Tecsound SY70 is a highly versatile soundproofing membrane. It can be used in various types of construction that require a thin, yet effective barrier to reduce airborne and vibration sounds.
The self-adhesive Tecsound sheets are suitable for most wall and ceiling surfaces. One of the main areas of use for Tecsound is between sheets of plasterboard. The viscoelastic nature and high mass/density of the product ensure vibration and airborne sounds are significantly reduced when applied to the plasterboard. Use Tecsound directly onto metalwork to minimise structural vibration.

Tecsound SY70 Applications
• Increases airborne noise insulation on partition walls with low surface mass (stud walls and party walls)
• Soundproofing against airborne noise in ceilings and lightweight roofs
• Reduction of impact noise in laminated floors
• Damping of noise caused by weather such as rain and hail in lightweight roofs
• Combined with sound-absorbent materials, it offers solutions with high acoustic performances
• Its applications in the industrial field cover from the soundproofing of cabins to the acoustic insulation of machine-rooms, cowling of engines, gutter pipes, sound-damping of metal sheets, etc
Installing Tecsound SY70
- Tecsound SY is mainly applied between two plasterboard panels
- The membrane adheres with the self-adhesive underside to the first plasterboard to which the second plasterboard is attached
To prevent thickening, the membrane is placed without overlap (only butt joint). Care must be taken to ensure that the seams fit tightly and that there are no openings
Tecsound SY can also be used in lightweight roofs. Install the membrane with the polyethene film on top and overlap of at least 50 mm. In the case of profiled steel deck, the membrane must be placed transversely to the profile. Make sure that there are no openings as these will have a negative effect on the noise reduction capacity.

Frequently Bought Together
Make sure you are getting the right soundproofing for your needs. Understanding the most common types of noise and how to stop them will help you decide the right solution.
Different Types of Sound
- Airborne sounds – Conversation, TV noise and radios are examples of airborne sound. The best way to stop airborne sounds is to add mass/density to the walls or ceilings.
- Impact/vibration sounds – Footfall and moving furniture across a floor are examples of impact sounds. The best way to reduce these sounds is to create separation.
In summary, the best way to reduce airborne sounds is by increasing the mass of the area you would like to soundproof. Reducing impact/vibration sounds is achieved by creating separation within the structure.
Reducing Impact and Airborne Sounds
By following some of these steps, you will ensure you get the best level of soundproofing for your room.
- Mass/Density – Increasing the mass and density of the area you are soundproofing will block airborne sounds from transferring between rooms. You will increase the mass of walls and ceilings using materials such as soundproof panels or high-density acoustic insulation slabs.
- Separation – Incorporating separation within the structure will reduce vibration and impact sounds transferring between rooms. Achieve separation by building independent stud walls and ceilings. If you don’t have the space in the room, you can use acoustic clips and resilient channels to decouple the wall and ceiling.
- Absorption – Use materials that are going to absorb sounds. Acoustic insulation is suitable for sound absorption as it converts the sound waves into heat as it passes through the insulation. Dense mass-loaded barriers will also dampen and absorb sound.
