Guidance for specification option:

RockFace A2 SL should be attached with non-combustible fasteners and washers appropriate to the type of substrate being fastened into. Fixing washers should be a minimum 45 mm diameter. Fasteners and washers should be installed so as to prevent RockFace A2 SL panels becoming dislodged by wind or maintenance work. Consult your chosen fixing supplier for recommendations.

When fixing directly to a steel or concrete soffit RockFace A2 SL boards fasteners should be positioned a minimum of 50 mm in from the edges of the board, at 450 mm centres across the width and at 500 mm centres along the length (achieving 8 fasteners per board).

The minimum penetration of the fasteners into the substrate must comply with the fastener manufacturer recommendations. A space of 0.5 to 2 mm should be left between each board to allow for thermal expansion.

Where an uneven surface exists or there are services, and subject to the balconies not being on a building over 18 m in height, timber battens may be used. Minimum 50 x 25 mm treated timber battens should installed 75mm in from all boards edges with additional cross battens positioned to allow the for central zone fixings at 450 mm centres across the width and at 500 mm centres along the 

length (achieving 8 fasteners per board). A space of 0.5 to 2 mm should be left between each board to allow for thermal expansion.

At perimeters the RockFace A2 SL must either abut a vertical surface (a space of 0.5 to 2 mm should be left between each board to allow for thermal expansion) or be closed off with a suitable cover flashing.
