I believe that friends who are not deep in the door and window mute industry will also understand. The door and window sealing strip should be sealed, and it has the function of mute. However, what I did not expect is that the silence effect cannot be achieved after installing the door and window sealing strips. The following editor recommends an ultra-quiet sealing strip for you-I-ECO silent sealing strip. It contains special sound-absorbing cotton, which can effectively absorb the noise of the movable window part leaking into the room, and has more sound insulation performance than ordinary sealing strips, which can improve the sound insulation performance of doors and windows by 35%. The new door and window sealing strip is durable, non-shrinking, invariant, and has strong elasticity. It can still maintain the original shape after many years, ensuring the sealing performance of the product, and the service life can reach 20 years.
