Swisspacer Ultimate is reportedly the first warm edge spacer bar to be awarded a ‘Passivhaus approved’ certificate, following the Passivhaus Institute’s first ‘Passivhaus Components Awards’ for the most thermally efficient Passivhaus windows.
The awards took place in Aachen, Germany and recognised high quality, cost effective Passivhaus components. The results were based on tests to a detached house in Germany, and were open to all Passivhaus windows. Out of the 12 winning windows, eight reportedly incorporated Swisspacer Ultimate inside.
Swisspacer Ultimate was the first warm edge spacer bar to apply for ‘Passivhaus approved’ certification and is apparently the only spacer to be awarded the highest Class A classification. Swisspacer claims that the Passivhaus institute also confirmed Ultimate is best for energy efficiency in all climates.
Walter Schreiber, Swisspacer head of R&D attended the awards. He commented: “We were delighted so many winning Passivhaus windows featured Swisspacer. Over 60% of all Passivhaus windows have Swisspacer inside because it’s the best for thermal efficiency.
“The Passivhaus Institute is the world’s leading fabric-first approach to low energy buildings and the diamond standard for energy efficiency. We are particularly proud that Swisspacer Ultimate is the first ‘Passivhaus approved’ warm edge spacer bar – it’s great to have the recognition from such a prestigious institution.”
