Windows

What makes a window great? 

In our view it should:

  • Look Superb
  • Operate smoothly
  • Keep the cold and weather out
  • Keep the warmth in
...and keep doing all of this for a long time.

Here at Norrsken, we know from experience that finding windows that meet aesthetic, functional, and performance demands simultaneously can be tricky. Getting them competently fitted can be harder still. 

Our aim is to listen carefully to your brief and design requirements and provide products that precisely match those requirements. We also believe that you should be able to customise your windows – which is why we offer so many options. Check out Options for more information on the many choices available to you.

If you know the type of product you are looking for then go to our Product Selector to narrow down your choice and get specific technical details.

Construction Quality

The use of top grade, responsibly sourced, laminated, slow grown timber*, combined with tried and tested hardware prolong your window's life span for many years. Gaskets and insulated glazing units ensure air tightness and energy efficiency. Double and triple glazed units use Low-E glass with argon gas filling as standard. All of Norrsken's glazing units have warm edge spacer bars. This minimises heat loss around the edge of the unit.

Timber is finished with a multi-coat protection and has excellent durability with class leading surface quality. Aluminium clad windows add a protective layer of powder coated aluminium externally. This gives extended weather protection and near zero maintenance. 

Windows are available in any RAL colour and a wide variety of stains. The glazing can be divided with external glazing bars to match traditional fenestration with spacers in the glazed units giving the appearance of solid bars.

To choose windows for your project that match your requirements try our Window Selector.

The majority of windows fall into two basic opening types: Inward opening and Outward opening.

Outward Opening

Outward opening windows were originally developed for harsh climate conditions in Northern Europe and are the dominant type in the UK, Ireland and Scandinavia. As these countries experience more challenging weather than many other European countries, the outward opening window works well because strong winds tend to force it to close more tightly, improving its weather resistance.

Outward opening windows can be: top hung, side hung or fully reversible. Triangular, circular and semicircular fixed windows are also available.

Inward Opening

Popular across Europe, inward opening windows are now growing in popularity in the UK. While having identical build quality and similar thermal performance to outward opening windows, they have two distinct features:

  1. The opening sashes can be opened inwards for easy cleaning
  2. Larger opening sashes are possible with inward opening windows, as the hardware can typically carry more weight
Inward opening, tilt and turn windows work well for many homes because they can be tilted inwards for ventilation and turned, opening up to 90 degrees internally, making it easy to clean them from the inside.
