General Physical Data
Flammability: BS 476 Part 4 (1970) Non-combustible
Building Regulations: Class O
Product Density: 45kg/m3

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 then provide this one-hour fire rating without reducing the soundproofing properties of the product.

Acoustic Performance of AMW typically provides a reduction in reverberant noise levels of up to 10dB when fitted under roof constructions.
