LATEST GENERATION TECHNOLOGY FOR SUSTAINABLE PROJECTS
LATEST GENERATION TECHNOLOGY FOR SUSTAINABLE PROJECTS
TechDaal enclosure systems are developed based on rigorous technical detailing, designed to ensure structural stability, controlled airtightness, and long-term correct performance of the building assembly. Each solution is defined layer by layer, using certified and fully compatible materials, each with a clearly assigned role in load transfer, vapour control, and structural protection. The enclosure details integrate the lightweight steel structure, fixing systems, protective layers, and finishes, enabling precise and predictable execution. These solutions are thoroughly documented to support correct on-site implementation and to maintain compliance with current quality and durability requirements.
