SQUAREACOUSTIC™ Sandwich Panel
Acoustic panels are developed for internal walls and ceilings in industrial applications, where special sound insulation or sound absorption is needed. In industrial facilities especially the noise level from machinery can rise so high that it effects working convenience and can even cause hearing damage if precautions are not taken. The most reasonable way to solve the problem is to separate people from the machinery by building sound insulated machine rooms or acoustic screens.
Acoustic panels have perforated surface on one side providing better sound absorption.
Core Thickness: 50, 100mm
(Other thicknesses are available upon request)
Maximum panel size: (W) 1,125 x (L) 6,000 mm.
Acoustic panel works in two distinct ways to reduce noise, by impeding the transmission of sound through an element of structure and by absorption of sound at the surface. The noise absorption co-efficient is expressed as a factor. The more sound that material can absorb, the higher noise absorption co-efficient will be.
