Of course, the following points should be paid attention to when selecting doors and windows:
First: the wall thickness of the profile should not be less than 1.5mm, and the heat insulation strip in the middle should be PA66 nylon instead of pvc, because the thermal expansion coefficient of PVC is too different from that of aluminum, and separation will occur after a long time, the width of the heat insulation strip should not be less than 2cm, and the heat insulation effect cannot be achieved without heat. The profile should have a drainage system,
Second: The glass should be energy-saving glass,
Third: hardware must be brand,
Fourth: The installation must be standardized. Otherwise, no matter how good the window is, the effect will be poor. Stare at the installation and construction personnel, fill the foaming agent and seal the sealant tightly.
