FRP and polyurethane door and window systems are building envelope components designed for thermal insulation, corrosion resistance, and dimensional stability. They use pultruded composite profiles for frames and sashes, combined with glazing and hardware. These systems are used in industrial, commercial, and high‑humidity buildings.
What are Composite Door and Window Systems
Door and window systems made from FRP or polyurethane profiles combine low thermal conductivity with high strength. The frame profiles can be engineered to specific cross‑sections to meet structural and thermal requirements. Performance depends on profile design, glazing method, sealing system, and installation quality. These systems are often selected for corrosive or hygienic environments.
Typical Building Environments
Composite door and window systems are commonly used in chemical and pharmaceutical facilities, coastal buildings, cleanrooms, and high‑performance building envelopes.
Frequently Asked Questions
Do FRP window frames require painting?
FRP and polyurethane frames generally do not require painting for corrosion protection. However, sealants and gaskets may need inspection and replacement over time depending on exposure conditions.
Can these systems meet high wind load requirements?
Wind load capacity depends on the profile section properties, glazing support, and anchoring. Systems can be engineered for high wind zones, but each project requires structural verification against the specified loads and building code.
