  • NB. Fire integrity performance is for FRstop only. Timloc Building
    Products advise performance criteria is agreed with timber frame
    manufacturer.
  • FRstop must be compressed and friction fit with timber frame and fixed through flange. For vertical applications both flanges are fixed to timber frame. For horizontal applications only the top flange should be fixed. Fix flanges using clout nails at 150mm centres.
