Stratclad™ Installation Information
Stratclad Fixing and Laying Directions - Non-Cyclonic Areas
Note: The following recommendations apply to non-cyclonic areas.
- All fasteners must have neoprene washers to prevent water penetration.
- Side lap fixing is recommended at no greater than 300mm centres for external applications. For internal applications where support spacings exceed 1000mm it is recommended side laps are fastened mid-span. Use either 8x12 mm self drill stitching screws (with seal) or 3.2 mm sealed blind rivets.
- The below fastener sizes are suitable for fixing over an insulation blanket up to 55mm thick. For thicknesses up to 100mm, the next standard screw length to that indicated is to be used.
