The doors and windows are made of multi-cavity thermal insulation profiles, and the integrated bending EPDM foam isobaric rubber strip is used to close tightly; the patented sound insulation rubber strip has good air-tightness and water-tightness. The window sash adopts the hollow glass structure, so that the window truly shows the characteristics of sound insulation, heat insulation and heat preservation, saving a lot of heating and cooling costs.

The product adopts a patented floor drain drainage system, with smooth drainage and good water tightness.

At the same time, the straight material of the aluminum alloy door and window frame of the broken bridge adopts a hollow design, which has strong resistance to wind pressure and deformation, and has a good anti-vibration effect.    

The broken bridge aluminum profile can realize the three-layer sealing structure of doors and windows, reasonably separate the water vapor cavity, successfully achieve equal pressure balance of gas and water, significantly improve the water tightness and air tightness of doors and windows, and achieve the effect of clean and bright windows.
