Product Summary

Tecsound 70 is a very high performance acoustic membrane. Its main use is in the soundproofing of floors. The extra mass of the Tecsound 70 versus the Tecsound 50 makes it the prefered product when sound proofing a floor. It is flexible and improves both impact and airborne passage of sound. It is a high density polymer based synthetic soundproofing membrane providing excellent acoustic insulation in different construction elements. The product is fire resistant and self extinguishing.

Product Application

Tecsound 70 can be used on walls and floors, on ceilings we recommend Tecsound50 self adhesive. 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 doubling up of Tecsound 70 on the floors to create a density of 14kg/m2 for even more robust performance characteristics.

On the ceilings we recommend the use of the self adhesive tecsound 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 70 is truly impressive. In fact it performance is equivalent to lead of the same surface weight. The Tecsound 70 in a single layer boasts an Rw figure of over 28db.

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 high 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 70 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 70 is extensively used for creating sound proof booths and hence has been used in the music industry.
