Standard walls are a composite construction of two skins of High Pressure Laminated over aluminium framework with a sealed and insulated interior. Standard panel chargable heights are 1220 mm wide with an overall length of 2500, 2800, 3100 mm. Standard panels have an overall thickness of 50mm. the semi monocoque construction is self supporting. the self supporting, insulated walls are constructed with an interior aluminium framework. A 70 mm floor track is used to level and support the wall system. Panel to panel connections are maintained with precision by aluminium profiles that create uniform (4 mm) seams. The panel seams are selaed by silicone with a perfectly flush finishing. Insulation materials are sandwiched between the two skin layers and sealed from the exterior by the aluminium framework. The standard insulation material for the wall system is polyurethene.
