GR60 Low Power Consumption Fiberglass Reinforced Polyurethane (FRPU) Casement Window

Introduction：

The GR60 Low Power Consumption Fiberglass Reinforced Polyurethane (FRPU) Casement Window is a high-performance system for energy-conscious architecture. Its FRPU thermal break profile—80% fiberglass, 20% polyurethane—delivers 1442 MPa bending strength and thermal conductivity of just 0.114 W/(m².K), with only 17% of the carbon emissions of traditional aluminum systems. Multi-cavity profiles, triple EPDM sealing, and Roto hardware ensure excellent airtightness, water tightness, and sound insulation, while optional polyurethane foam filling boosts cold-climate performance. Ideal for luxury villas, boutique hotels, high-end apartments, and premium offices, its corrosion resistance, salt resistance, and 0-VOC formulation suit coastal and green-certified projects. Choose GR60—let every window make a statement of superior living.
