An acoustic carpet underlay made from a rubber base and a high grade felt top layer, Acoustic Carpet Underlay is designed for installation directly beneath carpets to give superior reduction in impact noise transmission through to the floors below. The weight of this underlay is nom. 2.5Kg/m² which equates 72oz/yd², this is an extremely heavy, high quality underlay which will also help absorb a small amount of higher frequency airbourne noise. This product is not suitable for 'airborne' noise reduction. If airborne noise is the problem then you need to look at our other solutions involving Acoustic Mineral Wool, Soundproofing Mats and/or Quietfloor Slabs. It is suitable for all types of floor surfaces including wood, concrete, asphalt, and is particularly recommended on uneven floors. |
