FIRE-SAFE ACOUSTIC MINERAL WOOL is particularly useful as a sound absorbing infill for the reduction of airborne noise in partition walls, between flooring joists and suspended ceilings.

The density of this material is generally at least twice that of standard loft insulation so it's much more efficient at absorbing sound. The mass of fibreglass loft insulation is generally only around 20Kg/m³.

AMW consists mainly of silicon-oxide together with a number of other metallic oxides. It is non-flammable and 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.

AMW, when used in a standard studwall, or between floors, can increase the sound insulation performance by 3-5dB.
spray adhesive
Our Spray Adhesive is ideal for sticking these slabs to walls and ceilings.

Supplied in two density grades:
Our 60kg/m³ is the premium acoustic grade version. This offers the best acoustic absorption due to it's specific density.
Our 45kg/m³ is a standard lesser performing lighter version.
If you want to upgrade a ceiling to 1 hour fire resistance without adding any extra plasterboard below then you can use our chicken type wire mesh to hold the mineral wool between the joists to meet this requirement. The combination of the secured mineral wool sitting on the wire mesh, and the existing ceiling, is usually accepted by Building Control as being in compliance with the required fire resistance of a separating floor between flats. Usually the material is friction fitted tight between the joists so you won't need any if working from above. However it is sometimes useful to use it if working from below to prevent the material dropping back down before the plasterboard and bars are fitted.

Rolls are supplied in 1.05m wide x 50m long (52m²). The hexagonal holes are 31mm, so its an extra strong version, and the wire gauge is 19 which is 0.92mm thick wire.
