In the aftermath of natural disasters, rebuilding homes is the most urgent need for affected communities. Traditional reconstruction methods often face challenges like long cycles, high costs, and significant energy consumption. Now, an innovative solution—the Duolai Bao EPS Dome House Modular Unit, developed by Henan Yajiate Green Building Technology Co., Ltd.--offers an efficient, economical, and sustainable choice for post-disaster recovery.

The modular construction resembles assembling Lego bricks, yet its thermal performance surpasses traditional brick houses, maintaining comfortable indoor temperatures with minimal energy input.

01 The Core Technology Behind Rapid Reconstruction

The Duolebao EPS Modular House utilizes modified graphene EPS module technology, representing a fundamental shift in construction methodology. This modular light-assembly housing system consists of modified polystyrene modules with advantages unattainable by traditional materials.

Standardized module production ensures dimensional accuracy, while on-site assembly is as intuitive as "building with blocks". This approach dramatically reduces construction timelines while minimizing resource waste and environmental impact.

Compared to traditional materials, these hollow-structured "construction blocks" offer superior insulation and structural performance. The modules are manufactured from flame-retardant polystyrene materials through specialized processes.

02 Exceptional Performance Specifications

The Duolebao system excels in four critical areas that make it particularly suitable for post-disaster scenarios.

Thermal Insulation & Energy Efficiency: The EPS modules feature 11cm thick insulation boards on both sides, with performance exceeding urban building energy standards in many regions. The modified graphene EPS material has a thermal conductivity coefficient of less than 0.022w/m·k.

This enables the structure to maintain indoor temperatures between 18-23°C year-round, reducing energy consumption by 30%-70% compared to conventional buildings.

Wind & Earthquake Resistance: The dome structure follows optimal architectural mechanics principles. This circular design withstands wind loads from multiple directions, offering enhanced stability in high-wind conditions due to aerodynamic advantages.

Furthermore, the reinforced concrete shear wall structure achieves an earthquake resistance rating of up to magnitude 8.

Rapid Deployment: The system demonstrates remarkable efficiency. A 28-square-meter unit requires only 4 workers and 2 hours for main structure assembly. This modular approach contrasts sharply with traditional methods that often require weeks or months.

Cost-Effectiveness: The system offers significant economic advantages. A 28-square-meter module set costs less than 20,000 RMB. Construction costs using EPS cavity modules are now comparable to traditional red brick, while brick construction requires additional insulation that increases expenses.

03 Key Technical Specifications

For international procurement and technical evaluation, here are the essential specifications of the Duolebao system:

04 From Emergency Shelter to Semi-Permanent Housing

The Duolebao EPS Modular House serves not only as immediate post-disaster shelter but also as semi-permanent housing. These durable modular structures can accommodate transitional needs from emergency*** to longer-term***.

Henan Yazhante Green Building Technology Co., Ltd. has enhanced the system with innovative designs. Their patented base wall template for low-rise assembled buildings enables rapid module connection through ingenious locking blocks and slots.

The base body includes installation cavities for landscape equipment panels that can support greenery or lighting features, improving aesthetic appeal and adding vitality to post-disaster environments.

The complete Duolebao structure comprises multiple double-curve modules, with exterior surfaces that can receive mortar coatings and painted designs, creating psychologically comforting environments for displaced families.

05 Environmental Sustainability

The Duolebao system embodies green building principles through both materials and construction methods. The EPS modules utilize recyclable flame-retardant polystyrene materials manufactured through specialized processes.

Modular construction dramatically reduces construction waste. Compared to traditional methods, there's virtually no leftover building material, minimizing both waste and cleanup requirements.

Additionally, EPS module buildings significantly reduce energy consumption during use. Their exceptional insulation properties decrease heating and cooling demands, substantially lowering carbon emissions over the long term.

The system supports global sustainability goals while addressing urgent humanitarian needs in post-disaster scenarios.

In a quiet night, warm light glows from a white dome-shaped cottage where a family of three gathers together. The wind howls outside but barely penetrates the 11cm thick EPS insulation barrier.

This shelter, assembled in just two hours, will protect them through seasons and storms until permanent reconstruction is complete.
