Glass and sealing strip installation skills

The key of doors and windows is sealing .and the sealing strip plays a pivotal role.In the door and window manufacturing process, the cost of the sealing strip accounts for a small proportion, but its role cannot be ignored. Today I share the installation tips of the glass and sealing strip.

The glass is not installed in the center, the gap between the glass and the window frame is uneven, and the rubber sealing strip is not close to the glass and the window frame, and the installation is uneven. Knock the glass with your hand, there is a loose sound. The reasons for this situation:

       1. The sundries in the notch are not removed in time when the glass is installed, so that the glass is not aligned with the notch.

       2. The gap between the glass and the glass notch is uneven, and the rubber strip is in 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 strip is not broken at the corners, and glue is not injected.

The corrective measures of the installation tips of the glass and sealing strip are:

1. Before installing the glass, carefully remove the sundries in the notch, such as mortar, brick chips, wood blocks, etc., carefully align the glass when placing it, ensure that the gap on both sides is uniform, and fix it in time to prevent collision, displacement, and deviation Center of notch.

2. The rubber sealing strip cannot be pulled too tightly, and the blanking length is 20-30mm longer than the assembly length. The mounting should be in place when installing, the surface should be straight, and it should be in close contact with the glass and the glass notch so that the force around the glass is even. At the corners, the rubber strips should be cut off at an inclined plane, and glue should be injected at the break to be firmly bonded.When sealing the glass with sealant, the glass should be squeezed with a rubber strip or block first to leave a gap for the glue. The depth of the glue should not be less than 5mm. Before the glue is cured, the glass should be kept from vibration.
