Opti 120 Acoustic Wall System

• High level of acoustic reduction
• Dampening matting to reduce noise in the existing structure
• Completely independent wall lining
• Multiple layers of acoustic mass
• Optimum acoustic insulation
• Deep void created to be completely isolated

M20 Rubber sheets are installed onto the existing wall. Use M20 contact adhesive to get initial grab. Install the M20 in a brickbond pattern. Use acoustic sealant if there are any gaps between the sheets and around the perimeter of the room. Use appropriate mechanical fixings to fix the M20 to the wall. Fischer hammer fixings and insulation washers are commonly used.

Leave a minimum of 25mm airgap off the M20 and install your independent wall lining. This can be timber or metal track and stud, use a minimum of 50mm stud. The deeper the stud and cavity the better performance at low frequency. Infill the stud with the appropriate depth of RWA45 insulation.

Fix Siniat dB Plasterboard (blue) to the newly formed stud. Again install in a brickbond pattern and seal any gaps with an acoustic sealant, and the perimeter of the wall. Install Tecsound SY100 to the face of the plasterboard. Cut your tecsound into manageable lengths. Installing the Tecsound is a 2 man job to  get it done well first time. You can hang it vertically (like heavy wallpaper!) or horizontally starting from the bottom and working up. Butt joint the Tecsound without and overlap. Ensure the entire wall is covered and seal any gaps and perimeter with acoustic sealant.

Over board the Tecsound with Siniat Fireline (pink) plasterboard 15mm. Fix through the Tecsound and dB Siniat board to find the studs. Seal the joints and the perimeter of the room. The wall is then ready to be finished. This can be wet plastered or using tape and joint method.
