Installation skills of EPDM sealing strip

2021-11-19


EPDM sealing strip is used to fill the gap after the installation of doors and windows. EPDM sealing strip can not only prolong the service life of doors and windows, but also facilitate people's life to a certain extent. However, many people do not know much about it, especially in terms of installation. Here to introduce about EPDM sealing strip installation skills, installation precautions.

1.Installation skills of EPDM sealing strip

1. Before installing the glass, carefully remove the sundries in the notch, such as mortar, brick chips, wood blocks, etc., and carefully align the glass when placing the glass to ensure that the gaps on both sides are even, and correctly fixed in time to prevent collision, displacement, and deviation.

2, EPDM sealing strip can not be pulled too tight, the length of the material is 20-30mm longer than the length of the assembly. When installing, the installation should be in place, 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 uniform. The rubber strip at the corner should be cut off at the bevel, and glue should be injected into the fracture to make it bond firmly.

3. When sealing the glass with EPDM sealing strip, squeeze the glass with rubber strip or rubber block, leaving a gap for glue. Glue depth should not be less than 5mm. Before the glue is cured, the glass should avoid vibration.

2.EPDM sealing strip installation precautions

1. Before installing the glass, carefully remove the sundries in the sink, such as mortar, bricks, wood blocks, etc., and carefully adjust the glass when placing the glass. Ensure that the gaps on both sides are uniform and fixed in time to prevent collision displacement and deviation from the center of the groove.

2. The EPDM sealing strip cannot be pulled too tightly, and the punching length is 20-30mm longer than the assembly length. The installation should be fixed, the surface should be straight, and close contact with the glass and the glass groove, so that the force around the glass is evenly distributed. At the corners, the rubber strip should be beveled and firmly glued at the break.

3. When sealing the glass with EPDM sealing strip, squeeze the glass with rubber strip or rubber block to leave an injection gap. The injection depth should not be less than 5mm. Before the glue is cured, keep the glass free of vibration.

4. The top mounting part is generally around the window (door) leaf, frame leaf or sealing bridge (windshield) to strengthen the seal between the frame and the leaf.

5. The top size is an important factor affecting the performance and water tightness of sliding doors and windows, and it is also an important factor affecting the opening and closing force of doors and windows. If the top size is too large or the vertical hair is too high, not only the EPDM sealing strip is difficult to install, but also the resistance of doors and windows will increase, especially the initial resistance and seat resistance when opening.

6. The size is too small, or the height of the standing roof is not enough, which is easy to leave grooves, which greatly reduces the sealing performance of doors and windows. The top is siliconized. EPDM sealing strip shall be flat, with smooth bottom and vertical, no bending, no pit at the bottom, and meet the requirement of 0.2mm.
