Norrsken specialises in high performance triple glazed timber windows and doors with a powder-coated aluminium exterior cladding. They are eco-friendly, energy efficient and designed for the UK. This gives you the warmth and beauty of wood internally with the minimal exterior maintenance of aluminium. Customers typically use our windows on new build projects as part a high-performance thermal envelope or for substantial renovations where the building performance will be significantly upgraded. Passive House projects are common in our client base. The Norrsken team is well-versed in working with Passive House project specifications. In an industry where quality of service is not universal, Norrsken takes customer satisfaction very seriously – a fact to which 95% 5-Star Trustpilot reviews will testify.
