ACOUSTIC MINERAL WOOL

The density of Acoustic Mineral Wool is more than twice that of normal loft insulation and so is very efficient at absorbing noise.  Acoustic Mineral Wool (AMW) is used extensively in buildings and throughout industry to give acoustic, thermal and fire insulation.  It is particularly useful as a  sound absorbing infill for the reduction of airborne sound between flooring joists, suspended ceilings, stud partitioning and in combination with our Resilient Bars for soundproofing ceilings.

General Description

AMW consists mainly of silicon oxide together with a number of metallic oxides.  It is non-flammable, chemically inert and is not adversely affected by any substance it may come into contact with.  Random arrangement of fibres ensures no water penetration in any direction.  It is rot-proof, non-hygroscopic, does not sustain vermin and will not encourage the growth of fungi, moulds or bacteria.  It will not react with wired plastic or metal wall ties, brickwork or masonry.

In some situations, there is a requirement for party/compartment floors to                               achieve a one hour fire rating.  If AMW100 is supported by 25mm chicken wire                            mesh stapled to joist sides, the insulation will provide this one hour fire rating.
Acoustic Performance		AMW typically provides a reduction in reverberant noise levels of up to 10dB when fitted under roof constructions
