Windows with GRPU brand

About GRPU™

Control of heat loss and heat gain through windows and doors is critical inany building. Together with Bayer MaterialScience China, Top Composite Technology developed a kind of polyurethane composite window profile.

According to thermal efficiency of the new profiles, polyurethane composite windows are more energy-efficient than most of thermal-break aluminum windows, with high resistance to wind load.

Polyurethane composite can also be used to manufacture large thermal breaks of insulation aluminum windows, named Super thermal break.

GRPU™ Window & Door System is composed of all these windows and doors with the polyurethane composite technology.

Jiangsu Top Composite Technology Co., Ltd. will be converted into a subsidiary company of Zhejiang DeYiLong Technology Co., Ltd. in 2018.
