Sonofleece™ SOUNDPROOFING ACOUSTIC MINERAL WOOL

Sonofleece™ soundproofing material

For effective reduction of airborne noise through floors!

Introduction

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.

General Soundproofing Description

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.

General Physical Data

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
