Product Application

Tecsound 100 can be used on walls and floors. It can be used to make up high-performance walls and is often used in combination with acoustic mineral wool, acoustic plasterboards and can be used with resilient bars.

On the floor it can be very effectively combined with our SBx Board range and mineral wool to provide an excellent airborne and impact sound barrier to protect from noise from below. We also recommend the use of Tecsound 100 on the floors which has a density of 10kg/m2 for even more robust performance characteristics.

On the ceilings we recommend the use of the self adhesive Tecsound 50SY to make application more straight forward.

Instructions for use

Some of the many uses for the flexible membrane can be seen below. Its use in anything from car sound proofing to improving speaker performance. It also has use in industrial soundproofing.


The performance of tecsound 100 is truly impressive. In fact it performance is equivalent to lead of the same surface weight. The Tecsound 100 in a single layer boasts an Rw figure of over 32db.

Because of its chemical make up Tecsound has exceptional damping qualities. It is these qualities that are normally absent from rigid plasterboard type constructions. This resilience means that it compares very favorably to the likes of green glue as it not only provides great resilience but it also provides good mass.

The membrane has reinforcing scrim on one side, when applying to the floor this should be facing you. When applying to the wall it should also be facing you.

Tecsound Applications

As well as uses in soundproofing walls and soundproofing floors. Tecsound 100 has other applications these include
When added to light weight vibrating and resonating surfaces such as car doors floor pans and bonnets it greatly reduces vibration and the passage of sound through the surfaces. Also it reduces re-radiated sound. Its an ideal product for soundproofing engine bays in boats and other noisy engine rooms.
It can be used very effectively below metal decks and roofs for damping the sound of rain.
In the industrial machinery sector it has been successfully used to reduce sound emanating from machine rooms and noisy equipment
Tecsound 100 is extensively used for creating sound proof booths and hence has been used in the music industry.
