Tecsound SY70 is a high density visco-elastic polymer-based, asphalt-free, synthetic soundproofing membrane, that offers good acoustic insulation in different building elements. It is equipped with a self-adhesive layer, to allow its direct application on the majority of building surfaces.
Tecsound Sy70 soundproofing membrane has outstanding sound insulating properties. Most construction products do not provide damping. Plasterboard and plywood materials absorb little sound energy because of their rigidity. Tecsound acoustic membrane with it’s mass, density and visco-elastic properties provides superior acoustic performance to basic gypsum plasterboard wall and ceiling constructions. It is also available in a 10kg per m² version.
Tecsound SY Acoustic Membrane provides the best of both worlds, high additional mass and high damping.
