Waterproof treatment is not a small problem, if the waterproof is not done well, not only the air tightness of the room, thermal insulation effect is not good, but also prone to water leakage in rainy days. In the construction process, the aluminum alloy doors and windows should be strictly treated around the interface, especially the corner pointing. The specific operation is as follows:
First, as the general aluminum doors and windows are concave structure, the top of the window must be made dripping eagle mouth to prevent the capillary phenomenon of rain water.
Second, the aluminum alloy doors and windows should be coated with waterproof coating (asphalt) about 300 mm from the edge of the window. Before the waterproof coating is made, the dust on the position to be coated shall be swept and coated with lead water oil.
Third, windows and doors should be sealed with concrete with waterproof agent, and attention must be paid to adding waterproof agent! To avoid water loss of concrete due to water reaction during solidification, the internal is porous, and the water seeps from the hole to the room.
Fourth, window frame and other materials around the junction of waterproof sealant.
Fifthly, the top of all open windows should be added with a flashing board to prevent rainwater from flowing into the room from the opening upward.
Sixth, glass and aluminum alloy frame material to inject sealant, do not use adhesive tape.
Seventh, it is best to design a boss at the bottom of the window. The surface of the boss is located behind the glass surface, so as to prevent the water collected from all sides from flowing into the room along the windowsill.
Eighth, the joint between the sill and the window at the bottom of the window should be designed to face outward rather than upward, and the windowsill must also be designed with an outward facing 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 points on both sides of the window.
Summary: the above ten points about the treatment methods of aluminum alloy doors and windows, I believe you have 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 the installation is carried out step by step, the problem can be solved quickly~
