# 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.**
### Get in touch
## Where are composites used in windows and doors?
We offer a wider range of solutions for window and door applications:
- glass fibre door profiles
- glass fibre window profiles
- composite window sashes, frames, and mullions
- composite door frames
- composite door and sliding doors & sills
- composite door internal stiffener profiles
- threshold profiles
- external parts for wood windows

## 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
### High quality
Our 60 years of pultrusion and pull-winding expertise. Choose from a wide range of aesthetic treatments, patterns and colours

## 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. Check out our window & door guide and infographic and learn more about the great benefits of composites.
