“Dubbed the “habitat for the 21st century,” the Dome House is an igloo-shaped structure built from snap-together wall sections made of 100% expanded polystyrene foam (styrofoam). It might seem like an odd choice of material for a house, but the company lists a number of advantages that styrofoam has over traditional materials. Unlike wood and metal structures, for example, the styrofoam Dome House does not rust, rot or attract termites. It is also highly resistant to earthquakes and typhoons. In addition, the walls, which are treated with a flame retardant, emit no toxic fumes in a fire.
The styrofoam used in the Dome House’s 175-millimeter (7 in) thick walls is significantly denser and stronger than ordinary packing foam. The material has excellent thermal insulation properties, resulting in higher energy efficiency and lower heating and cooling costs.ricated pieces, which each weigh about 80 kilograms (175 lbs), can be carried by 2 or 3 people and assembled in a few hours. Once the shell is put together, coats of mortar and paint are applied for further protection from the elements.
By kneading “antioxidant solution” into expanded polystyrene, or the building material for the Dome House,active oxygen can be suppressed, resulting in the prevention of aging and the recuperation of your health. Also,because the Dome House is a formaldehyde-free building, you don’t need to worry about sick-house syndrome.
Because the Dome House uses expanded polystyrene as the building material, excellent thermal insulation can be obtained. Also, owing to its dome-shape, the Dome House allows the air to circulate by convection without being accumulated at the corners.
The Dome House is not only stable in structure but also extremely light in weight. It is because of this lightweight that the Dome House can withstand earthquakes.”
