en.Wedoany.com Reported - Saint-Gobain has launched a new lightweight façade construction solution, specifically designed for buildings aiming to achieve the Passivhaus standard, further reinforcing its commitment to sustainable construction. Named ENVEOTHERM Integra Passivhaus + ECLAZ® ZEN ORAÉ®, this solution provides a complete, lightweight, and efficient lightweight façade system for high-energy-performance buildings, integrating different systems from the Group to meet four of the five fundamental principles related to the building envelope in the Passivhaus standard: thermal insulation, airtightness, thermal bridge-free design, and high-performance windows and doors.

This lightweight façade solution brings together certified and compatible components from different brands of the Saint-Gobain Group (Placo®, Isover, Weber, and Climalit®) in a unified system. This integration simplifies the project design and on-site construction phases, providing designers, developers, and contractors with a single point of contact for a complete lightweight façade solution, offering greater technical consistency and assurance of meeting Passivhaus requirements.

In terms of thermal insulation, thanks to the Placotherm® Integra lightweight opaque façade system incorporating Isover arena APTA mineral wool insulation, building energy consumption can be significantly reduced. For airtightness, through Isover's VARIO system, this lightweight façade solution is based on an intelligent bioclimatic membrane that regulates water vapor diffusion, helping to achieve a high level of sealing. The solution also meets the requirement for reducing thermal bridges through the webertherm ACUSTIC external continuous insulation system, minimizing energy loss and condensation risk. Simultaneously, thanks to the ECLAZ® ZEN ORAÉ® glass, specifically designed for double and triple glazing compliant with the Passivhaus standard, this lightweight façade solution also fulfills the high-performance requirements for windows.

In terms of sustainability, the materials used in this lightweight façade contain a high proportion of recyclable and natural raw materials. Taking ECLAZ® ZEN ORAÉ® glass as an example, it uses up to 64% recycled glass in its manufacturing process, significantly reducing the building's carbon footprint while maintaining the highest energy efficiency.
