Installation methods and precautions of common door and window sealing strips

doors and windows are usually installed with sealing strips, which can prevent dust, water and sound. However, many people don't know it very well, especially in the aspect of installation. Door and window sealing strips are mainly used for plastic steel doors and windows, aluminum alloy doors and windows, wooden doors and windows, aluminum coated plastic doors and windows and other architectural decorative doors and windows. The 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. According to different uses, it can be divided into three categories: door leaf, door pocket sealing strip, wool strip and glass sealing strip (rubber strip). Door leaf/sleeve sealing strip is mainly used for sealing between door panel and door frame, while wool strip is mainly used for sealing between door frame and door leaf, and glass sealing strip is mainly used for sealing between glass and door leaf and frame

installation method of door and window sealing strip

glass cushion strip and mouth stop adhesive strip: after welding the corners of window frames and sashes, push the adhesive strip into the profile notch with a little force with a special roller in the correct plane and direction, and press the head of the adhesive strip down into the embedded profile notch at the same time. As the rubber strip is an elastomer, it may shrink after rolling

the correct method is: when the adhesive strip is installed at the interface at both ends, retract both ends of the adhesive strip to the middle a little, leave a shrinkage allowance of CM, and then cut it and insert it into the notch

glass bead: manually thread the tip of the bead into the profile groove according to the correct side, and then press the exposed surface of the bead hard to press the bead into the gap between the glass and the profile. The rubber strips at both ends retract a little to the middle, leave a length of CM, cut it off, and press it into the notch

precautions for installation of door and window sealing strips

1 Before installing the glass, carefully remove the sundries in the notch, such as mortar, brick chips, wood blocks, etc. when placing the glass, carefully align it to ensure that the gap between both sides is uniform, and fix it in a timely manner to prevent collision and displacement, and deviate from the center of the notch

2. The rubber sealing strip cannot be pulled too tightly, and the blanking length is mm longer than the assembly length. When installing, it should be inlaid in place, with a flat surface and close contact with the glass and the glass notch, so that the stress around the glass is uniform. The rubber strip at the corner shall be cut off by an inclined plane, and the rubber shall be injected and bonded firmly at the cut-off point

3. When using sealant to fill the seam and fix the glass in recent years, the glass should be squeezed with rubber peak, time bar or rubber block first, leaving a glue injection gap. The glue injection depth should not be less than 5mm. Before the glue curing, the glass, such as binder, catalyst and internal release agent, should be kept from vibration

4. The installation position of the wool top is generally on the window (door) leaf, the perimeter of the frame leaf or the sealing bridge (wind block), so as to enhance the sealing between the frame and the leaf

5. The specification of wool top is an important factor affecting the performance of sliding doors and windows and watertightness, and it is also an important factor affecting the opening and closing force of doors and windows. If the top specification is too large or the vertical hair is too high, it will not only make assembly difficult, but also increase the resistance of door and window movement, especially the initial resistance when opening and the final resistance when closing

6. The specification is too small, or the height of the vertical top is not enough, which is easy to fall out of the groove, which greatly reduces the sealing performance of doors and windows. The wool top needs to be silicified, and the appearance of the qualified wool top is flat and straight. 1. Ball screw: the ball screw and trapezoidal screw are currently used in the electronic universal testing machine. The bottom plate and vertical hair are smooth, without bending, and there are no pits on the bottom plate, which meets the requirements of 0.2mm

the door and window sealing strip can not only prevent dust and water, but also play the role of sound insulation and sealing. The above is the introduction of the installation methods and precautions of door and window sealant strips. I hope it will be helpful to you
