Energy-efficient wooden doors and windows for every home

At Sparwindows we produce our wooden windows and doors in slow-growing Nordic pinewood. Slow-growing pine contains less air, which ensures the best quality wood – still at the same low prices.


In the following, you can read more about pine and how the timber is used in the production of furniture, paper and building materials, as well as why we only use slow-growing pine from colder Scandinavian regions in our production of windows and doors. 

Pine belongs to the genus Pinus, which consists of around 100 different species of coniferous trees. The primary characteristic of the genus Pinus is that the trees are green all year round, their needles are found in small shoots of 2, 3 or 5 needles and that they have different types of cones. The genus Pinus is widespread all the way from the northernmost regions of Norway down to the Equator, where the genus is stopped from spreading by huge areas of sand and desert.

What is pine wood and why is it special?

Pine belongs to the Pinus genus, which includes around 100 species of evergreen coniferous trees. Known for their resilience and beautiful grain, pine trees grow across vast regions—from the cold forests of Northern Norway to warmer areas closer to the Equator.

However, not all pine is created equal when it comes to joinery.


The benefits of slow-grown nordic pine

The best pine for wooden windows and doors grows slowly in the cold climates of Northern Europe. These ideal conditions create:

  • Narrow growth rings = denser wood
  • High heartwood content = stronger, more durable timber
  • Better resistance to weather, decay and pests

In contrast, pine from central Europe grows too quickly, resulting in a softer, less stable material.


Naturally Durable – With Added Protection

Thanks to its natural resin channels, pine has built-in resistance to fungi and moisture. But to ensure maximum durability, we apply:

  • Wood preservation treatment – deep protection against decay
  • Factory-applied water-based paint – protects your windows and doors from rot, UV, and harsh weather

You’ll receive products that are ready to install, perfectly painted (if choosen), and built to last.

Long-lasting quality with UKCA marked and 10-year warranty
