ProTherm RockFace A2 is a Non-combustible Upstand Insulation Board used to thermally insulate and protect upstands and external walls in inverted flat roofs, warm roofs and balconies.
Manufactured from class A1 Non-combustible Stonewool factory laminated to a 6mm thick weather resistant high impact calcium silicate fibre cement facing board, ProTherm RockFace A2 will not develop smoke or promote flame spread, even when directly exposed to fire. ProTherm RockFace A2 repels and drains away water, completely drying out while maintaining its original physical properties. The calcium silicate fibre cement facing board is BBA certificated (BBA certificate No. 21/5983) and independently tested and classified as Category A for external use in accordance with EN 12467:2012. Available in a range of thicknesses, see declared performance table for available thickness.
ProTherm RockFace A2 is not intended to provide a final architectural/aesthetic finish as the cementitious facing may vary in colour from batch to batch. To achieve a consistent aesthetic finish the facing board can be primed and decorated with an appropriate masonry paint or render finish.
ProTherm RockFace A2 has a Zero Ozone Depletion Potential (ODP), a Global Warming Potential (GWP).
