FAQ's
RCM Multipurpose has one smooth face and one textured face, the smooth face should be fixed outermost.
RCM Multipurpose has a rating of A1 to EN13501-1 this is a reaction to fire classification and should not be confused with fire resistance.
Yes, RCM Multipurpose can be left permanently exposed providing all board edges and penetrations are suitably sealed, we would suggest using a sealing coat to maintain long term appearance.
Yes RCM Multipurpose can be used as a tile backer board.
Yes, 12mm thick RCM Multipurpose can be used with RCM Renderflex.
RCM Multipurpose edge distance is 12mm except at the board corners where fixings should be moved up or down to achieve 50mm. Fixings should be fixed using a maximum 600mm x 300mm grid pattern.
- 27 No. fixings per 2400mm x 1200mm sheet when fixed in a vertical orientation.
- 25 No. fixings per 2400mm x 1200mm sheet when fixed in a horizontal orientation.
- For fixing into SFS framing 4.8mm x 38mm self-drilling wingtip fixings suitably treated against corrosion should be used.
- For fixing into Timber framing 4.2mm x 42mm self-drilling fixings suitably treated against corrosion should be used.
