ApplicationParty separating walls
MaterialGlass Mineral Wool
Masonry Party Wall Slab is a Glass Mineral Wool slab, designed for use in masonry separating party walls, that offers thermal and acoustic performance.
It is non-combustible insulation with the best possible Euroclass A1 reaction to fire classification, and is manufactured using Knauf Insulation's unique bio-based binder, ECOSE® Technology.
- Fully filling the party wall cavity contributes towards a zero effective U-value, simplifying compliance with building regulations.
- Suitable for use with a range of constructions registered in the Robust Details Handbook reducing the need for on-site acoustic testing.
