Pultruded FRP and polyurethane frame profiles are the structural lineals used to fabricate door and window frames. This page explains how to select the right profile for your fenestration system.
Product Family Overview
Frame profiles are manufactured by pultrusion, creating constant cross‑section lineals with high fiber alignment. They accept glazing, weatherstripping, and hardware. FRP profiles offer low thermal conductivity and good corrosion resistance. Polyurethane profiles provide a strong thermal break.
Selection Considerations
- Thermal transmittance – affects energy performance.
- Structural span – determines profile depth and reinforcement.
- Profile fit – must match glazing and hardware dimensions.
- Dimensional stability – important for long‑term performance.
Frequently Asked Questions
Can FRP profiles be machined?
Yes, pultruded FRP profiles can be cut and machined with carbide‑tipped tools. Cut edges should be sealed with a compatible resin to protect exposed fibers.
What is the thermal conductivity of FRP profiles?
Thermal conductivity varies with resin and fiber content, but FRP is much lower than aluminum. Specific values should be obtained from the manufacturer’s technical data for the exact profile section.
