processes, called pultrusion and pull-winding, also allow for a wide range of fiber alignments and resin systems to better accommodate the many applications where composites are used. We can tailor the performance characteristics as well as surface qualities and aesthetics to meet a wide range of end-user needs. Our secondary processing options like drilling, cutting, sanding or grinding, as well as labeling and gluing add additional value and help simplify your supply chain.

Light weight

Lighter than aluminum and steel, you can save weight or move them around easier.

Strong and stiff

With strength that’s comparable or superior to steel and aluminum, composites consistently outperform plastics.


Our composites are delivered shape and specification ready.

Thermally efficient

Composites are excellent insulators and retain their shape in extremely hot or cold conditions.

Environmentally durable

Unaffected by salty or acidic conditions, our composites are corrosion and chemical-resistant.

Electromagnetic transparency

Fiberglass has lower signal attenuation helping to keep data connectivity where its needed.
