Product Application

Tecsound 50 can be used on walls floors and even ceilings. It comes in a self adhesive and non adhesive form. 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 50 on the floors to create a density of 10kg/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

The Tecsound acoustic membrane can be applied to most surfaces including rendering , plasterboard, metal, and most plastics. The surface should be even smooth clean and dry. The surface should be cleared of any elements that might cause damage to the membrane. Old plaster work should be checked and possibly primed first to ensure good adhesion.

When adding to a wall you have a number of choices. With a resilient bar system we recommend that you add it at the 19mm plasterboard planc level. You have two choices the first is to glue regular Tecsound 50 with a high performance adhesive like Stayput. The second is to use the self adhesive Tecsound 50 membrane. The membrane should be overlapped at junctions and run right up to the walls and ceiling overlapping by around 10mm.

When adding to the floor we ideally recommend adding straight to the floor surface. This can be onto floor boards or to other floor surfaces. However you can also add draped over the joists, if you are looking to have wooden floor boards above. Again at the joins we recommend at least 3cm overlap and run the membrane right up to skirting boards or walls so no gap is left.

Ceiling applications can prove trickier and we would tend to use our other membrane which if lighter and easier to handle. However if you are set on using Tecsound 50 on the ceiling we would again apply it after the the 19mm board. The self adhesive variety is the easier to use and this can then be sandwiched between the 19mm and 12.5mm boards.

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.

Performance

The performance of tecsound 50 is truly impressive. In fact it performance is equivalent to lead of the same surface weight. The Tecsound 50 in a single layer boasts an Rw figure of over 25db.

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 50 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 50 is extensively used for creating sound proof booths and hence has been used in the music industry.
