We are a leading Chinese manufacturer and supplier of fiberglass window frames, offering premium FRP and GRP frames for commercial, industrial, and residential projects. Durable, lightweight, corrosion-resistant, and customizable for global B2B needs.
Product Overview — Pultruded fiberglass window system
The Fiberglass Window Frame delivers high strength, stable dimensions, and long life for commercial and industrial buildings. Built as a pultruded fiberglass window system, it resists corrosion, UV exposure, and temperature swings while keeping lines straight and tolerances tight. Procurement teams choose this frame to balance energy performance, durability, and total lifecycle value.
Use it for new build or retrofit where metal frames face corrosion or thermal bridging. Compared to aluminum, the Fiberglass Window Frame offers lower thermal conductivity and a closer coefficient of thermal expansion to glass, improving glazing seal reliability across seasons. It integrates cleanly with IGUs, hardware, and weather seals to create a complete, field-ready solution.
Key Advantages & Technical Features — FRP window frame profiles
- Structural integrity: Pultruded FRP window frame profiles offer high stiffness-to-weight and stable geometry for large spans.
- Energy efficiency: Thermally broken FRP frames reduce conductive heat loss; supports NFRC-rated fiberglass frame U-factor targets when used in a rated assembly.
- Corrosion & chemical resistance: GRP matrices withstand coastal, industrial, and high-humidity sites better than painted metals.
- Dimensional stability: Low CTE near glass helps maintain gasket compression and sightline accuracy.
- Acoustic comfort: With suitable glazing, typical Rw improvements support office, school, and healthcare specifications.
- Finish options: UV-stable gelcoat or architectural coatings; RAL/NCS color matching available.
- Fast installation: Precision-cut profiles, pre-machined hardware pockets, and tested corner joins reduce onsite time.
Specifications — GRP casement window frame
- Process: Pultruded fiberglass (FRP/GRP) with resin system optimized for UV and weathering.
- Profile wall thickness: 3.0–5.0 mm typical; custom on request.
- Thermal break: Integrated non-metallic barrier for reduced Ψ-value and improved condensation resistance.
- Glazing compatibility: Fiberglass glazing frame for double/triple glazing; common IGU thickness 24–44 mm.
- CTE: Approx. 6–10 × 10⁻⁶ /K (near glass; helps seal stability).
- Air / water / structural: Designed to meet project requirements referencing ASTM E283/E331/E330 or EN 12207/12208/12210 when assembled correctly.
- Hardware: Multi-point casement or tilt-turn sets; stainless or coated steel fasteners.
- Finish: UV-stable gelcoat or fluoropolymer paint; matte or satin sheen.
- Tolerances: Typical cutting tolerance ±0.5 mm; straightness ≤1 mm/m.
- Environmental: Low-VOC finishing; materials available to support RoHS/REACH compliance statements.
Applications & Industry Use Cases
Choose the Fiberglass Window Frame for coastal buildings, chemical plants, food processing, labs, data centers, transport hubs, schools, and healthcare. GRP casement window frame configurations suit ventilated spaces requiring robust hinges and seals. Pultruded fiberglass window system profiles also serve modular construction and prefabricated façades where repeatable accuracy matters.
