The sealing strip contains special sound-absorbing cotton, which can effectively absorb the noise of the movable window part leaking into the room. It has more sound insulation performance than the ordinary sealing tape and can improve the sound insulation performance of doors and windows by 35%. Four-in-one wrap-type sealing strip, the sealing performance and resilience are more than 3 times that of EPDM strip, the air leakage is 1/3 of EPDM strip; the deformation pressure is also 1/3 of EPDM strip. At the same time, sound insulation, noise reduction, anti-haze, anti-ultraviolet rays, does not react with any paint, cleaning agent, green health is the guarantee of door and window insulation, sound insulation performance.
