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 the room, and the acoustic membrane on the back of the board adheres to the wall.
- Ensure the surface you are applying the panels to is in good condition, and 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 extend 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. Fix the panels using nine Hammer fixings per board. These fixings are suitable for most solid walls. Always check before the installation to ensure suitability. Screw the panels onto timber or metal studs with drywall screws.
- Use acoustic sealant between each panel as you butt 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.
- When reinstating electrical outlets, use acoustic putty pads inside recessed back boxes.
Finishing soundproof panels
- Taping and jointing -Apply joint tape (paper or mesh) over all joints. Use jointing compound to fill and feather out over the tape.
- Skim Plastering – Apply a thin coat of finish plaster (usually 2–3 mm thick) over the entire plasterboard surface.
- Plasterboard Direct Decoration (No Skim) – Tape and joint as usual. Sand and apply a sealer or mist coat. Paint or wallpaper directly onto the plasterboard.
Delivering soundproofing throughout the UK
Due to the nature of most of the materials we supply, orders are typically delivered on pallets.
All orders will be carefully wrapped, protected, and securely palletised to ensure they arrive in the best possible condition. Goods will be delivered as near to the property as possible. The drivers will not be able to carry orders into your property.
Deliveries are made between 8:00 a.m. and 6:00 p.m. Monday to Friday.
We charge a flat delivery rate of £60 plus VAT for most palletised deliveries. We do not charge per pallet, regardless of the number of pallets used to deliver your order.
Certain postcodes will incur a higher delivery charge than our standard rate, including those in Northern Ireland, Northern Scotland, and the Islands off the mainland.
Orders placed for items weighing less than 20kg will be sent via courier for £20 plus VAT.

FAQS
Soundproofing reduces the transmission of sound waves through walls. This is usually achieved by adding materials that either block or absorb sound. The main aim is to prevent sound from entering or leaving a room.
A soundproofing wall solution combines one or more of these elements to insulate the wall:
Add mass: Increasing mass or density in walls makes it more difficult for sound to pass through. High-mass soundproofing products include soundproof plasterboard, acoustic insulation, and soundproof membranes.
Improve sound absorption: Enhancing a wall’s sound-absorbing capacity helps decrease airborne noise. Materials such as acoustic insulation and membranes reduce resonance and vibration, thereby improving overall soundproofing.
Decoupling: Isolating or decoupling the existing wall diminishes direct sound transfer. Since sound travels through solid structures via vibration, using an independent wall or sound-isolation clips can lower sound transmission between structures.
- Mass-loaded vinyl (MLV): A dense, flexible material that blocks sound.
- Soundproof panels: High-density soundproofing boards that block sound.
- Acoustic insulation slabs: Help absorb sound within wall cavities.
- Decoupling clips: Sound-isolation clips that decouple the existing wall from the new wall, reducing vibration noise.
- Soundproof plasterboard: Denser than standard plasterboard, making it more effective at blocking airborne sound.
Yes! You can add materials like soundproof panels or acoustic wall systems directly to existing walls. These solutions don’t require major construction but can significantly reduce noise. By applying these types of solutions to your walls, you will minimise space loss in the room.
Recommended direct-to-wall soundproofing solutions, which don’t require removing the existing wall:
Silent Panel: Unmatched soundproofing performance of any soundproof board. Soundproof walls without compromising valuable living space with Noisestop Silent Panel.
AcoustiClip Direct System: The best direct-to-party wall system. The AcoustiClip Direct System features isolation clips, acoustic insulation, and soundproof boards for maximum protection against noisy neighbours.
Noisestop System 2: The thinnest of the party wall soundproofing systems, Noisestop System 2 combines acoustic insulation and soundproof panels.
Acoustic Panel: Slimmest direct-to-wall soundproofing panel. The Noisestop Acoustic Panel is ideal for soundproofing rooms with minimal space loss.
Yes! Low-frequency noises, such as bass or vibrations, can be more difficult to block. To reduce this, you need to use a technique called decoupling, which separates layers of the wall to prevent sound vibrations from travelling through it.
Decoupling isolation clips applied directly to the wall or a stud frame will reduce vibrations travelling through the wall’s structure. If space allows in the room, an independent soundproof wall will reduce sound transfer between walls.
The best wall soundproofing solutions for reducing these noises are the AcoustiClip Direct System or the AcoustiClip Stud System, as they minimise vibration transmission through walls.
Soundproofing can greatly reduce noise, but it’s unlikely to block 100% of sound. Low bass frequencies or very loud noises may still pass through, but the overall noise reduction can be significant. To maximise the benefits of your wall soundproofing, consider other areas of the building that might be weak spots and allow sound to pass. See our flanking noise answer below.
Common flanking noise paths.
- Ceilings and floors, joists with empty cavities
- Side walls that connect to the soundproofed wall
- Studs and framing inside the structure
- Doors and windows
- Electrical outlets, vents, and gaps
