Description

Tecsound SY50ALU Acoustic Membrane 

Product Description – Tecsound SY50ALU

Tecsound SY50-ALU is a polymer-based, bitumen-free, high density synthetic soundproofing membrane, that offers good acoustic insulation coupled with an oil resistant, reinforced, aluminium foil facing. It has extremely high visco-elasticity as well as being extremely flexible even in cold temperatures.

This damping material is unique. Unlike most other foil faced damping sheets which are bitumen based, Tecsound is not only Class 0 fire rated but it tolerates extremes of temperature. It will not harden and crack when it gets cold which would reduce acoustic efficiency. It is also 5kg/m² whereas many other bitumen based products are between 1kg/m² and 2kg/m² and therefore not as effective at damping thicker metalwork over 0.25mm
