And a couple of days after the walls went up we also had a roof. We arrived on site at 2 pm to witness the progress of installing the Thermospan metal SIP roof panels but all 13 eight meter long panels had already been installed. Not bad to install a complete roof in 4 hours. The panels are structural so no supporting beams necessary and they can span the full width of our home of 6.2 meters. The exterior steel sheet is the exterior cladding so no building wrap, battens and additional roofing cladding necessary and an insulation value of R5.3.
