7 major details that must be paid attention to when installing aluminum alloy doors and windows
Aluminum alloy doors and windows are loved by many owners and construction workers because of their stylish appearance and good physical properties. It can be said that aluminum alloy doors and windows play an extremely important role in modern home decoration. Although aluminum alloy doors and windows are popular among construction workers because of their simple construction process and low construction difficulty, there are many details that need to be dealt with in time to install aluminum alloy doors and windows well. So what are the things worth noting? Let's take a look at the 7 major details that must be paid attention to when installing aluminum alloy doors and windows.
1. Before installing aluminum alloy doors and windows, the shape, size and position accuracy of the door and window openings should be checked and verified. The supervisor and the construction party should check whether the number and position of the embedded concrete meet the design requirements; at the same time, for windows on higher floors, it should be checked whether the lightning protection belt is connected as required; for unqualified parts, the construction party should be urged to rectify.
2. After the aluminum alloy doors and windows are mounted on the wall, they must be adjusted and positioned with wooden wedges, and then fixed with nails. Note that it is forbidden to use iron nails and wooden wedges for fixing. The next step is caulking. Before caulking, the supervision unit (or construction unit) should make a record of the acceptance of hidden projects (water and electricity transformation and waterproofing projects, etc.), and check the verticality, horizontality, and diagonal angles of the doors and windows. After caulking, the wooden wedges should be removed in time to avoid being forgotten in the seams.
3. For doors and windows made of oxidized materials caulked with cement mortar, anti-corrosion and anti-rust treatment should be carried out before they are installed on the wall. Except for the window frames facing the outer wall, the other surfaces of the window frames are protected with adhesive tape or plastic tape. Special attention should be paid to the existence of adhesive tape or plastic tape on the window frames facing the wall, so as to avoid loose connection of the joints, resulting in poor waterproof performance, and thus water seepage and leakage in the gaps.
4. The waterproof glue between the aluminum alloy window frame and the wall must be applied after the wall is completely dry. At the same time, the base layer should be cleaned and de-graveled before applying the waterproof glue. If the wall is not completely dry and the dust is not cleaned, the water vapor released by the wall will make the sealing effect of the waterproof glue ineffective, and finally cause the entire window to leak and seep.
5. After the wet work of installing aluminum alloy doors and windows is completed, you can start installing glass and windows. Before that, you should remove the protective adhesive tape or plastic tape and the dirt on the window frame.
6. After the glass and sash of aluminum alloy doors and windows are installed, check whether the accessories are missing, whether the installation is firm, and whether the sash is flexible. The outward-opening casement window should be closed before acceptance to prevent the sash from being damaged by strong winds and rainstorms.
7. Before acceptance, the aluminum alloy doors and windows should be cleaned and self-checked. Cleaners that are corrosive to aluminum profiles, glass and hardware accessories should not be used; problems found in self-inspection should be dealt with in a timely manner and deficiencies should be repaired.
