INSTALLATION METHOD It is strongly recommended that sheets are laid with the side laps facing away from the direction of the prevailing wind. Where possible, the roof sheets should be fixed with the side laps facing away from the normal line of sight. SIDE LAP AND FLASING Side lap fasteners are required at mid spans for purlin spacings over 1,000mm and for girt spacings over 1,200mm. For all side lap and flashing fastening, use no. 10 x 25mm self drilling Hexagon Head Screw with pre-assembled neoprene bonded steel washer. END LAPS AP RIB is available in continuous length limited only by the maximum transportable length of 20m. For longer length, end lap is necessary. Minimum end lap should be 200mm and for roof pitches below 8º, the lap should be treated with a recommended sealant.
