SYMBI Duplex One Ep. 1: Deck Framing is Done, SIPs Have Begun
SYMBI Duplex One concept home is not like most houses built in America. Instead of 2x6 studs, with OSB sheathing, and fiberglass insulation, the projects is being done with structural insulated panels (SIPs), a high-performance building panel that consist of two sheets of OSB and a layer of rigid expanded polystyrene or extruded polystyrene foam insulation in between.
“SYMBI Homes are built of prefabricated structurally insulated panels, which are factory-built and shipped flat,” Tysvaer says. “SIPs create a tight energy-efficient shell, reduce construction waste, and speed up the building process. SIPs also provide more stability over time, compared to a typical stick-framed home. We don’t see settlement cracks and nail pops in SIPs walls, so less maintenance, too.”
