• The core structure of an Xtend building is made from SIPs panels - high-performance material for building construction. The 21st-century way to build
• 9 7mm thick insulated walls consist of 75mm of polystyrene insulation sandwiched by two sheets of oriented strand board (OSB)
• Gives structure and insulation in one pre-assembled and cut-to-size panel
• Total wall thickness including SIPS panels, internal and external cladding and cavities is 177mm
• Roof is 11mm OSB + 100mm insulation + 11mm OSB = 122mm total
