Waterproof treatment is not a small problem. If waterproof is not done well, not only the air tightness and thermal insulation effect of the room are not good, but also the phenomenon of water leakage is relatively easy to occur in rainy days. So during the construction process,
aluminum alloy doors and windows should strictly handle the interface around, especially corner pointing. The specific practice is as follows:
First, since the general aluminum doors and windows are recessed, the window top must drip olecranon to prevent the capillary action of rain.
Second, around the aluminum alloy doors and windows should be coated with waterproof coating (asphalt) about 300mm from the window side, and the dust at the position should be cleaned and painted with lead water and oil before making waterproof coating.
Third, waterproof agent concrete should be added to seal the doors and windows. Pay attention to adding waterproof agent! Avoid water loss of concrete due to water reaction during solidification, and the inside is pore-like, and water seeps from the hole to the room.
Fourth, the handover position between the window frame and other materials should be disposable silverware set.
Fifth, the top of all open windows should be added with water covering board to prevent rainwater from flowing into the room from the gap upward from the opening.
Sixth, glass and aluminum alloy frame materials should be filled with sealant, do not use rubber strips.
Seventh, it is better to design a boss at the bottom of the window. The surface of the boss is located behind glass surface to prevent the water collected from all around from flowing to the room along the window sill.
Eighth, the sill plate at the bottom of the window and the glue-line of the window should be designed outward rather than upward, and the sill plate must also be designed with an outward slope.
Ninth, if it is a single glass, the bottom of the window should be designed in a quarter of the glass condensate diversion hole.
10. Pay attention to the second, third and fourth on both sides of the window.
Summary: As for the treatment methods of aluminum alloy doors and windows in the above ten points, I believe everyone has a certain understanding of the waterproof maintenance of aluminum alloy doors and windows. When there is water leakage at home, there is no need to be nervous. As long as you follow the steps, the installation is handled according to the steps in this article, and the problem will be solved soon ~
