Structural Panels Australia is an Australian owned company, based in Bayswater, Victoria that manufacturers Structural Insulated Panels (SIPS). SIPS can be used for all wall & floor applications. The SIPS panel is made up of an insulation core with skins on either side of it. Generally, the insulation core is of EPS (Expanded Polystyrene) and the skins are of OSB (Orientated Strand Board). SIPS are a load bearing structural system which replaces conventional timber stud framing & insulation in a single panel.
