Description
Noisestop 1 Plus Panel is a high-mass, dense acoustic soundproof panel that will insulate ceilings and walls acoustically. It is designed to block the transmission of sound effectively. Noisestop 1+ Panel is instrumental in creating robust ceilings and wall linings. A premium, slim, high-mass acoustic board suitable for ceilings and walls. Outperforming standard ‘soundproof’ plasterboards, its versatility in installation makes it an ideal standout choice. This versatile panel combines mass and sound absorption in all our soundproofing wall and ceiling systems. Comprising a 10kg mass loaded vinyl membrane pre-bonded to a 12.5mm acoustic plasterboard eliminates the need for separate soundproof membranes. It significantly bolsters the sound insulation performance of walls and ceilings within soundproof systems.

Performance Data

Improvement DnT,w
Noise reduction with treatment 4dB
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.
Fitting Noisestop 1 Plus Panels
NOTE: When the acoustic plasterboard panel is installed, the plasterboard layer faces into the room, and the acoustic membrane on the back of the board goes onto the wall or ceiling. This panel is best suited for use with AcoustiClips, soundbreaker bars or timber and metal stud frames to form an acoustic system for walls and ceilings.
The Noisestop 1 Plus Panel works best when installed as part of a complete system for walls or ceilings.
- 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, coving and extend electrical outlets, wall linings such as wallpaper do not need to be removed before the installation.
- Fix the panels to acoustic hangers, stud frames or ceiling joists using standard dry-wall screws. You should use Hammer Fixings, nine per board to fit the boards directly onto solid walls; alternatively, use the Smart Tack adhesive for flat finished walls, one tin per five boards.
- Leave a 2-3mm gap around the perimeter of the wall to reduce flanking sound transmission, apply an acoustic sealant to fill the gap once the installation is complete.
- Cut the panels using a hand saw or circular saw.
- Skim plaster or tape and fill the tapered edge.
- Upon completion of the soundproofing, reinstate the skirting and coving.
- If you are reinstating electrical outlets, use acoustic putty pads inside recessed back boxes.
NOTE ON FLANKING SOUND – Before installing any soundproofing system, it is important to consider any flanking paths for the sound. These are areas around the wall where sound will bypass the soundproofing and enter the room. The most common flanking path for sounds would be above or below the wall, this would be through a floor or ceiling cavity. If these areas are constructed from timber joists, you should consider filling the cavities above or below the area with DFM acoustic insulation to stop potential flanking noise.

Essential Soundproofing Rules
Achieve the very best wall soundproofing results by following these essential soundproofing rules. These are adding mass/density to the area, isolating or decoupling the new structure from the existing and increasing sound absorption. These rules of soundproofing apply whether you are attempting to soundproof a stud wall or solid brick walls. Increasing mass makes it harder for the sound to transfer. The variety of high-mass products will block a great range of sounds. Decoupling the structure will reduce sound as it vibrates through a solid structure. Increasing absorption allows the wall to absorb the sound energy. These soundproofing principles are built into the design and specification of our wall soundproofing products and systems.
Mass/Density
Adding mass/density to an area blocks sound transfer. Using materials with different densities will reduce a greater range of frequencies.
Isolation
Creating isolation or decoupling the existing structure from the new enhances sound insulation.
Absorption
Increase sound absorption with materials that absorb sound waves and reduce the energy that carries the sound.
Soundproofing Walls FAQs
The best way to soundproof a wall is to block the sound transmission from one room to another. The most effective methods to soundproof walls are:
Add mass: increasing the density of the wall by adding mass. Use mass loaded vinyl, soundproof plasterboards and high density acoustic insulation to enhance the sound insulation.
Decoupling: By isolating the existing structure from the new wall, you will reduce the vibration sound that transmits through the wall. The AcoustiClip system is the best method of decoupling walls and ceilings.
Sound absorption: The walls ability to absorb sound waves is crucial in noise reduction. Product combinations work best for overall sound absorption or sound dampening. Acoustic insulation and soundproof membranes will dampen and absorb sound waves as they come into contact with them.
All our solutions are designed to incorporate as many of these as possible.
The best way to soundproof party walls and internal stud walls is to use a soundproof system that combines materials to offer the highest level of noise reduction.
We recommend the AcosutClip System to soundproof any wall. The systems incorporate all the soundproofing products to ensure exceptional noise reduction against airborne and vibration noise. Provided with the systems are the AcoustiClip, AcoustiChannel, acoustic insulation, Noisestop 1+ Panels, acoustic plasterboard 15mm and acoustic sealants.
We have the AcoustiClip Direct System, our most popular solution for party walls. If you require soundproofing for excessively noisy neighbours or studios, we have the AcoustiClip Solid Wall System. The AcoustiClip Stud Wall System will restore privacy within your home for internal stud partitions.
Our slimmest wall soundproofing solutions are the Noisestop Sielnt Panel or Wall System 2.
Silent Panel 30mm: The Noisestop Silent offers the best acoustic performance of wall soundproofing panels. At only 30mm thick, it can be used to soundproof walls in the tightest of spaces.
Wall System 2: Our thinnest solution combining soundproofing materials is Wall System 2. If you have limited space and require maximum sound insulation this is our recommended solution.
All our products and systems for walls and ceilings are supplied with acoustic plasterboard as the final finish. This type of plasterboard can be finished in the same way as standard plasterboards.
The acoustic plasterboards have a tapered edge which allows for taping and jointing if you want to avoid having them plastered.
Yes, you can reinstate electrical outlets into any of our soundproofing solutions.
We can provide acoustic putty pads for the electrical back boxes for single and double sockets.
You can use your wall as any other wall when attaching lightweight items.
For heavier objects like wall-mounted TVs, you must secure them to the structural wall behind the soundproofing. Direct sound transmission through these fixings would typically be minimised due to the mass and absorption of the soundproof panels.
