Upgrade your noise control with Tecsound SY, a premium soundproof membrane engineered to deliver outstanding airborne noise reduction through walls, ceilings, and even floors.
This self-adhesive soundproof membrane is ideal for residential and commercial settings, including homes, flats, studios, and offices – especially where space is limited and noise control is a priority.
Tecsound SY acts as an ultra-thin yet powerful soundproof membrane for walls and ceilings, and can also be layered as a soundproof membrane for floors to boost acoustic insulation. Easy to install – just peel and stick – it offers maximum performance with minimal disruption.
Tecsound Soundproof Membrane – High-Performance Acoustic Barrier for Walls, Ceilings & Floors
Looking for a powerful way to block unwanted noise? Tecsound Soundproof Membrane is a high-performance acoustic barrier designed to reduce airborne sound transmission through walls, ceilings, and floors. Tecsound delivers superior results without adding bulk to your structure.
Key Features:
Exceptional Soundproofing – Tecsound is a dense, viscoelastic soundproof membrane that drastically cuts down airborne and impact noise, especially in mid-to-high frequencies.
Slim & Flexible – Just a few millimetres thick, it offers high sound insulation with minimal added thickness—ideal for tight spaces.
Versatile Use – Suitable as a soundproof membrane for walls, floors, and ceilings. Perfect for stud walls, party walls, and floor underlays.
Self-Adhesive Option – Tecsound SY comes with an easy peel-and-stick backing, reducing installation time and mess.
Vibration Control – Effectively absorbs vibrations, helping to reduce both structural and airborne noise.
Why Choose Tecsound?
Tecsound is the go-to soundproof membrane for floors and walls where acoustic performance and space-saving design are essential. Whether you’re combating noisy neighbours, echo in office spaces, or footsteps above, Tecsound offers a proven solution. For enhanced results, combine it with acoustic plasterboard, mineral wool, or soundproof panels.
Popular Applications:
- Soundproofing party walls in terraced or semi-detached homes
- Increasing floor sound insulation between flats or office levels
- Reducing ceiling noise from footsteps or voices overhead
- Enhancing acoustics in studios, home cinemas, and workspaces
Available in multiple weights and thicknesses, including TecsoundSY50, SY 70, and SY 100.

Tecsound 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. It is used predominantly between sheets of acoustic plasterboard in soundproof systems for walls and ceilings.
The self-adhesive Tecsound sheets are suitable for most wall and ceiling surfaces. One of the primary applications of Tecsound is between sheets of plasterboard. The product’s viscoelastic nature and high mass/density ensure that vibration and airborne sounds are significantly reduced when applied to the plasterboard. Use Tecsound directly on the metalwork to minimise structural vibration.
• 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 performance
• 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
- 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.
