Slow-growing wood from the north: Douglas fir and Nordic spruce

Wood is a valuable renewable raw material that makes ecological sense. But when choosing wood, it is not just the variety that matters. Whether Douglas fir and spruce are finely flexible and resistant depends heavily on the growing conditions of the trees. Here we reveal why we only use Douglas fir and Nordic spruce from northern Europe.

The northern spruce differs only in its location from the common spruce, which is also widespread in Germany. High-quality spruce wood is very resistant and elastic at the same time . The wood, which is almost white and hardly grained after felling, darkens in a warm honey-yellow tone . It can be versatile use and is both as a Construction and construction timber and as a basic material for high-quality musical instruments. As with the Douglas fir, the location of the spruce also has an enormous influence on the quality. Nordic spruce stands for the best wood with excellent properties in terms of workmanship and durability.

To understand, how good wood quality is created , it is important to Growth of the tree during a year. The Annual rings of a trunk not only indicate the age of a tree. You can also take part in them read the quality of Douglas fir and Nordic spruce .

• In the Spring forms the cambium in Douglas firs and Nordic spruces, the growth layer directly below the bark, large wooden cells that grow inwards.
• This so-called early wood you can tell by the very light color . It connects directly to the darkest spot on the outside of each annual ring.
• Unfortunately, early wood is very soft . Therefore, a large proportion of early wood reduces the quality and deteriorates the properties in the area of processing and service life.
• Due to the lower water supply in summer and lower temperatures in autumn Wood growth decreases over the course of the year .
• Douglas fir and Nordic spruce now form the considerably smaller-celled and firmer late wood .
• That Late wood is the wood that gives the tree its strength and the wood Resilience .
• You can recognize late wood by the darker color .
• In the Winter Douglas fir and Nordic spruce growth completely .
• In the next The cycle begins again in spring and another annual ring is created.

In Scandinavia, Spring and summer very short . That's why Douglas firs and Nordic spruces grow a lot there slower than under local weather conditions . In addition to the barren conditions, which allow the tree only short growth periods, the conifers have to withstand the stresses of wind and weather. This leads to an excellent quality of the wood. Compared to trunks grown further south, the wood of Douglas fir and Nordic spruce firmer, more resistant, more elastic and more durable . And this makes it the ideal raw material for high-quality garden sheds, saunas and pavilions, pollutant-free children's play equipment and robust carports.

Treating Nordic Spruce

Nordic spruce wood takes only a small amount of water on and does not tend to crack . In addition, the slats and posts do not warp if they have been sawn correctly. Therefore, it is advisable to buy Nordic spruce and products made from the material only in specialized shops. However, Nordic spruce wood also has a weak point: like all wood species that do not come from the tropics, the renewable raw material tolerates waterlogging and moisture poorly. Therefore, it makes sense to have a Climbing frame made of Nordic spruce to be treated before construction . This allows you to reach all sides of the various components. Here's how to do it:

• Handle all parts before assembly with a primer .
  
  

• Paint your children's playhouse or the climbing frame after assembly with a open-pored glaze or an opaque protective varnish .
  
  

In our online shop you will find Nordic spruce wood as a building material for many different garden sheds, carports and climbing frames. If you want to do without the primer, opt for one of our Models that are already pre-treated in attractive colours . However, the natural areas inside and on the cut edges must still be treated. Our aim is to provide you with high-quality accessories for your garden, which is why we deliberately choose high-quality Nordic spruce as a raw material.

Wood is a Renewable raw material , which only comes from European production Short transport routes . The low energy requirement during production provides a Valuable contribution to the environment and climate . Untreated natural wood offers biological, ecological and economic advantages.

Our garden sheds consist of solid Nordic spruce. This wood can be used very flexibly and absorbs only a small amount of moisture. This makes it an ideal building material for outdoor tool sheds and garden sheds. Nevertheless, additional wood protection is essential. We recommend our colour-pre-treated models or a later protective coating on your own.

The high quality of Karibu products starts with the Selection of wood . We only use uniformly sorted woods of Nordic spruce from the densely wooded areas of northern Europe. The trees grow very slowly there in short summers and long hard winters and form tight annual rings. This is the basis for Firm yet elastic and exceptionally resistant wood .

The Douglas fir originally comes from North America, but the excellent properties of the conifer are also convincing in European forestry. The wood of the Douglas fir is very straight and darkens over time in charming shades of red . The pronounced stripes of the annual rings make the wood Very attractive . In ideal locations, the Douglas fir grows slowly and forms a wood that experts call fine-grained. Because then the annual rings remain very narrow. You will find out why this is important later.

Not all wood is the same. At Karibu, we select only the best types of wood for our high-quality Summer houses , Pavilions , Sauna and Carports . We pay attention to the following points:

• Douglas fir and Nordic spruce
• from the forests of Northern Europe
• Hard, elastic and robust wood through long winters and short summers
• Short transport routes
• sustainable forestry
• Renewable raw material for climate and environmental protection
