Plastic steel windows must be professionally processed in the factory workshop, not on-site production.

When choosing plastic steel profiles, you must perform the correct operation according to the above instructions. Only in this way can its performance be fully displayed, thereby improving our work efficiency.

To solve the root cause of the rainwater leakage problem of plastic inner casement windows, we should start with the design of doors and windows, the most important of which is the design of water tightness and wind pressure resistance.

In the independent plastic cavity, a 1.5~3MM thick steel lining can be filled, and the thickness of the plastic steel and the profile series can be selected according to the local wind pressure value, the height of the building, the size of the opening, and the window type design to ensure Building requirements for doors and windows. Appropriate methods should also be adopted when packaging, so as to give full play to its ultra-high performance.

Water tightness is relatively good when uPVC casement window is closed, but the relative gaps between wall body and window frame, the frame fan overlap room, the gap between the glass and the seal, the inner and outer drain holes.
