Guide to installing Wall System 2 to soundproof internal walls

Wall preparation

Before installing the new acoustic wall, you should remove all wall decorations, skirting boards, coving and picture rails and electrical outlets. Extend the electrical cable as required to reinstate the electrics once the work is complete.

Installing Wall System 2

Wall System 2 is one of the thinnest wall soundproofing systems available. This solution combines high-density soundproof products to reduce airborne sound through party walls. Wall System 2 requires battens fixed directly to the wall. Fitting Wall System 2 reduces good airborne sound levels and with space loss to the room of less than 50mm is one of the thinnest solutions for noisy neighbours.

Step 1.

Installing the frame

To ensure space loss to the room is kept to a minimum, fix the battens onto the wall being soundproofed. The 25mm frame should be fixed to the wall using a strong no nails adhesive or mechanically fixed with nails or screws. Always ensure the batten is well secured to the wall before commencing the installation.

Step 2.

Insulating the stud frame

Infill the stud frame with DFM acoustic insulation. Fill the cavity with acoustic insulation with no gaps between the insulation and the stud work.

You can cut acoustic insulation with a hand saw or an old bread knife. Measure the opening between the studs and cut the insulation approximately 5mm wider. Cutting the slabs wider than the opening will mean the slabs will friction fit between the studs. You shouldn’t need to use fixing to hold the slabs in place; if necessary, you can fasten a screw or nail into the side of the stud to hold the insulation in place.

Step 3.

Fitting the soundproof panels

NOTE: Fit the boards with the blue face of the acoustic plasterboard facing into the room—the mass-loaded barrier mat on the back of the board into the wall.

The soundproof panels are fastened to the soundbreaker bars using drywall or universal screws. You can not nail into the bars. You will not need to drill the boards before you attach them. Screw straight through the panel into the wide corrugated flange of the bar. You should be able to use 15 screws per full-size panel 1200mm x 1200mm. Fasten into the three bars behind the boards with five screws per bar. Do not over tighten the screws. They should be flush or just below the surface of the plasterboard face.

 When you reach the edges of the wall, you will need to cut the soundproof boards. Cut the boards with a Stanley knife, hand saw circular saws, or a jigsaw.

It is essential to ensure that every edge of the panels is well fitted and sealed. Do not leave gaps between the boards; ensure they are butted together. Use AC50 acoustic sealant along the edges of each panel as you install them. Once you’ve fitted the first board, run a bead of the acoustic sealant along the edge and then install the next. Once all the panels have been fitted check the wall making sure you fill small gaps with the acoustic sealant.

Step 4.

Finishing you wall

All our soundproof panels are manufactured using a 12.5mm acoustic plasterboard with tapered edges; you can finish the boards in two different ways. You can plaster skim straight onto the face of the panels using multi skim thin coat plaster. Alternatively, you can also tape the tapered edge of the panel, fil and sand them before decorating.

Reinstate your wall furniture as necessary. You can reinstate electrical points back into the wall. To avoid cutting out sections of the wall, we would recommend surface mounted sockets. If you are using recessed back boxes, use the acoustic putty pads to ensure the soundproofing integrity of the wall.
