Styro Stone is the registered trade mark for Styrofoam* stones, which when used as a lost shuttering system, provide an extremely economic and environmentally friendly method of wall construction. The resulting wall combines robust construction with very high insulation values. Styro Stone can be used by professionals or self builders, for super fast erection of domestic housing, or industrial buildings. Even exotic swimming pools can be made using Styro Stones. The walls of an average detached bungalow can be erected by 3-4 well trained people in one day.
