CAD20-WP soundproofing wall insulation 

CAD20-WP  soundproofing wall insulation100% Recycled

CAD20-WP (Part Code A370) panel insulation is specifically designed to absorb and reduce airborne noise through party walls. It is extremely effective when applied to single skin walls such as breeze, brick or studwork partitioning. These panels are ideal for improving the soundproofing performance of domestic party walls and lightweight stud partitions. It is easy to install and can produce excellent results for a minimal 50mm of space.
The insulated wall shown in the detail at the bottom of this page had a sound insulation value of


which is generally an 8dB - 10dB improvement (around a halving of the noise) and complies with the requirements of the Approved Document E 2003

Please Note:
This product is not ideally suited for loud music and bass sounds coming through party walls.

Wall Preparation.

It is essential that there are no holes in the existing wall. The most common source of noise leakage is where the flooring and ceiling joists are fixed. The wall should be as airtight as is physically possible.

If any party walls to be treated are directly under the roof the loft must be checked to ensure that the dividing wall continues through to the roof. If it does not, the wall should be constructed up to the roof. Care must be taken to ensure an airtight seal exists between the roof and the wall. This is best achieved with flexible mastic sealant.

A further improvement in sound insulation can be gained by boarding out the loft with 22mm T&G Floor Grade Chipboard after 200mm fibreglass quilt installed.

Installation for Walls

The insulation is simply bonded onto the wall with our adhesive and the plasterboard is bonded to the panels in the same way.

Where neccessary, the insulation is easily cut with a sharp knife or jig-saw.

Once applied it should be left overnight for the adhesive to cure. It may be neccessary to support the insulation during this time.

When the insulation is securely stuck, two layers of 12.5mm plasterboard should be glued on top with the same adhesive.

A small gap should be left around the edges of the plasterboard to avoid bridging the resilient layer. This gap should be filled with flexible mastic sealant and a plaster skim coat applied to finish off the plasterboard.

Even greater noise reduction can be obtained if the treatment is applied to BOTH sides of the wall.

This product and method is not suitable for loud music and cinema noise coming through a wall.

acoustic flanking strip for perimeter isolation

This optional 45mm deep acoustic flanking strip is ideal for keeping the plasterboard from touching the floor/wall/ceiling. Any excess can be cut away before applying the acoustic sealant. In many instances it can be pulled out after the plasterboard adhesive has dried.
