FRPU Windows
FRPU Windows Benifits
FRPU (Fiberglass Reinforced Polyurethane) window systems combine the flexibility and toughness of polyurethane resin with the high strength and dimensional stability of fiberglass, creating a next-generation material solution for energy-efficient buildings. Compared with traditional aluminum or plastic systems, FRPU profiles offer superior thermal insulation, corrosion resistance, lightweight strength, and long-term durability, making them ideal for modern residential, passive house, and commercial applications.

Window Type Advantages
Exceptional Thermal Insulation & Energy Efficiency
FRPU composite profiles feature naturally low thermal conductivity and multi-cavity structural design, significantly reducing heat transfer and improving overall building energy performance for passive house and low-energy projects.
Lightweight Strength with Long-Term Durability
Combining polyurethane flexibility with fiberglass reinforcement, FRPU systems deliver excellent impact resistance, dimensional stability, corrosion resistance, and fatigue resistance while remaining lightweight and structurally strong.
Sustainable Material for Modern Architecture
Manufactured through advanced pultrusion and winding technologies, FRPU profiles are environmentally friendly, highly durable, and suitable for premium residential and commercial window and door systems requiring modern aesthetics and long service life.
