Construction Composite Sandwich Wall Boards Material

Structural insulated panel, also called MGO SIP and MGO sandwich board. It consists of a sandwich of two layers of structural board with an insulation foam in between. Panel skins are magnesium oxide boards. Insulation core can be expanded polystyrene(EPS) and extruded polystyrene(XPS) and so on. These are structural sheaths that can be finished like drywall on the interior, and covered with siding materials or have stucco applied directly to the exterior of the panel. When the panel is used for basement or foundation walls, foundation spray can be applied directly to the surface.


Advantages

Fast construction, with less reliance on highly skilled trades.

Eliminates framing, insulating, vapour barrier installation and wall cribbing.

Energy efficient - up to 40% heat loss reduction vs stick built. Significant heating and cooling savings. Less temperature fluctuation, less drafty, provides an excellent sound barrier creating a more comfortable living environment.

Superior structural strength to stick built. Performs better under extreme weather conditions - earthquakes, hurricanes, etc. Less material waste and handling. Superior wall strength. No nail pops. Cabinetry and pictures easier to hang.

Interior and exterior walls can be finished without additional sheathing - eliminates costly steps and additional materials. Available with wood and grain outside wall finish.

Applications:

The flexibility of our building system is ideal for many applications including residential, industrial shops and warehouses, ready to move buildings and trailers, hotels, factories, aircraft hangars and apartments.
