Integrated into the glazing edge of multi-pane IGUs, Swisspacer Air is designed to ensure continuous pressure equalisation with the environment and mitigate climate loads.

Insulating glass units with Swisspacer Air have been recognised as regulated construction products on the German market since 2019 and are now available with CE marking, via a European Technical Assessment (ETA), thanks to a collaboration with Glassolutions.

As a small component in the glazing edge of insulating glass units, Swisspacer Air can minimise damage that can be caused by excess or negative pressure in the cavity between the panes – for example as a result of height differences during transport or due to climatic loads. The permanent pressure relief ensures that the insulating glass unit retains its function and quality in the long term.

According to Swisspacer, the risk of curved panes, glass breakage and premature ageing due to excessive stress on the glazing edge is significantly reduced.

“Many insulating glass manufacturers and window manufacturers sell their products throughout the EU,” said Sarah Sattler, sales and marketing manager at Swisspacer. CE labelling is a prerequisite for the unrestricted movement of goods within Europe. And it gives building owners the certainty that a building product functions perfectly.

“For us, it is a matter of course to support our customers in making the most of the market potential for pressure-equalised insulating glass units,” she continued. “That’s why we worked with our colleagues at Glassolutions to get the process up and running – and are delighted to have the first ETA for pressure-equalised insulating glass units reviewed and approved by the EU.”

With the Caluwin online tool, insulating glass manufacturers and window manufacturers can already check whether the use of Swisspacer Air can achieve the pressure equalisation required to prevent damage from climatic loads. And this can be done individually for specific insulating glass units and for given boundary conditions such as climate zones and differences in height during transport.
