Systematic exposition
The integrated interior and exterior enclosure wall incorporates thermal bridge-free technology that eliminates both linear and point thermal bridges. It’s composed of multiple layers—including the main structural framework, thermal insulation, waterproofing, vapor barrier, and exterior finish—each layer meticulously selected to ensure optimal performance. The exterior finish can be customized with a variety of materials to meet specific design requirements. The roof also features a modular, monolithic construction design, offering the dual benefits of fully prefabricated assembly and high energy efficiency. High-performance windows with a U-value of 0.8 W/(㎡·K) are used, while the exterior walls and roof have a U-value of 1.0 W/(㎡·K). Paired with a five-parameter intelligent fresh-air system, these features guarantee indoor comfort. Heating systems can be chosen according to the owner’s specific needs.
Core advantages
1. All-domain climate-friendly buildings: Adaptable to various environmental conditions, achieving energy efficiency and comfortable living experiences under all climate conditions.
2. Outstanding spatial efficiency: Integrates multiple functions—including thermal insulation, decoration, and structural protection—eliminating the need for additional functional layers. This reduces wall thickness by approximately 30%, thereby increasing the usable floor area of the building.
3. Rich decorative options: The facade decoration can fully meet the architectural design requirements, is compatible with various dry-hanging and coating-based decorative materials, and supports the installation of photovoltaic systems.
4. Significantly shortened construction period: Modular design and factory prefabrication, combined with digital production accuracy up to ±0.5mm, enable easy installation and reduce the construction period by approximately 40%.
5. Structural Safety and Ultra-Long Durability: The module’s main body and core load-bearing components are made of high-quality steel, backed by a 50-year manufacturer’s warranty, ensuring safety and reliability throughout the entire lifecycle.
6. Excellent overall cost-effectiveness: The integrated system features a streamlined, in-depth design that reduces the complexity of coordination among different disciplines, minimizes on-site auxiliary labor and materials, and enables precise control over overall project costs.
7. Industry-leading energy efficiency: Featuring a uniquely designed low-thermal-bridge structure, combined with high-performance windows, doors, and curtain walls, our products exceed current stringent standards such as passive house and zero-energy building requirements.
8. Higher Floor Area Ratio: Compared to conventional energy-efficient buildings in cold regions, under the same external footprint, the usable floor area increases by approximately 6-7%, and the building’s prefabrication rate can reach up to 79%.
