High-performance warm edge technology for competitive window systems.
Swisspacer warm edge spacers are a key component in high-performance window systems. By significantly reducing thermal bridging at the glazing edge, they help optimize Uw values and improve the overall energy efficiency of insulating glass units. This supports window manufacturers in meeting increasingly stringent building regulations across Europe and international markets.
Beyond thermal performance, Swisspacer contributes to improved life cycle performance of windows. With a reduced carbon footprint and verified Environmental Product Declarations (EPDs), our spacer systems provide reliable data for building life cycle assessments and sustainability certifications such as LEED, BREEAM and DGNB. This enables compliance with evolving environmental standards while strengthening the long-term competitiveness of your window systems.
Caluwin: Compare window performance
Caluwin is our calculation tool for comparing insulating glass and window configurations with different spacer bar models. It helps you quickly evaluate Uw values, glazing-edge performance and interior surface temperatures to assess condensation risk and optimize thermal performance. Results can be documented for specifications, customer consultations and compliance with energy-related building requirements across Europe and international markets.
Optimize your Uw value
With Swisspacer warm edge technology, you can measurably improve the Uw value of your window systems without modifying frame construction. This supports compliance with current and future energy regulations and enhances the overall thermal classification of your products.
Swisspacer lowers the carbon footprint of your windows
Environmental regulations increasingly focus on whole-building life cycle assessment rather than thermal performance alone. For window manufacturers, this requires reliable and transparent environmental data.
With verified Environmental Product Declarations (EPDs) for Swisspacer spacer systems and Georgian bars, we provide the data basis required for LCA calculations and sustainable building certifications.
Compared to conventional aluminum spacer systems, Swisspacer contributes to improved CO₂ performance at component level, supporting more sustainable window solutions.
For projects with high design requirements, Swisspacer Ultimate | Nyxé combines an all-black appearance with recycled content — supporting both aesthetics and sustainability goals.
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.
Aesthetics for your windows
In addition to their excellent performance and carbon footprint, our spacers are also the best choice for achieving a high-quality and coherent design of your windows, down to the smallest detail.
With 17 different colors, we have a wide color selection. From our standard colors of black, titanium gray, white and brown to special colors like grass green, sapphire blue or pastel yellow. We offer the right design for every window construction.
Pressure equalization for reliable insulating glass units.
Swisspacer Air integrates a pressure compensation system directly into the insulating glass unit. It reduces stress caused by altitude differences, transport and climate changes - helping to prevent glass deflection and seal strain.
Ideal for:
High-altitude installations
Export projects
Modular and mobile buildings
Large glazing units
No redesign of your window 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.
