What are the elements of UPVC Profile doors and windows?

UPVC Profile doors and windows must be installed in compliance with specifications. It is difficult for consumers to have tools to check the quality of the windows. LUMEI Profile manufacturers tell you a few tips, which can be selected from the following factors:

1. The surface of the UPVC Profile window should be smooth and flat, without welding fracture, the sealing strip should be flat, without crimping, without grooving, and the rubber strip should be odorless.

2. The frame and fan of UPVC Profile window have steel lining. The glass is installed smoothly and firmly and does not directly touch the profile. If it is double-layer glass, there should be no dust and water vapor in the interlayer, and the switch components are tight and flexible.

3. UPVC Profile windows must be professionally processed in the factory workshop, not on-site production.

4. When the UPVC Profile window is closed, there is no gap between the sash and the frame. The four doors and windows are all connected together without screw connection. The sliding doors and windows should slide freely, the sound is soft, and there is no dust falling off.
