Manufacturer guidance

CFS Concrete fixings screws are available to accommodate a combined backing board and insulation thickness of up to 267 mm. A 6mm pilot hole is required. A Tecties stainless steel compression sleeve the same depth as the insulation is required with semi rigid insulation. See tables for screw references, technical specifications and fixing centres.

CFS Concrete fixings screws are also available for fixing the channel directly back to concrete where no insulation is present, for further information please contact manufacturer.

Note: concrete strength increases with age and care should be taken when fixing CFS Concrete fixings screws into older concrete. For further information and technical queries please contact the office.
