Where Multi-use application on walls, floors and ceilings. Used as a standalone for the damping of vibration in metal structures and use in many of our acoustic systems.

Tecsound is a flexible, easy to handle and high performing acoustic matting for all your soundproofing needs. it is a feature in many of our acoustic systems and is suited for timber and concrete structures with particular focus on the 'muting' vibration in metal structures. Learn more below.

There are long-term health effects that are now being connected with the exposure to noise, maintaining health and wellbeing is important in both homes and workplaces. With this in mind, it is important to find the right solution, one that can bring peace and quiet to your environment.

Tecsound S100 is a visco-elastic membrane, and this means it is both a viscous material, part way between a solid and a liquid, having elastic properties, meaning that it returns to its original form when stress is within its limits, like pulling an elastic band, if you pull it too hard it will break.

Tecsounds sweet spot for damping or ‘muting’ vibration does not often go into these ‘stresses’ in the majority of projects that need control over vibration.


  • 4m x 1.2m x 5mm (4.8m2).
  • A visco-elastic membrane for damping vibration.
  • High mass for resisting airborne noise.
  • Self-adhesive application to a wide range of surfaces.
  • Easy to cut to size

For soundproofing, these are both effective for the damping of vibration, and because of its high mass, will reduce airborne noise too. To achieve the best possible solution on soundproofing projects, you will need to incorporate them into ‘Systems’, and it is here you will find Tecsound in a range of options. Each offers ways of increasing acoustic performance, for example, by fitting them alongside acoustic cradles to create a fully floating floor, by adding them to joist structures alongside sound insulation for a vast improvement for airborne and impact noise or use in concrete buildings as a standalone for impact reduction.

Tecsound S100 is a single ply material, one that is primarily designed to be installed within acoustic systems, or used to be directly applied to metal cladding to dampen vibration. Our acoustic test data and performance is based on an acoustic curtain, where Tecsound separates two rooms and then measures its performance. When factored into a ‘System’ this will change as you cannot add dB levels together, you can learn more on our ‘Science of Soundproofing’ page.

Tecsound S100 is a 5mm thick, visco-elastic membrane that is accompanied with a self-adhesive backing to make direct application simple and straightforward without the need for mechanical fixings, tacking or any additional adhesives. Visco (viscous, a thick and often sticky consistency) elastic (when stretched will often return to its original state) is a flexible, dense and easy to cut product that sits between both of these two properties turning sound energy into heat, dissipating the sound energy. Essentially this highly versatile sound proofing material is applicable for floors, walls and ceilings, for cinema rooms, for sound proofing your home or constructing composite acoustic systems along with our MuteClip® for optimal performance.
Reducing vibration in structures, especially metal structures, is one of Tecsound’s most astounding features, and it will be a change you notice immediately with direct application. The self-adhesive backing stay’s in contact with the surface – which is why we opt for self-adhesive. Energy from the vibration conducted into the Tecsound S100 and dissipated vastly dampening the resonance and removing the extended release of ringing heard in metal structures. Tecsound is used to reduce resonance between acoustic plasterboard and improve airborne performance, it is the most effective soundproofing systems that feature varying densities and material properties to break down frequencies in different ways, Paths of soundwaves move differently through different materials, some help to slow down its trajectory, others help to block it through mass.
Vibration travels significant distances in metal structures, and metal is, after all, a conductor of energy. For example, if you tap on a metal structure, you will hear it ring, think of playing the steel drum or a triangle, then tap on a wooden block. Which one has a longer decay time? The metal, right? Tecsound S100 is perfect for the use of sound proofing metal ducting against vibration, and this would often not require complete coverage of the ducting and maybe only in small parts. In cases where the metal ducting leaks sound, we will aim to wrap the ducting to reduce sound transmission fully.
Tecsound S100 temperature range is between -20°C to 60°C, anything above and below these could compromise performance with direct contact with the pipes, it is best to create a form of acoustic boxing around these pipes and apply Tecsound to the acoustic plasterboard boxing, something you will want to discuss with a plumbing specialist to be sure it is compatible.
Waste moving through waste pipes can make for an uncomfortable environment, especially if they lack any acoustic treatment. Tecsound S100 can be used to soundproof waste flues, and you should aim to box in the waste pipe to improve the sound proofing performance. As an alternative, our MuteWrap™ works exceptionally well against sound proofing waste piping.
Bathrooms and wet rooms contain high amounts of vapour and moisture, which in time will begin to degrade the Tecsound’s adhesive qualities and possibly damage the elasticity over time. We recommend to use a Vapour or Moisture plasterboard protecting it from any exposure, and it is most common that Moisture Board is used internally in bathrooms to preserve the soundproofing materials beyond it. Vapour Boards concern primarily external walls, so when damp is expected in any of these areas, you will want to discuss the use of soundproof materials with a damp specialist in these placements.
Tecsound S100, when hung as a curtain reduces sound at an average of 31dB – what this means is that if you place a sound measuring device at one end of the room and another device playing audio at the other end (usually in a controlled environment and to specific level of sound) it will reduce it by this amount. Decibel reductions cannot be added together, so when using Tecsound S100 in a sound insulating system, applied directly to a wall or within one of our MuteClip® Systems, these results will differ and is not always possible to determine what level of soundproofing the Tecsound will provide in these composites.

Installation Guide

Tecsound S100 is a self-adhesive material, and when Tecsound arrives, you will find two sheets attached as you roll it out. One of them is a polypropylene fleece that helps increase the tear strength of the Tecsound, do not tear this off, the other is the removable protective covering to expose the adhesive, this is easy to peel off compared to the protective fleece. If you are unsure, peel a little off the corner to reveal the adhesive side.

You will want to install Tecsound over the joins of acoustic plasterboard and not meet them up to create an airtight system, the lesser joins, the better. With this in mind, when cutting Tecsound you will want to keep them as generous as possible without being challenging to manage, it is easy to cut with a new Stanley blade, and you will want to have at least two people during the installation.
