Structural Insulated Panel's
-What is structural insulated panel construction? They are a composite building material. They consist of an insulating layer of rigid core sandwiched between two layers of structural board. The board can be sheet metal, plywood, cement, magnesium oxide board (MgO) or oriented strand board (OSB) and the core either expanded polystyrene foam (EPS), extruded polystyrene foam (XPS), polyisocyanurate foam, polyurethane foam or composite honeycomb (HSC). It has been proven that Structural Insulated walls are useful everywhere.
-In order for you to use this type of construction you will need a building permit.
