Interlocking Panels consist of a panel face, reveal joint and are fixed in position using hidden fasteners. The panels can be orientated horizontally or vertically and can be applied equally to soffits. Panels are available in all finishes of 1mm thick VMZINC with standard panel widths being 200mm, 250mm and 300mm. The maximum panel width is 333mm and length 6m, panels of less than 0.5m are not recommended. Joint widths can be either 10mm or 20mm. It should be noted that panel width = panel face + joint. The depth of the panel is 25mm.


The system is relatively lightweight as the panels weigh no more than 12 kg/m2 and can be fixed back to both timber and metal sub frames. Support rails are installed at 600mm centres (maximum). Aluminium rails are 2mm thick with both timber and aluminium rails requiring a supporting face of at least 40mm. All panels that are over 2m in length must allow for thermal expansion and contraction by using stainless steel clips. The fixed point being at the top of the panel for vertical installation and in the middle for horizontal installation.
