In order to install the window tightly and avoid air leakage and water seepage, the window sealing strip is usually installed, which can be dustproof, waterproof, soundproof and sealed, and has good performance assistance for both hollow glass and tempered glass. However, many people are not very understanding of it, especially in the installation of this piece, the following is to introduce the window sealing strip installation method and precautions.
Brief Introduction of Window Sealing Strip
Door and window sealing strip is mainly used in plastic steel doors and windows, aluminum alloy doors and windows, wood doors and windows and other architectural decorative doors and windows. The plastic steel door and window sealing strips on the market are generally extruded from PVC, modified PVC, EPDM, elastomer sealing strips (including TPV, TPE, TPR, SEBS), silica gel and other materials.
The window sealing strip can be divided into three categories according to the different uses of the door cover sealing strip, the wool strip and the glass sealing strip (rubber strip). The door cover sealing strip is mainly used for sealing between the door panel and the door frame, while the wool strip is mainly used for sealing between the door frame and the door leaf, and the glass sealing strip is mainly used for sealing between the glass and the door leaf and the frame.
Installation method of window sealing strip
1. Glass backing strip and sealing strip
(Window frame and window sash) After welding, the rubber strip shall be pushed into the profile notch with a special roller in the forward direction according to the correct surface, and the head of the rubber strip shall be pressed down into the profile notch at the same time.
Since the rubber strip is an elastomer, it may shrink back after rolling. The correct method is: when the rubber strip is installed at the interface at both ends, retract the two ends of the rubber strip a little to the middle, leaving a shrinkage allowance of 2-3cm, and then cut off the embedded notch.
2. Glass strip
Push the tip of the rubber strip into the profile groove manually according to the correct surface, and then press the outer surface of the rubber strip firmly to press the rubber strip into the gap between the glass and the profile. The rubber strips at both ends retract a little to the middle, leaving a length of 1-2cm, then cut them off and press them into the notch.
Window sealing strip installation precautions
1. Before installing the glass, the sundries in the notch shall be carefully removed, such as mortar, brick chips, wood blocks, etc. The glass shall be carefully centered when placed to ensure uniform clearance on both sides, and shall be fixed in time to prevent collision and displacement and deviation from the center of the notch.
2. The rubber sealing strip can not be pulled too tight, the length of the material is 20-30mm longer than the length of the assembly. The installation should be embedded in place, the surface is straight, and the glass, glass notch close contact, so that the glass around the uniform force. The rubber strip at the corner shall be cut off at the inclined surface, and the rubber strip shall be injected and bonded firmly at the broken place.
3. When filling and fixing the glass with sealant, the glass should be squeezed with rubber strips or rubber blocks to leave a gap for glue injection. The depth of glue injection should not be less than 5mm. Before the glue is cured, the glass should be kept from vibration.
4. The installation site of the wool top is generally on the window (door) leaf, the four surroundings of the frame leaf or on the sealing bridge (wind block) to enhance the sealing between the frame and the leaf.
5. The size of the wool is an important factor that affects the performance of sliding doors and windows and water tightness, and it is also an important factor that affects the opening and closing force of doors and windows. The size of the wool top is too large or the bristles are too high, which not only makes the assembly difficult, but also increases the movement resistance of the doors and windows, especially the initial resistance when opening and the final seating resistance when closing.
6. specifications are too small, or vertical wool height is not enough, easy to fall out of the groove, so that the sealing performance of doors and windows greatly reduced. The wool top shall be siliconized. The qualified wool top shall have a straight surface, smooth bottom plate and vertical hairs, no bending, no pitting on the bottom plate, and conform to the requirement of 0.2mm.
