Doors and windows are usually fitted with seals, which can be dustproof, waterproof, and soundproof. However, many people are not familiar with it, especially in the installation of this aspect.
  
Door and window seals are mainly used in plastic steel doors and windows, aluminum doors and windows, wooden doors and windows, aluminum-clad doors and windows and other architectural decorative doors and windows. Market door and window seals generally by PVC, modified PVC, EPDM, elastomer seal (including TPV, TPE, TPR, SEBS), silicone and other materials extrusion formation. According to the use of different can be divided into door doors cover seals, tops, glass sealing strip (rubber) three major categories. The door/sleeve seals are mainly used for the sealing between doors and door frames, while the tops are mainly used for sealing between door frames and doors, and glass seals are mainly used for sealing between glass and doors and boxes.
  
Installation method of door and window sealing strip
  
   1. Glass mat and sealing strip
  
window frames, sash should be welded to the correct side of the rubber strip in accordance with the right direction with the special roller will be a little hard to push the rubber bar into the profile groove, while the rubber strip head downward pressure into the embedded profile groove. Because the rubber strip belongs to the elastomer, the roll pressure may result in retraction.
  
The correct method is: When the tape is installed to the two ends of the interface, the glue bar ends to the middle back to a point, and left 2-3 centimeters of contraction margin, and then cut the embedded groove inside the mouth.
  
   2. Glass Layering
  
The glue strip presses the correct surface to put the glue strip tip into the profile groove, and then press the exposed surface of the rubber strip to push the strip into the gap between the glass and the profile. The two ends of the rubber strip to the middle back a little, leaving 1-2 cm length after cutting, press into the slot.
  
   Precautions for installation of door and window seals
  
1, before the installation of glass to carefully remove the debris in the slot, such as mortar, brick, wood and so on, the glass should be carefully placed, to ensure that both sides of the gap evenly, and in a timely manner fixed, to prevent collision displacement, deviated from the Groove Center.
  
2, rubber sealing strip can not pull too tight, the length of the 20-30mm than the length of the assembly. Installation should be embedded in place, flat surface, and glass, glass groove close contact, soGlassThe surrounding force is even. The rubber strip at the corner should be inclined to disconnect and be securely bonded at the point of disconnection.
  
3, with sealing sealant fixed glass, should first use rubber or rubber blocks will be used to squeeze the glass, leaving the injection gap, plastic injection depth should not be less than 5mm, in the gel before curing, should keep the glass from vibration.
  
4, the top of the installation site is generally in the window (door) fan, box fan around or seal bridge (file wind block), enhance the seal between the box and the fan.
  
5. The top specification is an important factor affecting the push-pull doors and windows and the water tightness, and also affects the door and window switching force. Top specifications too large or too high, not only difficult to assemble, but also to increase the door and window movement resistance, especially when the initial resistance and closing when the final position resistance is greater.
  
6, the specification is too small, or the height of the vertical tops is not enough, easy to get out of the groove, so that the door and window sealing performance greatly reduced. Top need to undergo silica treatment, the quality of the top appearance of the surface is straight, the bottom plate and vertical hair smooth, no bending, no point on the floor, in line with the provisions of 0.2mm.
