SOUNDREDUCING MAT FRESH dB, 290x300x8 mm

Sound-dampening mat 290x300 mm, thickness 8 mm. Designed to replace the Fresh wall vent's Ø98/102 mm module pipe. Manufactured from cellular foam, cuttable to exact dimensions. One sound-dampening mat reduces external noise coming through the vent by approximately 2-3 dBA depending on vent type. Effective sound attenuation is achieved by installing two layers of sound-dampening mats in the penetration opening, but the reduction in replacement air volume should be taken into account.
