Moulded and interlocking insulation board

THERMOFOAM® insulation boards differ from conventional insulation products, for their superior physical properties due to their manufacturing process, which in fact results from moulding along with their unique airtight joint interlocking design. The interlocking system enables a quicker and hermetic installation of the boards.
