Superior Features of Dome House

The Dome House is made out of functional, durable resin.
It is the first dome-shaped structure constructed of expanded polystyrene to be certified
by the Minister of Land, Infrastructure, Transport and Tourism.
The use of this special material provides it with features that set it distinctly apart from other buildings.

Superior Thermal Insulation

Expanded polystyrene contains a large amount of air, giving it superior thermal insulation properties.The Dome House is made from special expanded polystyrene that is 17.5 cm thick, so it keeps outside heat from getting in and does not let cool or warm indoor air escape.

Energy Saving Building

The high thermal insulation properties protect it from the impact of outside temperatures, so it has the energy-saving effect of allowing indoor temperature control with less energy. Moreover, the dome shape makes heat loss very small, further increasing the energy-saving effect.

Superior Durability

Domes are the most structurally stable shape. On top of that, without the impact of UV rays, chemicals, heat, etc., expanded polystyrene does not rust or corrode, so it is a semi-permanent material.

Surface Treatment

The expanded polystyrene is 17.5 cm thick, giving it sufficient strength.Additionally, it is surface treated with UV protection coatings and other treatments to prevent degradation, further improving its durability.

Super Lightweight Material

The Dome House is made by assembling pieces of expanded polystyrene.The weight of the amount of expanded polystyrene used in a single structure is only around 850 kg. Because it is lightweight, it is advantageous for transport, construction and earthquake resistance.

Earthquake Resistant

The Dome House is extremely lightweight and has a low center of gravity, so it is much less likely to collapse than regular buildings. Additionally, the simple structure has no columns, so the roof will not cave in. Even in heavy tremors, the space inside remains safe.

Resistance to Snow Accumulation

One of the characteristics of expanded polystyrene is its high resistance to compressive force. On top of that, the solid dome structure and round shape give it excellent adaptability when it comes to snow accumulation.

Resistance to Strong Winds

The streamlined shape of the dome protects it from direct wind. Moreover, the legs of the pieces are buried securely in the foundation, so it can withstand even very violent typhoons.

Extremely Fast Construction

The Dome House is constructed by assembling the pieces. Each piece weighs only 70 kg, so the work is easy and can be accomplished in about seven days by three or four people. (Construction time will vary depending on location and weather.)

Low Cost

The Dome House is made of prefabricated pieces, so it is a simple structure with a small number of parts. The parts are lightweight and easy to transport, so it can easily be assembled even in narrow spaces. Construction can be completed in a very short period of time by a small number of people.

Environmental Measures

The Dome House is made of expanded polystyrene. This material is comprised solely of carbon and hydrogen and is formed in a very clean, energy-saving process. The house is friendly to both those who live in it and the global environment.

Tranquil Space

The interior of the Dome House is more spacious than you would imagine from the compact exterior, and the cornerless space provides a sense of tranquility. It’s also a safe space protected from various aspects of the external environment.
