Product Overview

This GFRPU casement window is engineered for high-performance energy efficiency, durability, and corrosion resistance. It features steel-free, pultruded fiberglass-reinforced polyurethane (FRPU) profiles that provide exceptional thermal insulation without metal bridging. The outward-opening design, hinged on the side, maximizes ventilation and natural airflow, making it an ideal choice for both residential and commercial projects.

Key Features & Benefits

• Steel-Free FRPU Profiles: Eliminates thermal bridging, ensuring zero heat loss through the frame. The pultrusion process delivers uniform strength and dimensional stability.
• Outward Opening Design: Side-hinged casement opens outward, providing large ventilation space and easy access for cleaning from inside.
• High Air & Water Tightness: Multi-point lock hardware and EPDM seals combine to create a robust barrier against drafts, rain, and noise, meeting strict building envelope standards.
• Zero Thermal Bridge: The polyurethane core and fiberglass reinforcement offer ultra-low thermal conductivity (λ ~0.28 W/m·K), significantly reducing energy costs in heating and cooling seasons.
• Superior Corrosion Resistance: Salt-spray tested and resistant to chemical corrosion, UV aging, and moisture – perfect for coastal environments, chemical plants, and passive houses.
• Customizable Options: Available in a wide range of sizes, surface colors (including wood grain finishes), and glass configurations (insulated, Low-E, laminated tempered) to suit architectural requirements.

Target Applications

This GFRPU casement window is specifically designed for high-demand projects where energy efficiency, longevity, and low maintenance are critical. It is particularly well-suited for:

• Villas and luxury homes seeking superior thermal comfort and stylish aesthetics.
• Passive houses and net-zero energy buildings requiring airtight, thermally broken envelope solutions.
• Coastal construction where salt-laden air accelerates corrosion of metal frames.
• Chemical plants and industrial facilities where resistance to aggressive environments is essential.
• Commercial projects such as hotels, homestays, and office buildings aiming for green certification (e.g., LEED, BREEAM).
