High-performance glazing edge solutions for energy-efficient façades and windows for your architectural projects.
Swisspacer warm edge technology enhances the thermal performance of insulating glass units by reducing thermal bridging at the glazing edge. By optimizing Ψg values, Swisspacer contributes to improved Uw performance of windows and curtain wall systems — supporting compliance with increasingly stringent energy standards in international markets.
For architects and façade designers, this means greater design freedom without compromising building performance.
Design with measurable performance
The glazing edge significantly influences overall thermal behavior, condensation resistance and interior surface temperatures. By improving edge performance, Swisspacer supports enhanced comfort levels and reduces the risk of condensation at the perimeter of the glass.
This is particularly relevant in:
- Large façade elements
- Floor-to-ceiling glazing
- High-performance curtain wall systems
- Passive house and low-energy buildings
These factors can be taking into consideration with our calculation tool Caluwin.
Refined aesthetics down to the glazing edge
Architectural quality is defined by detail.
Swisspacer spacer systems are available in 17 colors, including black, titanium gray, white and brown, as well as selected special colors. For projects with strong design focus, Swisspacer Ultimate | Nyxé offers a deep black appearance combined with recycled content - enabling clean sightlines and a coherent façade aesthetic.
Reliable environmental data for sustainable building concepts
Sustainable building design increasingly requires transparent life cycle assessment data.
With verified Environmental Product Declarations (EPDs) for Swisspacer spacer systems and Georgian bars, we provide reliable environmental information for building certifications such as LEED, BREEAM and DGNB, as well as for whole-building LCA calculations.
Compared to conventional aluminum spacer systems, Swisspacer contributes to improved CO₂ performance at component level — supporting environmentally responsible façade and window design.
Increasing living comfort with Swisspacer
Swisspacer helps to keep indoor temperatures at the edge of the glass pleasantly warm in winter. This prevents the formation of condensation and it reduces the risk of mold and bacteria growth. An important prerequisite for a healthy and pleasant living atmosphere. A study by the Passive House Institute confirms: The choice of a suitable spacer has a major influence on thermal comfort.
Integrated system competence
Swisspacer is part of the Saint-Gobain ecosystem, enabling coordinated glazing solutions in combination with high-performance solar control and low-emissivity glass. Together with façade manufacturers and insulating glass processors, this supports optimized glazing systems from center-of-glass to glazing edge.
Early specification of warm edge technology ensures consistent performance throughout the project lifecycle.
Pressure equalization for reliable insulating glass units.
Swisspacer Air integrates a pressure compensation system directly into the insulating glass unit. It helps balance pressure differences caused by altitude, transport and climate variations.
Ideal for:
High-altitude projects
Export façades
Modular and prefabricated buildings
Large-format glazing elements
No redesign of the glazing system required.
eLement, Athens, Greece: The LEED-certified office building in Athens surrounds a Mediterranean garden and, with its green roof terraces, appears very natural. The high energy efficiency of the surrounding glass facades is ensured by insulating glazing with Swisspacer Ultimate warm edge spacer bars.
Finstral supplied IGUs for the Santner Pass hut in South Tyrol.
Authentic reconstruction meets modern technology: With Retro78 windows from PaX and Swisspacer Ultimate, a listed building in Viersen was renovated for energy efficiency – combining historic charm with contemporary thermal insulation.
