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.

Noise pollution is one the leading problems of the modern world today, and it has a profound and detrimental effect on both your health and wellbeing, it is even more critical now to seek a solution that will give you a tranquil space, ones that you can live in peacefully, and work in without distraction.

Tecsound SY70 (Half Roll) 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.


  • 5.05m x 1.22m x 4mm (6.16m2).
  • 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 SY70 is a single ply material, one that is primarily designed to be installed into 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.

The subjective nature of noise means your sensitivity to a specific sound or event will differ from others. These noises could be from disruption from footsteps above, or conversation from all directions, or even the loud, tin-like sound from the rain in contact with metal sheeting. Acoustic issues will vary for homes or workplaces, but it is our Tecsound SY70 that offers improvements in our acoustic systems, look for our ‘Pro’ and ‘Plus’ systems as these feature the use of Tecsound.

Tecsound SY70 is a 4mm thick, visco-elastic membrane that is accompanied with a self-adhesive backing to make direct application easier without the need for mechanical fixings, tacking or additional adhesives. Visco (viscous, a thick and often sticky consistency) elastic (when stretched will often return to its original state) is a malleable, dense and easy to cut product that sits between both its mechanical components. These make it suitable for reducing vibration and airborne noise issues as the two properties combined help to dissipate energy, meaning that when sound or vibration comes into contact with it, this sound energy turns into heat.

Essentially this highly versatile sound proofing material is applicable for floors, walls and ceilings, for cinema rooms, for sound proofing a bedroom or constructing composite acoustic systems for maximum performance.

One of Tecsound’s most astounding qualities is its reduction of vibration, and it will be a change you notice immediately upon direct application. The self-adhesive backing remains in constant and level contact with the surface it is applied to, which is why we opt for self-adhesive. Energy from any vibration conducted, especially from metal structures, is transferred into the Tecsound SY70, dissipated and results in a dampening of the resonance and removal of extended release of ringing often heard in metal structures.

Tecsound is often used between acoustic plasterboard to provide additional sound proofing properties, and the aim is to provide different densities and material composites to break down sound in different ways.

Vibration travels significant distances in metal structures, metal is, after all, a conductor of energy – and this includes sound energy. If you tap on a metal structure, you will often hear it ring out – think of playing the steel drum or a triangle, then tap on a wooden block – which one has a longer decay time? Tecsound SY70 is perfect for the use of sound proofing metal ducting against vibration; 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.
Tecsound SY70 temperature range is between -20°C to 60°C, anything above and below these could compromise its stability and acoustic performance with direct contact – it is best to create a form of boxing around these pipes if noise can be heard from them and apply Tecsound to the acoustic plasterboard boxing. You will want to discuss these options with a registered plumbing expert to make sure it is suitable for use.

Tec sound SY70 can be used to soundproof waste flues, where often waste can be heard travelling down or across them which can be a highly uncomfortable situation when noises associated with these are heard, you should aim to box in the waste pipe if possible to improve results.

As an alternative, our MuteWrap™ works exceptionally well against sound proofing waste flues.

Bathrooms and wet rooms contain high amounts of vapour and moisture, which in time will begin to degrade Tecsound’s adhesive qualities and possibly damage it’s elasticity over time if it is exposed. Professionals generally recommend that Moisture Board is used internally in bathrooms to protect any sound proofing materials behind it and the use of Vapour Boards when concerning proximity to external walls – you will want to discuss the use of acoustic materials with a damp specialist when you are fitting into these areas.
Tecsound SY70, when hung as a curtain reduces sound has an average of 28dB – what this means is that if you place a sound measuring device at one end of the room and another device playing sound at the other end (usually in a controlled environment and to specific level of sound) it will reduce it by this amount. You cannot add decibels together, so when using Tecsound SY70 in a sound proofing 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 sound proofing the Tecsound will provide in these composites.

Installation Guide

Tecsound SY70 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.
