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. Decibels explained.
NOTE: When the panel is installed, the plasterboard layer faces into the room, and the acoustic membrane on the back of the board goes onto the wall.
- Ensure the surface you are applying the panels is in good condition, make good any remedial work to the existing wall to ensure it is flat and secure before you attach the panels.
- Remove skirting boards and coving and extending electrical outlets; these can be reinstated once the work is complete.
- Begin the installation by installing the bottom row of boards. Leave a 2-3mm gap between the floor and the boards using 2-3mm packers or an equivalent to support the panels.
- Apply the Noisestop Acoustic Panel to the walls using Hammer Fixings or the Smart Tack Adhesive. We only advise using the adhesive on flat walls; approximately one tin will fix five panels. Fix the panels using nine hammer fixings per board if the wall is uneven or in poor condition. Screw the panels onto timber or metal studs with drywall screws.
- Use acoustic sealant between each panel as you put them together.
- Leave a 2-3mm gap around the wall’s perimeter to reduce flanking sound transmission, and apply an acoustic sealant to fill the gap once the installation is complete.
- Cut the panels using a hand saw or a circular saw.
- Skim plaster or tape and fill the tapered edges.
- Upon completion of the soundproofing, reinstate the skirting and coving.
- If you are reinstating electrical outlets, use acoustic putty pads inside recessed back boxes.

Soundproof panels FAQS
Soundproof panels are specialised acoustic panels designed to reduce sound transmission between spaces. They are typically made of dense, sound-absorbing materials such as soundproof plasterboard, mass-loaded vinyl and acoustic foams, which help to block and absorb sound waves.
No. Soundproof panels significantly reduce sound transmission, but achieving higher levels of soundproofing requires combining various methods and materials (such as sound isolation clips, resilient channels and acoustic insulation). See our Soundproofing Systems for more information when higher levels of sound insulation are required.
Yes, many soundproof panels are designed for easy DIY installation. They are typically installed with screws or adhesives depending on the type of panel and the surface they are being applied. Products frequently used with soundproof panels include the following.
- Acoustic sealants – seal the edges and the perimeter of the wall to keep the area airtight.
- Hammer fixings – Secure sound panels to most solid walls using a hammer fixing. Other fixings, such as drywall screws, are used for different backgrounds, such as stud work or metal furring channels.
Most soundproof panels have an outer face of plasterboard, which allows for finishing, such as a plaster skim like a standard plasterboard. Our soundproofing boards have a tapered edge that enables them to be taped and filled as an alternative to plastering. Decorating straight onto the panel’s surface with paint or wallpaper is possible.
Once the soundproofing has been installed, the electrical outlets can be reinstated. To ensure acoustic integrity, we recommend using an acoustic putty pad inside the electrical back box.
You can attach things such as shelves and mirrors over soundproof panels. If the wall behind the panel is a solid wall, use a suitable fixing that connects to the wall behind the panel; if it’s a stud wall, use a suitable stud wall plug.
