1, before the installation of glass to carefully remove debris in the notch, such as mortar, brick chips, wood blocks, etc., glass should be carefully placed in the center, ensure that the gap on both sides is uniform, and timely more positive fixed, to prevent collision shift, deviation from the center of the notch.

2, the rubber sealing strip can not be pulled too tight, the cutting length is 2o-3OMM longer than the assembly length. The installation should be inlaid in place, the surface is straight, and the glass, glass notch close contact, so that the glass surrounding uniform force. The rubber strip should be beveled at the corner, and the rubber strip should be firmly glued at the disconnect point.

3. When sealing the glass with sealant, the rubber strip or rubber block should be used to squeeze the glass, leaving a gap for glue injection. The depth of glue injection should not be less than 5mm, and the glass should not be affected by vibration before glue curing.

4. The installation part of the wool is generally on the window (door) fan, around the frame fan or the sealing bridge (wind block), and the sealing between the frame and the fan is enhanced.

5, wool specification is an important factor affecting sliding doors and Windows and watertight performance, is also an important factor affecting doors and Windows switching force. Top specification is too large or erect wool is exexusive, not only assembling difficulty, and make door window mobile resistance increases, especially the initial resistance when opening and the final resistance when closing are in place larger.

6, the specification is too small, or the vertical top height is not enough, easy to come out of the slot, so that the sealing performance of doors and Windows greatly reduce the workbench picture. The top shall be treated by silicification, and the qualified top shall have straight surface, smooth base plate and vertical hairs, no bending, and no pitting on the base plate, which shall meet the requirements of 0.2mm.
