The basic structure of the wall module consists of a stable timber frame with cross braces and separate compartments. The individual compartments are lined with a three-dimensional special fabric that sets the shape for the foam filling. The thickness of the wall can be adjusted depending on the insulation required.
Each compartment is then separately filled with components mixed under high pressure, which react together to form rigid polyurethane foam. This makes the wall modules extremely strong, with excellent insulation.
No further layers of insulation are needed. This construction method is applied to wall, roof and floor elements.
