3 broken bridge aluminum doors and windows when designing and measuring, the size is always one to two centimeters smaller than the reserved window opening. This is to prevent the broken bridge aluminum doors and windows made in advance in the factory from being installed due to the size standard. Isn't it strange? The size is standard but cannot be installed.
Because the doors and windows openings reserved in the building cannot be special standard geometric figures, there will always be size differences, and the doors and windows processed by factory machines are accurate to millimeters.

Then the broken bridge aluminum window made during installation will definitely have a gap with the hole. How is this gap filled?
1. First of all, our installer will use the prepared small wooden blocks to flatten the windows. And measure with horizontal ruler to ensure that the window is flat.
2. Then fill Styrofoam between the gap between the leveled window and the wall, so that the gap is fully filled by Styrofoam.
3. Finally, after Styrofoam is firm, cut the excess parts neatly with a knife. Then, the sealing operation of the gap is carried out by using silicone sealant to ensure the sealing effect and aesthetic effect.
To sum up, the gap between broken bridge aluminum doors and windows and the wall is sealed with Styrofoam and neutral silicone sealant.
