About our range 

Norrsken products are categorised by their performance. 100-series products are double glazed, while 200-series products are triple-glazed. High performance, triple-glazed 300 and 400-series products are suitable for use in Passive House and ultra low-energy projects. 

Many customers use these high-performing windows and doors for non-Passive House projects too - triple-glazed windows should be used in in projects of all descriptions - not just Passive Houses. 400-series products have specific design features, certifications or other elements that take the top spot for performance and energy efficiency in our product range. Typical thermal performance details are available for all our products.
