This Direct to Stud Wall solution offers very good results when soundproofing stud walls and should meet Building Regulations provided that the original wall is well constructed and that flanking noise is not a major issue. However where space permits we would highly recommend the Decoupled Timber Stud Wall Soundproofing Solution which will provide even higher noise reduction through timber or metal stud walls.

27.5mm to 30mm

Brief Instructions: (have you considered Flanking Noise?)

1. Make existing wall sound by removing any loose material.

2. Bond or screw PhoneStar to the existing wall and butt the panels closely together. Do not leave any gaps between or around the PhoneStar layer. See Cutting and Taping PhoneStar.

3. Bond the plasterboard to the PhoneStar or screw through PhoneStar into the studs, being careful to stagger joints and leave a 5mm perimeter gap around the plasterboard at the floor, walls and ceiling. Optionally add a second layer of plasterboard for better results.

4. Seal 5mm perimeter gaps with flexible mastic or acoustic sealant.

5. Tape and seal all plasterboard joints and fill screw heads.

6. Fit skirting boards ensuring no contact with the floor – leave a 2mm gap.
