Doors and windows are customized products, because the wall can not be a little error, this will make the measurement of doors and windows slightly smaller than the window hole, a certain size of doors and windows can better make doors and windows installed, and ensure the level of doors and windows, in the installation of aluminum alloy doors and windows, there will be gaps with the wall. What should we do with the gap between the windows and the walls?
The aluminum alloy doors and windows were filled with polyurethane foam glue and sealed with silicone. This method is more appropriate. It solves the problem of crack. However, the surface of silicone can not be painted on the surface. If the collocation of walls and doors and windows and sealants is not good, it will affect the overall appearance. Therefore, we should pay attention to color matching when using silicone glue. Generally, the white aluminum alloy doors and windows should be used in white aluminum alloy doors and windows, and the champagne and other colors of aluminum alloy doors and windows will be collocated with black silicone rubber. This ensures the overall aesthetic effect of the aluminum alloy doors and windows.
