SOUND INSULATIONFIRE DOOR

Designed based on acoustic principles, adopting double-layersteel plate (or stainless steel) composite structure, with doorthickness of 50-75mm and filled with porous fireproofsound-absorbing materials.Door frame and leaf are made of cold-rolled steel, with thinsteel plate (stainless steel) on the surface, and filled withfireproof sound-absorbing materials to form high-dampingcharacteristics.Double elastic stops (sealing gaskets) are set around the doorframe to eliminate sound leakage design.

Sound Insulation Performance: Significant sound insulationfor 315-4000HZ mid low frequency noise, Sound insulation35-40dB (A)Fire Resistance Performance: Temperature resistance of 300C-950C, meeting fire protection grade requirementsDurability: Can bear aerodynamic load of 100ON/m2, withopening service life >12.000 timesNationaauthoritative department’s sound insulation testreport can be provided

Specifications and sound insulation performance can becustomized according to sound insulation grade, installationspace and fire protection gradeSurface can be equipped with advanced decorative materialssuch as wood imitation and leather without affecting thesound insulation
