Composites for window & door applications

Glass fibre window and door profiles

If you are currently using aluminum window profiles or PVC window profiles, take a minute to consider composites. Composite window profiles can be a great alternative to replace your slim aluminum windows.

Whatever idea you're thinking about, Exel Composites can help your window and door project take shape. Whether it's about improving energy efficiency, incorporating stronger, higher, narrower frames or maximising aesthetic qualities, our experts can help you realise your vision.

Our products deliver better thermal stability than aluminium and PVC, lower maintenance costs than aluminium and wood and higher stiffness than any of the traditional alternatives.

Whether you're working on a residential, commercial, or industrial design, our UK-based plant is ready to engineer, manufacture and deliver the high-quality composite solutions for your needs. We help you take advantage of the material characteristics available with fiberglass, carbon fiber, or a mix of both and use our expertise in pull-winding and pultrusion continuous manufacturing technologies to deliver consistent quality at the volumes needed.

So tell us your idea and together we'll make it a reality.

Benefits of composites

Stable & insulating

Natural insulator with high conductivity. Low thermal elongation. No brittleness at low temperatures. Fire resistant.

High strength & stiffness

High tensile strength supports larger frames. Create narrower frames and sills. Withstands high wind loads

Long life, low maintenance

No rotting or rusting. Moisture-resistant. Withstands years of UV exposure

Learn about composite door and window profiles

Already using other materials like aluminium or PVC? Composites can be a stronger and more thermally efficient alternative. Many of our customers who use aluminium or PVC window and door profiles have very easily integrated fibreglass and even carbon fibre frames into their processes.
