PU Composite Energy-saving window and door system
G-Ren Tech launched an epochmaking high-perfomance energy-efficient window and door material - PU fiberglass composite material, extending the application of new materials widely use the field of aerospace to the window and door system, and leading a innovation in a new generation of door and window materials.
G-Ren Tech, launching the epoch-making high-performance energy-saving door and window material -- fiberglass reinforced polyurethane profile. Apply the composite material that is widely used in the aerospace and auto industry to the civil door and window system.
G-Ren independently researches and develops the injection box, mold, and a series of design and production processes for PU composite complicated section pultrusion. At present, G-Ren's PU pultrusion process can achieve long-term stable production with a pass rate of more than 95%.
The GR85 series energy-efficient door and window system was certified by the German PHI (Passive House Institute) which meets the PHI certification standards for cold and cool areas while reaching the PHA grade.
