Of course, aluminum alloy doors and windows are mainly designed by using the pressure balance principle. Therefore, aluminum alloy doors and windows have a very ideal waterproof function. It has a structural drainage system. The sliding design is inclined and stepped, and a drainage outlet is set, so the drainage is smooth and the water tightness is good.
Before purchasing, we should choose the use of the product. For example, the standards of waterproof and airtight for bathroom doors and windows and indoor doors and windows are different. Consumers must choose to buy aluminum alloy doors and windows products according to their needs. Pay attention to the processing technology of aluminum alloy doors and windows to see if there are any obvious welding errors and gaps in the products. You can also take a proper look at the section diagram of door and window products to see if its sealing level is not suitable.
During the construction, we must choose good sealing materials, carefully block all the joints between door and window products and walls, and clean up the dirt before silicone injection. And aluminum alloy doors and windows minimize exposed stitching.
The window frame is not sealed with the lap part of Casement, and the seam is open to the outside atmosphere to keep the internal and external pressure balance of the drainage hole with poor water accumulation, so as to ensure that rainwater can be discharged outdoors along the drainage hole under its own gravity. Doors and windows are also important components of architectural modeling, so their shape, size, proportion, arrangement, color and modeling have a great influence on the overall modeling of buildings.
How to do waterproof maintenance for aluminum alloy doors and windows?
First: since the general aluminum alloy 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 about 300mm from the window side. Before making waterproof coating, use the ash to be coated) and apply lead water and oil after cleaning.
Third: waterproof agent concrete should be added around the window to seal it. Please note that waterproof agent should be added, because when ordinary concrete is solidified, the concrete loses water due to water reaction, and the inside is hole-shaped, water will seep from the hole to the room, while adding waterproof agent of concrete is dense inside and will not seep water. Aluminum alloy doors and windows determine various performance requirements of doors and windows according to the use parts of doors and windows. For example, Windows and standard doors require certain requirements for heat insulation, sound insulation, watertightness and air tightness. Finally, users choose the appropriate color of the door and window frame according to their own preferences and the matching with other decorative parts.
Fourth: the handover position between the window frame and other materials should be disposable silverware set.
Fifth: add a water covering plate to the top of all open windows to prevent rainwater from flowing into the room from the seam upward from the opening.
Sixth: glass material and aluminum alloy frame material should be filled with sealant, do not use rubber strip.
Seventh: it is better to design a boss at the bottom of the window. The surface of the boss is located behind the glass surface, so that the water collected from all sides will not flow into 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 condensate diversion hole should be designed at a quarter of the glass material at the bottom of the window.
Tenth: pay attention to the second, third and fourth on both sides of the window. And the construction should be strictly done around the interface processing, according to the actual engineering experience, pay attention to the above ten points, the door window should not leak.
The following are several reasons for leakage of aluminum alloy doors and windows:
The design of aluminium windows is not thoughtful about leakage, the waterproof and sealing layer is not enough, and even some aluminium windows products do not design special drainage channels, which leads to the embarrassing situation that rain must leak. In addition, it is also a case of water leakage that cracks occur when the sealing rubber is aged and hardened.
Due to the lack of expertise in measurement and installation, there is a certain gap between aluminum alloy doors and windows and wall space, and even insufficient attention is paid to the joint point between aluminium windows and wall, and the length and width of materials are not uniform, it is also one of the reasons for leakage that the filling materials are not filled according to the manufacturer's requirements, the doors and windows are out of shape after installation, and the connecting rods of special corner doors and windows are not strictly sealed.
