The South Tyrolean company Vitralux was responsible for the exterior glazing. With frameless glazing, slim profiles and barrier-free transitions, the VITRALIGHT system creates seamless connections between the interior and the surrounding mountain landscape – both in the suites and in the spa area.

Performance down to the last detail

The project also excels in terms of energy performance: triple safety insulating glass with a Ug-value of 0.6 W/m²K enables Uw-values below 0.8 W/m²K in combination with VITRALIGHT. The Swisspacer Ultimate warm edge spacer bar used reduces heat loss at the glazing edge and prevents condensation – a key advantage, particularly in the wellness area.

Sustainability also played a central role: the aluminium profiles used consist of at least 75% recycled aluminium. In this way, the project combines transparent architecture with comfort, energy efficiency and responsible material use.

Thiery brings extensive experience from various positions within Saint-Gobain. Most recently, he served as Marketing Director at Formula, where he was responsible for marketing, communications, innovation, digital and IT. His background also includes roles in R&D and business development in the insulation sector.

With his broad expertise, Swisspacer is further strengthening the connection between customer focus, innovation and market development. Together with the team, Thiery will continue to develop marketing and sales with a clear focus on customer needs and value-added solutions.

Swisspacer thanks Sarah Sattler for her strong commitment and her contribution to key initiatives, particularly in digitalisation and growth, and looks forward to working with Julien Thiery in his new role.

The façade plays a central role in this concept. More than a visual design element, it contributes significantly to daylight comfort, thermal performance and energy efficiency. To meet the project’s demanding architectural and environmental requirements, high-performance solar control glazing from Saint-Gobain Glass was combined with Swisspacer Ultimate warm edge spacer bars.

The glazing solutions help create bright, comfortable interiors while reducing unwanted heat gain and supporting lower energy consumption. Swisspacer Ultimate further enhances the performance of the insulating glass units by reducing thermal bridging at the glass edge. This contributes to improved energy efficiency, greater indoor comfort and a reduced risk of condensation.

Thanks to the intelligent combination of Saint-Gobain Glass and Swisspacer solutions, EMBLEM achieves a strong balance between design ambition and sustainable performance. The project has been awarded BREEAM certification with an “Excellent” rating, underlining its high standards in terms of energy efficiency, comfort, durability and environmental responsibility.

EMBLEM shows how modern façade solutions can support ambitious architectural visions — creating buildings that are not only visually distinctive, but also efficient, comfortable and designed for the future.

Local production offers clear benefits for both customers and the environment. Shorter transport routes improve delivery times and help reduce transport‑related emissions. At the same time, manufacturing in the region enables solutions that are specifically tailored to local climatic conditions and market‑specific window and façade systems.

The new site is the result of a coordinated project within the Saint‑Gobain network. Swisspacer contributes its long‑standing expertise in the development and production of warm edge spacer systems, while Saint‑Gobain Glass India provides in‑depth market knowledge and close relationships with local partners. Together, they create an integrated offering that supports energy‑efficient insulating glass solutions and underlines Swisspacer’s role as a globally active, market‑oriented specialist.

A key focus of the renovation was the restoration of the original timber windows. Specialists in historic window refurbishment carefully upgraded the existing frames to meet today’s energy‑efficiency standards without altering their historic appearance. Modern insulating glass units equipped with Swisspacer Ultimate warm‑edge spacers were integrated into the glazing edge, significantly improving thermal performance while remaining visually discreet.

The upgraded glazing achieves a Ug value of around 1.4 W/m²K, a balanced solution that meets both conservation requirements and economic feasibility. In combination with Swisspacer Ultimate, the glazing edge reaches excellent Ψ‑values, reducing heat loss and lowering the risk of condensation—critical aspects for historic windows with limited tolerance for construction errors.

Beyond energy efficiency, the project also enhances year‑round comfort. Automatically controlled fabric awnings provide summer heat protection, while the improved glazing supports a more stable indoor climate. The renovation shows how even small components such as the spacer bar play a crucial role in delivering sustainable performance in heritage buildings.

Today, the Lavater School stands as a reference project for sustainable heritage refurbishment—proving that advanced technologies like Swisspacer warm‑edge spacers can successfully bridge the gap between monument preservation, energy efficiency and modern educational use.
