What should I pay attention to when installing broken aluminum doors and windows?
1, the most basic principle is horizontal and vertical, which is not negotiable. Some workers like to measure with a plumb hammer. If the verticality measured by plumb hammer is purely accurate, it will be a little more accurate, but the difference is not big. Many workers are used to leveling with water, which is convenient and quick. So we don't have to care too much. Of course, if we meet someone who is willing to help you measure a little with a plumb, then we should be thankful.
2. After the window of broken bridge aluminum is positioned, it is necessary to nail expansion screws on the window frame. The installation standard of expansion screws is 50 cm per nail. In particular, at least two screws should be installed to fix the two sides.
3. Pay attention to the periphery of the window frame when installing, and keep a gap of 1~2 cm from the wall. This gap is used to hold styrofoam. If the gap is too small, styrofoam cannot enter, which is likely to cause the risk of water leakage. And styrofoam must be played very tightly and densely, and styrofoam should be perforated inside and outside. Good styrofoam should be white and very hard after solidification. The poor quality styrofoam is yellow in color, and some have a pungent smell. Life is too short. With the increase of time, poor quality styrofoam will gradually age and lose its waterproof and caulking functions.
Remember to clean the window frame before installing the glass. If the workers don't help clean, we'll clean ourselves. In fact, to put it bluntly, after the window is installed, the dust inside is absolutely invisible, and sealant will be applied behind it. It doesn't matter if you can't see me, but it makes people feel more at ease.
