Many customers always feel that there are problems such as a little crooked or gaps after the doors and windows are installed. So why do these problems arise? After all, every door and window manufacturer is professional, so there shouldn't be such problems?
I have encountered some owners complaining before, why are there cracks in the doors and windows? Why can't it be perfectly fitted? What we explained to the owner is that because the walls are not standard, there will be room when measuring the doors and windows to ensure that the doors and windows can be installed smoothly. At the same time, it is also beneficial to leave some gaps in the doors and windows.
1. Leaving gaps in the installation of doors and windows can ensure that the level of doors and windows is accurate. Many building walls are so standard, and there are errors in the level. The difference between building walls with large errors will be 4-5 cm. When measuring doors and windows, they are all in accordance with Doors and windows are measured at a relatively low point, so it is normal for doors and windows to have seams. Some owners worry about air leakage and lack of heat preservation. Don’t worry about this. Door and window manufacturers will apply foam and waterproof glue to the gaps in the walls.
2. Leaving gaps in the installation of doors and windows can ensure the effective filling of styrofoam and waterproof glue. Styrofoam also has waterproof, heat preservation, and sealing effects. A good seal is terrible, and it will cause air and water leakage. Therefore, after the doors and windows are installed, the windows and walls must be sealed and insulated with foam glue and waterproof glue. Certain standards, we cannot require standard door and window products with a non-standard wall, so it is normal for doors and windows to have seams, but there must be no gaps after the doors and windows are installed.
