Fire-Safe acoustic mineral wool
This acoustic mineral wool (AMW) is particularly useful as a sound absorbing infill for the reduction of airborne noise in partition walls, between flooring joists and suspended ceilings. AMW consists mainly of silicon-oxide together with a number of other metallic oxides.
It is FAR MORE efficient for soundproofing purposes than lightweight thermal fibreglass loft insulation which should not be used in place of high density acoustic grade mineral wool. It is non-flammable and chemically inert and is not adversely affected by any substance it may normally 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.
PLEASE NOTE: When fitting mineral wool slabs between joists or between frameworks you won't need as much material as the total overall area because of:
a) the thickness of the joist or frame
b) the width of the joist or frame.
c) the spacings between.
The larger the area to be treated the fewer packs you will need: for a small area there will be little difference, but when you get to 100m² plus it will pay to make accurate calculations. As a generalisation, assuming the width of a frame to be 50mm at 600mm spacings, you would have approx. 8% in excess.
The Prorox and RW are interchangeable, the packaging is the only difference. To avoid confusion we have used both codes when referring to these materials because sometimes we have one or the other depending on what Rockwool supply.
