Acoustic Mineral Wool is sound insulation designed to reduce noise reverberation in cavities.  Very effective when upgrading the soundproofing of walls and floors.



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.

     Product Range    
     AMW 50 50mm thick Acoustic Mineral Wool 1200 x 600mm
     AMW 75 75mm thick Acoustic Mineral Wool 1200 x 600mm
     AMW100 100mm thick Acoustic Mineral Wool 1200 x 600mm
     General Physical Data
     Flammability  BS 476 Part 4 (1970) Non-combustible
     Building Regulations Class O

                           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
