This soundproofing for wall insulation is designed to absorb and reduce the amount of airborne noise which penetrates poorly insulated party walls. Easy to fit, this 20mm thick insulation is simply glued to the existing wall with two layers of 12.5mm plasterboard bonded on top and is an easy solution if you have a noisy neighbor.
The Insulated wall shown in the detail on the right of this page had a sound insulation value of 48dB DnT,W+Ctr which is over a 300% improvement and complies with the requirements of the Approved Document E 2003
