Foil Faced 2 Sides Fire Slab Rockwool RWA45 25mm is an aluminium foil faced both sides fire and acoustic stone wool core insulation slab developed to prevent the spread of flames and inhibit heat and smoke through concealed spaces in buildings.

Rockwool RWA45 Foil Faced Two Sides Fire Barrier Slab 25mm x 600mm x 1200mm fire performance integrity is 240 minutes, and 60 minutes for the insulation core with a certified lambda (thermal conductivity) of 0.035W/mK.

25mm Foil Faced Both Sides Rockwool RWA45 Fire Barrier Slab is a standard density (45kg/m3) non-combustible foil backed slab with a great fire performance classified as Euroclass A1, suitable for both new build and refurbishment projects.

Fire Barrier Slab offers excellent thermal, acoustic and fire insulation properties, is water repellent, durable, cost effective, easy to handle and install solution.

Double Sided Rockwool Slab is a simple butt joint product that can be used where fire resistant walls need to be continued above a ceiling into the roof void.

They conform with the Building Regulations Approved Document B and fulfil all normal fire insulation requirements for division of space.

Special sizes and thicknesses are available, made to order: black or white tissue and aluminium foil facings on one or both sides are available in 600mm x 1200mm insulation slabs.

Rockwool insulation does not contain gases that have ozone depletion potential (ODP) or global warming potential (GWP).
