Fixing: Wall ties are used, as standard, vertically every 450mm mortar course. Helical ties are most useful where additional support is required between courses and can be fixed through the flat face of the sheet.
For timber frame, it is recommended that sealing washers (supplied by SureCav) are screwed into the pods, with or without additional timber frame ties to hold the system in place prior to the construction of the outer masonry leaf.
Use 5 washers per sheet to ensure stability in high winds before the outer leaf is constructed.
