The ISB® Building System stands as a testament to years of meticulous research and development aimed at meeting emerging market demands while prioritizing simplicity, speed, and efficiency in execution. Through a rigorous development process, we have focused on refining construction technologies and kits to their simplest forms.
The ISB® Building System represents a revolutionary approach to construction, offering a modular, lightweight structure built with a silicate-based manufacturing technology. At its core, it embodies a permanent formwork system, with wall and formwork elements crafted into 20×20 cm modules. These elements are constructed from mineral wool, model gypsum, silicate-based aerated concrete, and extruded polystyrene. Within the ISB system, these elements are integrated into a prefabricated welded steel reinforcement cage, precisely positioned to ensure minimal concrete coverage as per design specifications. The concrete pouring is executed based on concrete technology plans or instructions.
One of the system’s key advantages lies in its ability to provide greater structural strength with a 20 cm thick wall compared to a traditional 30 cm thick brick wall, resulting in a potential increase of 5-8% in net floor area of buildings. Additionally, the technology facilitates significant cost reductions, such as a decrease in the rental period of formwork.
Projects utilizing the ISB® Building System benefit from the collaboration of structural and architectural designers. To ensure the protection of structures built using ISB elements, it is essential to provide waterproofing against operational and utility water for residential, accommodation, and public buildings with water technology functions (e.g., bathrooms, showers, laundries). Supplementary components required for building structures, such as facade insulation, water-resistant insulation, doors and windows, wall and floor coverings, electrical and mechanical fittings, etc., are installed in accordance with the client’s requirements and relevant regulations during design and construction.
The ISB® Building System components are categorized into three main groups: I. wall elements, II. floor elements, and III. reinforcement. The constituent elements of wall and floor elements, including shell elements and insulation elements, are determined based on their materials and dimensions, defining the types of ISB® Building System. While the ISB reinforcement elements remain consistent regardless of the type of wall and floor elements.
Within each main category of the ISB® Building System, multiple types of elements are manufactured, simplifying construction processes and reducing waste generation.

The General Principle of the Structure
The ISB® Building System operates on two fundamental principles, each integral to its innovative approach to construction:
1. Primary Principle:
The primary principle revolves around the load-bearing structure formed by the fabric reinforced grid. This grid is meticulously integrated among the components of the ISB® Building System after concrete pouring. It serves as the backbone of the structure, providing robust support and stability.
2. Secondary Principle:
Complementing the primary principle is the secondary principle, which focuses on insulation and creating an airtight shell for the building. Remarkably, this is achieved without the need for additional ancillary items. Instead, the building construction itself is formed by the elements of the ISB® Building System. This approach ensures efficient thermal insulation and airtightness, contributing to energy efficiency and occupant comfort.
By seamlessly integrating these principles, the ISB® Building System delivers structures that are not only structurally sound but also optimized for energy performance and environmental sustainability.
Environmentally Friendly Production
At the core of the ISB® Building System is a commitment to environmentally responsible practices throughout the production process. One key aspect of this commitment is the utilization of waste generated during production in the construction of buildings.
Throughout the manufacturing process, efforts are made to minimize waste generation and maximize the efficiency of resource utilization. Any waste generated during production is carefully managed and repurposed to contribute to the construction of buildings using the ISB® system.
This approach aligns with sustainability principles, as it reduces the environmental footprint associated with both production and construction activities. By recycling and repurposing waste materials, the ISB® Building System minimizes its impact on the environment while simultaneously enhancing the sustainability credentials of the structures it constructs.
Specific Features of the ISB® Building System
The ISB® Building System boasts several unique features that set it apart from conventional construction methods:
1. Innovative Integration
The system ingeniously combines the benefits of traditional silicate-based and lightweight construction systems. Certain elements of the kit serve as multi-purpose components within the full load-bearing and structural system, enhancing efficiency and versatility.
2. Integrated Insulation
Most building components of the ISB® Building System come equipped with insulation materials, serving as permanent formwork modules during concrete pouring. This integration results in a complex load-bearing and structural shell, forming a module family capable of producing a thermal shell with self-supporting rigidity.
3. Materials and Production Methods
Formwork modules of the ISB® Building System are prepared using materials such as porous concrete (or a combination of porous concrete and EPS alloy), along with steel and special concrete for the monolithic frame. Production methods range from craft production to automated production lines, requiring only labor force and traditional hand-tools during installation.
4. Energy Efficiency
The system meets current building energy standards without the need for additional thermal insulation. However, higher energy demands can be easily accommodated either by adding related insulation materials or by utilizing ISB® Poro 400 units with advanced thermal parameters.
5. Regulated Use and Training
Utilization of the system’s modules is governed by simple yet rigorous technology instructions for design and construction. Training is provided to designers and installers by engineers, with successful candidates receiving certification as ISB® Special Designers or Professional Contractors. This certification is valid for three years and renewable upon completion of renewal training.
6. Customization and Fine-tuning
The system allows for fine-tuning of structures, such as adjusting the size or position of basic structural ribs, to meet specific project requirements and preferences.
7. Incorporation of Quality Materials
Subsequent developments of the ISB® Building System aim to incorporate controlled quality clay with high purity, as well as desert sand, among its basic materials, further enhancing its performance and sustainability.
These features collectively contribute to the versatility, efficiency, and sustainability of the ISB® Building System, making it a preferred choice for modern construction projects.
