The performance of the sealing strip determines the sealing performance of doors and windows

The sound insulation and thermal insulation of ordinary wooden door seals are very important because they are connected to the outside and are the weak link in sound insulation. The sound insulation of a door mainly depends on the thickness of the door panel and the sealing degree between the window sash and the frame. When we live in high-rise buildings, we often find that the key to why electric heating and air conditioning do not work is the poor insulation effect of doors and windows. The reason for this situation is that the tightness of the doors and windows is too low. Hot or cold air can directly enter through the gaps, causing severe leakage of cold or hot air inside the room. Even with good equipment installed, it still cannot solve the root cause. Most of the energy still quietly slips away. Doors and windows with low sealing not only have poor energy efficiency and consumption reduction, but also have poor sound insulation effect. The sound insulation of holes and gaps is also related to the wavelength or frequency of the incident sound waves, because the higher the frequency, the shorter the wavelength. Therefore, even small gaps can be detrimental to sound insulation for high-frequency sounds.
In the process of making wooden doors, T-shaped grooves can be made on the door stopper, and with the matching sealing strip, the door has excellent door sealing and sound insulation function. At the same time, it also reduces the noise emitted by the door when it is closed, and enhances the insulation and structural stability of the door. The sealing strip of a wooden door is directly related to its density. The sealing strip is "hidden" at the contact area between the door frame and the door leaf. High quality sealing strips feel soft, elastic, and have a bright appearance. Legitimate wooden door enterprises will add silicone sealing strips, which have particularly superior physical properties.
Silicone rubber sealing strips are completely different from ordinary rubber strips. They have excellent resistance to compression deformation, so the sealing contact surface can be made larger, effectively blocking the noise leaking into the movable window part! Compared to ordinary rubber strips, this sealing strip has more sound insulation and thermal insulation functions. It is durable and has a service life that is synchronized with the service life of doors and windows, once and for all, without any worries. It will not harden even at minus 50 ℃, and can withstand high temperatures up to 200 ℃. It is made of the same material as the pressure cooker sealing ring used at home, and has strong elasticity without shrinkage or deformation!
