Tecsound SY70 is a self-adhesive, thin and high performing acoustic membrane to reduce airborne noise and vibration.

This product is labelled in our Essential Soundproofing Collection, which takes our most popular products in soundproofing walls, floors and ceilings to help you review what other customers are rating highly for noise insulation. Call us on 01937 588 226 if you would like further assistance with selecting the best products for your project.


Tecsound SY70 is a self-adhesive, visco-elastic membrane used to attenuate airborne noise with fantastic results. It can be applied directly to walls, floors and ceilings as well as applying directly to metal work to significantly reduce vibration within a structure.

When soundproofing walls, floors and ceiling you will want to consider the use of a highly effective acoustic system to retain the best results for both airborne and impact noise. Seperation is a key factor when noise levels are excessive this is to reduce the points of contact with the structure. Mass is another key factor in which the increase of this helps to resist airborne noise. 

The best performing systems and products are when they are made up of different materials with different densities and with additional flexible properties to break down the soundwave as it passes through a partition - this is where Tecsound is an ideal addition to a system. Our MuteClip® System is a great place to start for soundproofing walls and ceilings.

Tecsound SY70 Information

  • 3.5mm x 5.05m x 1.22m (6.16m2)
  • Suitable for attenuating both airborne noise and vibration on a large array of surfaces
  • Best used within MuteClip® System between two layers of high density acoustic plasterboard to dampen resonance between boards and to attenuate airborne noise
  • Surfaces will want to be as clean and dust free as possible for the self-adhesive to remain in contact
  • Very flexible and adaptable material

Interesting Fact

SY broken down from Spanish means 'sintética insonorizante autoadhesiv' synthetic soundproofing self adhesive; (S) and 'Yeso' roughly translates to the size of Gypsum Plasterboard in Spain (Y).

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 direct fixing, 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 it’s mechanical components, this makes 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 is turned into heat.

Essentially this highly adaptable 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 it’s 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 in to the Tecsound SY70, dissipated and results in a dampening of the resonance and removal of long release of ringing often heard in metal structures.

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

Vibration travels great distances in metal structures, metal is after all a conductor of energy - and this of course includes sound energy. If you tap on a metal structure you will often here it ring out - think of playing a steel drum or a triangle, then tap 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 it’s 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. Do 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. It is often recommended that Moisture Board is used internally in bathrooms to protect any sound proofing materials behind it and the use of Vapour Boards when concerning close proximity to external walls - you will want to discuss the use of acoustic materials with a damp specialist when they are to be fitted in these areas.

Tecsound SY70, when hung as a curtain reduces sound as 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 would reduce it by this amount. Decibel reductions cannot be added 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.
