M20AD Soundproofing for Walls

Technical Specification

Panel Size                                     :     nom. 1m x 1m x 20mm +/- 5%

Density                                         :     nom. 800kg/m3

Composition                                   :     Recycled rubber and binders

Thermal conductivity coefficient (λ)   :     EN1267    W/mK 0.12

Soundproofing performance               :     DnT,w (C;Ctr) = 56 (-3;-8)dB

Because this is a recycled product, sometimes foreign objects may be incorporated into the rubber.  As long as these do not penetrate from one side of the panel to the other it will have little effect on the soundproofing properties once installed.

See illustrations below to see how M20AD Soundproofing can improve the sound insulation of a stud partition.

The estimated soundproofing performance of the stud partitions shown above are for partitions with no holes and all joints properly sealed. The sound insulation performance indicated may vary from site to site and should only be used as a guide.

The soundproofed wall shown in the detail below had a sound insulation value of 48dB DnT,W+Ctr which is approx. an 87% reduction in sound transmission and complies with the requirements of the latest Approved Document E Building Regulations. It is therefore, ideal for soundproofing walls, separating stairs and hallways where space is at a premium.
