Pultruded FRP and polyurethane frame profiles are composite lineals with constant cross-sections used in compatible door and window framing and fenestration systems. FRP profiles are produced by pultrusion, while polyurethane profiles can serve as thermal-break components where the framing design requires them.
Product Family Overview
Composite frame profiles include pultruded FRP frame profiles and polyurethane profiles for door, window, and related fenestration assemblies. Pultruded FRP profiles are produced as continuous lineal sections with constant cross-sections and can be supplied for applications requiring integration with glazing, weatherstripping, and hardware. FRP profiles can be considered where thermal and environmental performance are relevant selection factors, while polyurethane profiles can serve as thermal-break elements in compatible framing systems.
Selection Considerations
- Thermal transmittance – an important consideration when evaluating the thermal performance of a frame assembly.
- Structural span – influences the required profile depth, section geometry, and reinforcement.
- Profile fit – the profile section should be compatible with glazing, weatherstripping, hardware, and connection details.
- Dimensional stability – relevant to maintaining the required fit and geometry over the intended service conditions.
Frequently Asked Questions
Can FRP profiles be machined?
Pultruded FRP profiles can be cut and machined with suitable carbide-tipped tools. After cutting or drilling, exposed fibers should be properly re-sealed with a compatible resin or coating system where required by the application and installation practice.
What is the thermal conductivity of FRP profiles?
Thermal conductivity varies with the resin system, fiber content, and profile construction. FRP is generally less thermally conductive than aluminum, but the applicable value should be confirmed from technical data for the specific profile section and configuration.
