19.0 ROOF PANEL INSTALLATION SEQUENCE
19.1 HR3 roof panels must be installed in a specific sequence. This ensures the correct lapping of the side and end laps (see figure 12, below).
The panel numbers correspond with the order of installation.
19.2 As each panel is installed, all main fastening and lap fastening should carried out. This is especially important on HR3 roof panels and will
ensure that unnecessary back trafficking over the roof is avoided (refer to section 17.9).
20.0 INSTALLATION PROCEDURE
20.1 As each individual panel is removed from the bundle, the male and female edges should be visually examined and any over-spill of
insulation should be carefully removed.
20.2 The first HR3 panel to be installed can have the overlapping hi rib edge cut back or not.
20.3 The roof panel should be laid flush with the face of the wall panel as shown on the shop drawings. It is important that the first tier of panels
are laid true to line, properly lined with a string to ensure a true and neat run.
