Features of Dome House
Features
1
Excellent thermal insulation
Special expanded polystyrene with a thickness of 20 cm. Expanded polystyrene is an excellent insulator due to its air content. Dome houses made of 20 cm thick expanded polystyrene effectively block external heat and retain indoor temperatures.
2
Energy-saving Building
A dome shape that minimizes heat loss. Its high insulation and resistance to external factors allow energy savings by requiring minimal energy to regulate indoor temperatures. Additionally, the dome shape minimizes heat loss, enhancing its energy-saving effect.
3
Excellent Durability
The dome shape is the most structurally stable form. The expanded polystyrene dome does not rot, rust, or corrode. The dome shape is the most structurally stable form. Furthermore, expanded polystyrene does not rust or rot and is highly resistant to changes caused by UV rays, chemicals, or heat, offering semi-permanent stability.
4
Surface Treatment
Multiple surface treatments, including UV-cut coatings, are applied to the 20 cm thick expanded polystyrene, enhancing its strength and durability.
5
Ultra-lightweight Material
An ultra-lightweight structure, approximately 970 kg per unit. Dome houses are assembled using pieces made of expanded polystyrene. The total weight of expanded polystyrene for one house is only about 970 kg.
6
Peaceful Space
A wide and open interior space. The interior of a dome house is far more spacious and open than its compact exterior might suggest. The lack of corners in the space creates a feeling of tranquility, and it is also a safe space, well-protected from any external environmental factors.
7
Environmental Measures
Dome houses are made from expanded polystyrene. Expanded polystyrene is made only of carbon and hydrogen, and its molding process is extremely clean and energy-efficient.
Resistance: Disaster performance
1
Earthquake Resistant
Being extremely lightweight and having a low center of gravity, it poses a much lower risk of collapse compared to typical structures. Additionally, due to its simple structure with no columns, the roof won’t collapse, ensuring safety even in strong tremors.
2
Snow Load Resistant
Expanded polystyrene is highly resistant to compressive forces, a notable characteristic of the material. In addition to this characteristic, the dome shape’s strong structure and round form provide excellent snow load resistance.
3
Wind Resistant
The streamlined shape of the dome makes it less susceptible to wind pressure. Furthermore, the legs of the pieces are embedded and fixed to the foundation, allowing it to withstand very strong typhoons.
Good Workability
1
Ultra-short Construction Period
Dome house construction involves assembling pieces. Each piece weighs only about 80 kg. The process is simple, and with 3 to 4 people, it can be completed in about 7 days. (After the foundation work is completed, the time may vary depending on the location and weather conditions.)
2
Low Cost
Fewer Components and Simple, The dome house uses a piece-assembly system, so it requires fewer components and is simple. The parts are lightweight and easy to transport, making assembly easy even in tight spaces. It can be built by a small team in a very short time.
Development and Performance of Dome House
Our ‘Special Expanded Polystyrene Dome House’ has met strict standards for all conditions, including earthquakes, wind, and snow, and has been certified by the Minister of Land, Infrastructure, Transport and Tourism as the fourth structural material, following wood, steel, and concrete. Its high performance has also been demonstrated in experiments conducted by various research institutions.
