Abstract A roof sheet spacer comprise a body comprising: an elongate strip of material having an upper surface and an underside; and two or more spacer formations extending from the underside of the strip; and two or more sheet fastening clips fixed to the upper surface of the strip, the sheet fastening clips dimensioned and configured to engage ribs of a profiled roof sheet. The strip and the spacer formations may be integrally formed to define a one-piece structure. The body may be of a plastics material or other suitable material such as composites or metal. The strip may include locating formations on the upper surface for locating the sheet fastening clips on the body. The locating formations may stand proud of the upper surface of the strip. The spacer formations may each define a passage which extends from the underside of the strip to distal ends of the spacer formations. The sheet fastening clips may be aligned with the spacer formations along the length of the strip. 5 6 5 8 ,'2 -9 3 >9 4'1 4 Figure 1 (prior art) Figure 2 24.1 |
