Walls – Direct to
*Please Note: PhoneStar was previously branded as Phonewell
This Direct to Wall solution offers good results when soundproofing party walls. However where space permits consider the deeper decoupled wall solution or decoupled and battened wall solution particularly if you want to reduce noise from noisy neighbours. These options will provide significantly higher noise reduction through the wall because they combine high mass with decoupling.
DIRECT to MASONRY WALL SOLUTION: 27.5mm to 30mm
Good performance for the absolute minimal loss of living space, but if at all possible we would strongly recommend the decoupled wall options. However this option is ideal as a remedial solution to meet Building Regulations where only a small improvement is required. It can also be used where the workable space is extremely limited.

Brief Instructions: (have you considered Flanking Noise?)
1. Make existing wall sound by removing any loose material.
2. Bond PhoneStar to existing wall with a quick setting adhesive foam and butt the panels closely together. Do not leave any gaps between or around the PhoneStar layer. See Cutting and Taping PhoneStar.
3. Bond plasterboard to PhoneStar with a quick setting adhesive foam, being careful to stagger joints and leave a 5mm perimeter gap around the plasterboard at the floor, walls and ceiling. A second layer of plasterboard can optionally be added on.
4. Secure plasterboard to wall with a few secondary mechanical hammer fixings, do not over-tighten.
5. Seal 5mm perimeter gaps with flexible mastic or acoustic sealant.
6. Tape and seal all plasterboard joints and fill screw heads.
7. Fit skirting boards ensuring no contact with the floor – leave a 2mm gap.
