How to waterproof aluminum alloy doors and windows

         Now, when people buy door and window equipment, they begin to consider waterproof performance. There are many rainy seasons in the south, and door and window equipment should be waterproof so that customers can identify it. Today we will discuss how to waterproof aluminum doors and windows. Doors and windows are mainly mechanical parts, so if they are not handled properly, leakage can easily occur in actual projects. The main reason is that the design of the profile drainage system is insufficient and the installation and construction are not in place. When rainwater passes through the profile holes through the gap between the sealant and the glass, it cannot be drained in time, causing water accumulation. If the time is too long, rainwater will penetrate into the wall through the assembly gaps of the profile and damage the interior decoration. Therefore, when designing thermal fault bridge aluminum doors and windows, a drainage system must be designed to avoid the possibility of water accumulation and leakage.

       In the design of aluminum alloy doors and windows, using the principle of isostatic pressing is an effective method to improve the watertightness of doors and windows. Aluminum door and window waterproof strips, EPDM rubber waterproof strips between the glass and chassis, support heavy rain along the outer wall of the profile. A small amount of rainwater enters the profile cavity under the glass through the gap, and the drainage outlet of the cavity outside the profile is opened. A small amount of rainwater is discharged into the water container of the window frame along the designed drainage path. At the same time, the detailed design of the dripping eaves is mainly to prevent the surface tension of water flowing into the cavity along the contour wall.

          The overlap between the window sill and the window sash is unsealed, the seam is open to the outside atmosphere, and the internal and external pressure balance of the stagnant drain pipe is balanced, so rainwater is discharged along the drain pipe to the top of the aluminum exterior window by its own gravity, I can move it. Install sprinkler panels and drainage units in the lower part. Small gaps cannot be sealed with sealant to cause leakage, so aluminum doors and windows should minimize exposed seams. If the seam is inevitably exposed due to structural reasons, the profile will form a 90-degree angle on the two contact surfaces at the seam to facilitate injection sealing.
