Glass Fiber Reinforced Polyurethane (abbreviated as GRPU) is a high-performance composite material. It uses non-woven glass fiber yarn as the reinforcement material and polyurethane resin as the matrix resin, produced through injection impregnation pultrusion process. Due to its fiber reinforcement, it exhibits high compressive, tensile, and flexural strength. With increasing national requirements for building energy efficiency, this material has broken through into the energy-saving doors and windows field due to its unique advantages such as sound insulation, thermal insulation, fire resistance, aging resistance, low linear expansion coefficient, energy efficiency, and environmental friendliness.

In the application of doors and windows, polyurethane energy-saving sub-frames have significant advantages compared to broken bridge aluminum alloy and plastic steel. The doors and windows made from this material excel in thermal insulation, wind pressure resistance, air tightness, water tightness, sound insulation, fire resistance, corrosion resistance, and other performance aspects. Additionally, the surface of the profiles can undergo various coating treatments for rich visual effects.
