Detailed Product Description

The superior heat insulation bridge-cut-off aluminum-plastic composite profile uses aluminum alloy at the inside and outside surface, and innovative cavity heat insulation design at the center. Its heat insulation performance is obviously better than that of normal profiles. The heat conductivity of the window can reach 1.6W/m2_k, much higher than the

new national standard for the energy saving of doors and windows BNBM door & window varieties include inward window, outward window, side and up hung window, bottom hung window, slide window, special shaped window, side door, slide door, superior heat insulation bridge-cut-off aluminum plastic composite door and window, and aluminum alloy door and window.

BNBM heat insulation aluminum-plastic profile adopts triple hermetic structure to scientifically separate air and water cavities and realize constant pressure balance between air and water, obviously improving the air and water tightness of the door and window. This technology passed the science & technology achievement Certification by the Science & Technology Department of the Ministry of Construction on November 5, 2004
