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.
Warm-edge spacer system maximizes energy efficiency and improves seal performance of insulated glass units
The pros and cons of uPVC Profile directly affect everyone's engineering benefits. During welding, the weld fillet may be cracked due to improper welding process. The processing technology, especially the two processes of cutting and welding, must be strictly controlled to improve the strength of th
