Untreated brick wall DnT,w

Single skin 100mm brick wall 38db

Wall System 2 applied 54dB

Improvement DnT,w

Noise reduction with treatment 16dB

Note: Every 10 decibels(dB) reduction in noise level is roughly perceived as a halving of the perceived loudness. So, for instance, if you have a sound that measures 70dB and it decreases to 60dB, it would sound about half as loud to the human ear.

• If a stud frame is not already in place, install one. The stud cavity must be at least 25mm deep to accommodate the acoustic insulation. The frame can be installed directly on the party wall to reduce space loss.
• Space studs at 600mm centres to ensure you catch the edge of the 1200mm x 1200mm Noisestop 1 plus Panel.
• Fill inside the cavity between each stud with the 25mm DFM acoustic insulation slabs. Ensure the slabs are packed tightly between the studs.
• Attach the Noisestop 1 Plus Panel to the stud frame with 25mm self-drill drywall screws. The boards should butt together. Use acoustic sealant between the edges of the panels to form an airtight seal. Leave a 2-3mm gap around the wall’s perimeter to avoid noise transfer. Apply a bead of acoustic sealant around the perimeter of the wall.
• Finish the wall as you would standard plasterboard, either plaster skim, tape and fill the tapered edge, paint or wallpaper.
• If you are reinstating electrical outlets, use acoustic putty pads inside the back boxes.
