FAQ's
RCM Renderflex has one smooth face and one textured face, the smooth face should be fixed outermost.
RCM Renderflex has a rating of A2 to EN13501-1 this is a reaction to fire classification and should not be confused with fire resistance.
No, RCM Renderflex cannot be left permanently exposed.
RCM Renderflex 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.
RCM can supply Poly Crystalline Diamond (PCD) blades suitable for cutting RCM Renderflex in a range of diameter and bore sizes, please contact RCM Technical department for further information.
