How should the door and window seals be used? What should you pay attention to before installation?

Generally, when we use the window seal, there will be a case where the window is not tightly sealed, and it is easy to let dust enter. Then, the following is the knowledge of how to use the window seal of the door and window seal.

The function of the window seal is to prevent dust, water, sound, and seal. Seals and door and window seals on the market are generally formed by extrusion of PVC, modified PVC, EPDM, elastomer seals, silica gel, etc. to form a good waterproof, sealed and so on.

Avoid some dirty things and some sundries during installation. Do not pull the door and window seals too tightly during installation. Also use a sealant to fix it when the quick installation is successful. The glass installation is not centered, the gap between the glass and the window frame is uneven, the rubber sealing strip is not close to the glass and the window frame, and the installation is uneven. Knocking on the glass by hand, there is a loose sound. The reasons for this:

1. When installing the glass, the debris in the notch is not removed in time, so that the glass and the notch are not aligned.

2. The gap between the glass and the glass slot is uneven, the rubber strip is in poor contact with the glass and the glass groove, and the glass slot is protruded, and the sealing strip can be easily pulled off by hand.

3. The rubber strip is not broken at the corner, and it is not glued.

We should do this:

1. Before installing the glass, carefully remove the debris in the slot, such as mortar, brick scraps, wooden blocks, etc. When the glass is placed, it should be carefully centered to ensure uniform clearance on both sides, and fixed in time to prevent collision displacement and deviation. The center of the slot.

2. The rubber sealing strip can not be pulled too tightly, and the length of the blanking is 20-30mm longer than the assembly length. It should be set in place during installation, the surface is straight, and it is in close contact with the glass and glass slot, so that the surrounding force of the glass is evenly distributed. At the corner, the rubber strip should be beveled off and glued firmly at the break.

3. When sealing the glass with sealant, the glass should be squeezed with rubber strips or rubber blocks to leave a gap of glue injection. The depth of glue injection should be no less than 5mm. Before the glue is cured, the glass should be kept from vibration.

The key to the door and window is the sealing, and the sealing of the sealing strip plays a decisive role. The sealing material used in the market is generally modified by PVC. The key function in soft PVC is nothing more than the addition of plasticizer inside. With the rising price of various petrochemical products, the sealing strip The price of rubber products is also increasing.
