Boutique Modern Structurally Insulated Panel System

The modular units comprise walls of 2 skins of OSB/3 separated by a core of polyurethane insultation. The panel thickness is 150mm and can be manufactured to the maximum dimensions of 2.0m in height and 6.25m in length. A ring beam forms the perimeter of the floor base panel. The beam is bolted to a galvanised steel angle which in turn is bolted to the foundation.
