Manufactured with non-combustible Stonewool it will not develop smoke or promote flame spread, even when directly exposed to fire. It also repels and drains water away from the product, and will completely dry out while maintaining its original physical properties. Stonewool is factory laminated to a 6mm thick weather resistant high impact facing board. Available in a range of thicknesses, see declared performance table for available thickness.
ProTherm RockFace A2 has a Zero Ozone Depletion Potential (ODP), a Global Warming Potential (GWP) of less than 5.
For use with Inverted roofing waterproofing such as PermaQuik PQ6100, EshaFlex, EshaUniversal and ParaFlex.
ProTherm RockFace A2 is a non-combustible insulated upstand board for use on inverted flat roofs and balconies. 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 Cement Particle Board (CP Board) facing can be primed and decorated with an appropriate masonry paint or render finish.

Install ProTherm RockFace A2 upstand board after completion of the PermaQuik PQ6100 or EshaFlex inverted roofing system.
ProTherm RockFace A2 upstand board is bonded to the waterproofing using an INSTA-STIK bead it is also trapped at the base by the horizontal ProTherm insulation board. As long as the ProTherm RockFace A2 upstand boards are well protected no additional attachment method is required unless the ProTherm RockFace A2 upstand board is more than 3 times the height of the horizontal ProTherm insulation board.
Where the ProTherm RockFace A2 is more than 3 times the height of the horizontal ProTherm insulation board, and less than 750mm in height, the ProTherm RockFace A2 upstand board must be trapped at the base by the horizontal ProTherm insulation board and have continuous retention across the top face of the board.
Where the ProTherm RockFace A2 Board exceeds 750mm above the roof finishes and is trapped at the base by the horizontal ProTherm insulation board the ProTherm RockFace A2 Board must be either:
• Bonded with INSTA-STIK Roofing Adhesive applied in 19-25 mm beads at 300mm centres for the full height of the ProTherm RockFace A2 Board AND have a single DDS fixings (or equal approved) installed through the centre of the ProTherm RockFace A2 Board a minimum of 75mm from the top of the ProTherm RockFace A2 Board.
• Mechanically fixed directly to the upstand wall at 600mm centres using Speedline DDS fixings (or equal approved).
• Where it is necessary to cut ProTherm RockFace A2 upstand board to size use a TCT saw (suitable PPE must be used including a face mask to guard against dust).
