Norrsken Windows

Supplier of high-performance triple and double-glazed composite windows and doors.

Norrsken specialises in high-performance double and triple-glazed timber windows and doors with a powder-coated aluminium exterior cladding. Composite windows offer an excellent compromise between the performance, warmth, and classic charm of timber, and the contemporary appeal of aluminium. Their composite windows maximise both the durability and thermal performance of timber and the sleek appeal of aluminium.

Composite Windows and Doors

Customers typically use Norrsken windows on new build projects as part of a high-performance thermal envelope or for substantial renovations where the building performance will be significantly upgraded. Norrsken are passionate about conserving energy. Their triple-glazed products have been designed from the ground up to deliver incredible performance, and several models are suitable for Passive standard and low-energy projects. With U-values in the region of 0.8 W/(m²K) or better (and some as low as 0.6 W/(m²K) on both windows and doors, they are among the best performers on the market.

Composite windows offer unrivalled stylistic options. Orders are completely bespoke – from the glass type and colours down to the window mechanism. Hinge systems can be configured in several ways. The frame dimensions, thickness, shape, and opening system are all individual to each order. Alu-clad products can be finished in any RAL colour. Norrsken also supply and install a range of bespoke sliding and bi-fold doors, designed to offer unrestricted views and allow natural light to flood a home without compromising on security or energy efficiency. 


In an industry where quality of service is not universal, Norrsken takes customer satisfaction very seriously. Scores of glowing reviews testify to their dedication. Trusted installation partners have been carefully selected to ensure that their workmanship is aligned with Norrsken’s own exacting standards, and they assess this regularly through site visits and customer feedback.
