A brief analysis of the reasons for the leakage of the inward opening pvc window

1.Water tightness of uPVC Doors& Windows

The detection index of rainwater leakage performance of uPVC Doors& Windows is watertight, especially for high performance doors and windows it is one of the important reference indexes. In general, plastic doors&windows have better water-tightness than aluminum doors&windows under the same specifications. Flat- open windows are better than sliding windows. Water tightness is reflected in the waterproof and drainage aspects of doors and windows, that is, high performance doors and windows must have excellent prevention, not only on infiltrate rainwater but also should have good drainage capacity. Only these two are done, then it really achieved excellent water tightness.

2. Main leakage sites of plastic casement window

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. These are parts of rain leakage under wind pressure, pressure, etc.:

1) The rainwater passes through the gap between window frame and the wall body, the window frame and the splicing material.

2) Between the glass bead and the glass, under external pressure such as wind pressure may cause rain to infiltrate into the room.

3) There is water accumulation inside the frame room, and if the drainage system is unreasonable or the frame sash has a gap between the seals, which all cause the rainwater come into the room.

4) Leakage into the room through window hardware or a link to a processed hole (such as a screw connection).
