M20AD is a recycled rubber, high density sound blocking and sound absorbing product that is ideal to reduce noise through party walls and is a product that can easily be installed by and DIY competent person or local handyman.  The product is designed to help block and absorb airborne noise through lightweight stud and single skin masonry walls with the minimum increase in the overall thickness of the wall.  It is the best and one of the easiest solutions to reduce noise nuisance from neighbours and also to help contain noise generated in your own home.  No mechanical fixings are necessary because the product along with two thicknesses of 15mm acoustic plasterboard are bonded using our special sprayable contact adhesive.

M20AD can also be used to soundproof separating walls from stairs and common areas in flats to help bring them into compliance with Part E for the control of airborne noise through walls.

The drawing below shows how M20AD and acoustic plasterboard are applied to a masonry wall which is the same if fitted to a stud wall.  When fitted to a single skin masonry wall as shown below, independent testing showed the wall had a sound insulation value of 48dB DnT,W+Ctr which exceeds both the 43dB change of use Part E value and also the 45dB new build requirement.

Note:  Due to the limited thickness of this sound insulation for walls, it will only reduce the intensity of normal noise levels that would not normally be expected to be heard such as the radio or normal speech.  Music being played loudly, neighbours shouting or bass noise will always be heard but will no longer be as loud on your side of the wall.

Flanking noise around a party wall can also be a problem and should be addressed before upgrading the wall itself.  More information on how to do this can be seen in our article Soundproofing Walls.   Installation of this system either by DIY or outside help, the product should be installed in accordance with our instructions.

Due to the fact that M20AD acoustic panels are produced from recycled vehicle tyres a ‘rubbery’ smell may be noticed.  Although not harmful, if the smell is still evident a few days after the installation of the system including the plasterboard, the plasterboard can be sealed with a primer sealer that has been recommended to us by a past custoemr.  The following link will take you to more information on this  http://www.zinsseruk.com/wp-content/uploads/2012/05/B-I-N-TDS.pd
