Reasonable installation steps of doors and windows not only have good functions, but also have high efficiency and stability at the same time. The installation procedure guide for weidun broken bridge aluminum doors and windows is as follows:
1. A gap of 15-20mm should be left in the window frame and wall.
2. Remove the window from the window frame. If the window is not covered by a protective film, use masking tape to protect the window frame.
3. Lift the window frame firmly and pad the wooden block under the window frame.
4. Measure the position of the window frame at this time.
5. Check whether the installation gap and the vertical position and diagonal of the window frame are correct.
6. Use cushion blocks to ensure proper installation position or use traditional methods.
7. Make holes in the window frame and wall, and then rotate the support into the holes to fix the window frame.
8. Install the window and adjust its position if necessary.
9. Remove dust between walls and window frames and use damp.
10. Prepare polyurethane foaming agent. (Fix the foaming agent on the glue gun, shake the material tank and adjust the glue gun).
11. Using water can improve the efficiency of foam and reduce the cost by up to 30%.
12. Fill the foam into the gap between the window frame and the wall. 70-90% of the gap depth is enough, with uniform sizing from bottom to top. When sizing, keep material tank straight down. If the sizing speed is too fast, the gas will be lost and the efficiency will be reduced by foaming agent.
13. After the foam is solidified, remove the wedge and pad and fill the gap with foaming agent.
14. It is recommended that after 24 hours, after the foaming agent is completely cured, remove the excess foam and apply the plaster outside the foam.
15 after using plaster and finishing work, remove the protective film from the window.
The above is the installation procedure of weidun broken bridge aluminum doors and windows. I hope I can help you.
