For effective reduction of airborne noise through floors!
The density of Sonofleece™ Soundproofing Acoustic Mineral Wool is more than twice that of normal loft insulation and so is very efficient at absorbing noise. Acoustic Mineral Wool (Sonofleece™) 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 noise between flooring joists, suspended ceilings, studwall partitioning and with our Acoustibar™ Resilient Bars.
Soundproofing Sonofleece™ consists mainly of silicon oxide together with a number of other 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.

Flammability BS476 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 Sonofleece™100 is supported by 25mm chicken wire mesh stapled to joist sides, the insulation will provide a one hour fire rating. Acoustic Performance Sonofleece™ soundproofing acoustic mineral wool typically provides a reduction in reverberant noise levels of up to 10dB when fitted under roof constructions Sound Absorption coefficients The graph below shows typical sound reduction obtainable under test conditions Slab Size: approx. 1200mm x 600mm Thickesses:approx. 50mm, 75mm and 100mm Weight: 50mm: 3.25Kg/m² 75mm: 4.75Kg/m² 100mm: 6.25Kg/m² Density: 60Kg/m³ Thermal Conductivity: 0.033W/mK
