The glass installation is not centered, and the gap between the glass and the window frame is uneven,Building door and window sealing stripNot close to the glass and window frame, the installation is uneven. Hands on the glass, there is a loose sound.

Building door and window sealing stripThe manufacturer understands that the reasons for this situation are as follows:

1. When installing the glass, the debris in the notch was not removed in time, resulting in misalignment of the glass and the notch.

2. The gap between the glass and the glass notch is uneven, and the rubber strip has poor contact with the glass and the glass groove, protruding from the glass notch, and the sealing strip can be easily pulled off by hand.

3. The rubber strips at the corners are not disconnected and bonded.

The corrective action is:

1. Before installing the glass, the debris in the notch should be carefully removed, such as mortar, brick chips, wood blocks, etc. When placing the glass, the glass should be carefully aligned to ensure that the gap on both sides is uniform, and fixed in time to prevent collision and displacement and deviation from the center of the notch.

2.Building door and window sealing stripCan not be pulled too tight, the blanking length is longer than the assembly length2O-30mm. The installation should be embedded in place, the surface is flat, and the glass and glass notch are in close contact, so that the force around the glass is uniform. At the corner, the adhesive strip should be cut on an inclined plane and the broken part should be glued firmly.

3. When caulking and fixing the glass with sealant, squeeze the glass with rubber strips or rubber blocks to leave a gap for glue injection. The depth of glue injection should not be less than 5mm, and the glass should be kept without vibration before the glue is cured.
