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

Tecsound SY70

Tecsound SY70 is a wonder material in the soundproofing world. If you are soundproofing a wall or ceiling, Tecsound can perform a vital role in reducing both impact and airborne noise.

Tecsound is a viscoelastic membrane that is excellent at absorbing sound vibrations. Its high mass means it performs well at reducing airborne noise. Tecsound SY70 is self-adhesive meaning it can be rolled out on walls and ceilings for simple installation.

Tecsound is best used as part of a ‘soundproofing system’ in these systems we pair Tecsound with complementary soundproofing products to develop the most effective soundproof partitions that take up the least possible space.

Self Adhesive Tecsound

The self-adhesive coating makes installing Tecsound much easier. We recommend cutting your roll down to manageable sizes with a utility knife. Then ideally two people can roll it up the wall.

Vibration dampening

One of the most remarkable features of this product is its ability to dampen vibration on metal structures. Vibration and resonance are noticeably dissipated with Tecsound.

Impact Noise

Reduces airborne and impact noise

Most soundproofing materials can only reduce impact or airborne noise but due to its unique properties, Tecsound is effective against both.

Mould, moisture and fungus resistant

Tecsound does offer some mould, moisture, and fungus-resistant properties.

  • 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 need 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 need to keep the cuts as generous as possible without being challenging to manage. It is easy to cut with a new Stanley blade and you should have at least two people during the installation.

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 soundproofing 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.

Bathrooms and wet rooms contain high amounts of vapour and moisture, which will eventually degrade the Tecsound’s adhesive qualities and possibly damage the elasticity over time. We recommend using a Vapour or Moisture plasterboard to protect it from any exposure. It is most common that Moisture Board is used internally in bathrooms to preserve the soundproofing materials beyond it. Vapour Boards primarily concern external walls, so when dampness is expected in any of these areas, you need to discuss the use of soundproof materials with a damp specialist in these placements.

Tecsound SY70 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 should discuss with a plumbing specialist to be sure it is compatible.

Waste moving through waste pipes can make for an uncomfortable environment, especially if it lacks acoustic treatment. Tecsound SY70 can be used to soundproof waste flues, and you should aim to box in the waste pipe to improve the soundproofing performance.

As an alternative, our Tecsound FT 55 AL works exceptionally well against soundproofing waste piping.

Tecsound is a viscoelastic membrane that is excellent at absorbing sound vibrations. Its high mass means it performs well at reducing airborne noise. Tecsound is self-adhesive meaning it can be rolled out on walls and ceilings for simple installation.

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 stays in contact with the surface – which is why we opt for self-adhesive. Energy from the vibration was conducted into the Tecsound SY70 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.

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.
