Aluminum alloy doors and windows frame installation, the box and the wall must be left between the joints? If the window frame on the mouth size is too small, direct contact with the wall, you can? Question added: is now in the installation of doors and windows, the box has been safe , Not hit the bubble. I would like to ask is not a small hole, no way to play bubble agent, which can also be through acceptance? Or must be demolished to re-hole, leaving a certain gap to play bubble? (Oh, I was a student in the internship, some uncertain is not through the acceptance.) If the wall and the box is not flexible connection, then what may lead to the consequences? More
This problem can be small or small. In principle, is to leave the gap, if the level of vertical diagonal no problem, then the door and window frame contact with the wall to play a little bit of blowing agent on the line, the contract is relatively small, do not worry too much.
Did you mean that you first grind the wall? If it is according to national standards: between the box and the wall must stay 5 mm seam. But the national standard is the minimum standard, Party is the highest standard. Treatment is a total of 6 mm on both sides of the seam, marked with styrofoam can be.
Direct contact with the wall, according to reason that is not standardized, but the problem is not a long time easy to deformation only thermal expansion and contraction of the truth should know Oh if there is no way to Minato
