Product Description - Tecsound 35, 50, SY50, SY70, 100 and SY50-ALU
Tecsound membranes are polymer-based, asphalt-free, high density, synthetic soundproofing membranes, that offer good acoustic insulation in different building elements. The membranes have extremely high visco-elasticity as well as being extremely flexible even in cold temperatures.
This material has excellent sound insulating properties. Many construction materials and techniques do not provide enough damping. Rigid sheet materials such as plasterboard absorb little sound energy because they tend to vibrate and re-radiate sound on the other side quite effectively. However, Tecsound acoustic membrane has tremendous density and mass while remaining extremely flexible. It is acoustically better than lead of the same surface mass, so will help absorb sound energy far more efficiently.
While some systems rely on visco-elastic glues to provide damping the results achieved will vary greatly depending on the application of the glue. Is it too thick? Is it too thin? Has it been applied evenly and consistently?
Visco-elastic glues do not add any extra mass to a system and at the end of the day the best way to reduce bass transmission is by having a heavyweight, heavily damped, mass/spring system. Tecsound acoustic membranes provide the best of both worlds: high additional mass and high damping that can be applied uniformly over 100% of the area to be treated.
