Soundproof a Wall Using Wall Soundproofing Systems

Wall Soundproofing Using Wall Soundproof Systems

Step by step guide to soundproof a wall using wall soundproofing systems. This can be done by anyone competent at DIY, recommended installers or a local tradesperson. The systems are very simple to install and as long as materials are installed using these guidelines will offer high levels of sound reduction.

Prepare the wall by removing all items attached, such as cupboards, shelving, fireplaces etc. Then remove all skirting, coving, pipes and any electrical sockets and switches. If you are not fully conversant with electricity or plumbing it is best dealt with by a qualified tradesperson.

How to Stop Flanking Noise When Soundproofing a Wall

Check the wall area above the ceiling by removing floorboards to gain access within the cavity to ensure there are no gaps or holes. If there are any gaps or holes present, fill with a suitable material. For large areas we would recommend DFM acoustic insulation. For smaller areas a mortar mix or an acoustic sealant would be ideal. THIS IS A VERY IMPORTANT PART OF THE PROCESS TO REDUCE FLANKING NOISE.

How to Install Wall Soundproofing Kit System 1 & System 2

Attach timber battens of whatever depth needed to accommodate the Dense Fibre Matting or similar infill vertically onto the wall at between 400-600mm. This would be done right the way across the surface of the wall. The studs should be attached to the floor, ceiling and return walls, try to avoid fastening into the existing wall. If you can build the studs free standing from the wall this will improve the soundproofing performance. Once the battens are in place install the Dense Fibre Matting or equivalent between the battens ensuring a tight fit. Dense Fibre Matting can be easily cut with a hand saw. Be sure to wear a facemask if working in a confined area.

Once the entire wall has been covered with the Dense Fibre Matting you would then need to install the Soundbreaker Bars if they are being used as part of the system. The Soundbreaker Bars are installed with the pre-drilled part of the part to the bottom and fixed horizontally to the timber battens. The bars are spaced as 600mm centres, starting at the bottom of the wall 50mm up the wall from the floor. Make sure that you leave a gap of 5mm between the floors, walls and ceilings when installing the Soundbreakers Bars so that they are free from touching any surrounding surfaces.

Fix Acoustic Panels to Soundbreaker Bars or directly on to the Stud Frame

Once the Sound Breaker Bars are installed you would then need to install your choice of Acoustic Wall Panel. This could be the Noisestop1, the Noisestop1+, the Noisestop2 or the Noisestop2+. Starting at the bottom left hand corner of your wall, fix the first panel. The panels are screwed into the Sound Breaker Bar (if they are being used, if not screw directly into timber batten) through the wider corrugated part of the bar using standard dry wall screws/self tappers. Repeat this process across the whole area of the wall.

Apply Acoustic Sealant to the Edges of Every Panel

Before the panel is fixed into place, apply a large bead of acoustic sealant around the panel to seal the boards together. Repeat the process for the whole installation, wiping away any excess from the face of the panel.

Remember to cut the panels to size and shape before fixing or applying acoustic sealant.

Using the acoustic sealant fill all joints and gaps but keep a clean even surface over the whole area. We recommend a plaster skim finish. This is best achieved by a professional. The wall can then be brought up to a decorative state.

Once the work is complete electrical points, skirting and coving can be replaced. light weight objects can be put back onto the wall such as pictures and mirrors. Drilling into the wall should be kept to a minimum to avoid sound transfer.
