Acoustica^® NoiseShield^®

Acoustica^® NoiseShield^® is a rigid laminate noise barrier and vibration damping material which has been specifically engineered for machinery enclosures, machinery rooms and other vibrating machinery.

NoiseShield^® has a unique material construction which unlike many other insulation materials results in high sound absorption coupled with resilience and compression loading capability.

NoiseShield^® effectively treats the often combined phenomena of vibrations, sound transmission and sound reverberation encountered with most noise problems

NoiseShield^® is an extremely robust aluminium faced insulation with an indefinite life that is unaffected by oil, water, hydrolysis and vibration; it does not shed fibres nor will it delaminate.

Environmentally friendly and safe and clean to handle, NoiseShield^® is fire rated according to AS1530.3.

Ignitability Index (0-20) = 0
Spread of Flame (0-10) = 0
Heat Evolved Index (0-10) = 0
Smoke Developed Index (0-10) = 0-1

With it’s indefinite life, NoiseShield^® is an economical material that effectively reduces sound radiation & sound transmission in the critical frequency region of rigid panels such as, steel, fibreglass, aluminium, etc)
