Structural+Insulated+Panels+(SIPs)

Walls made out of styrofoam with steel sheeting on both sides. These wall and roof systems are structural panels and only require sparse framing (for specified spans).

A good example of this system is the Gymnasium at Burgmann Anglican School, Gunghalin (see below). The whole building is made of these panels.
