Douglas fir as terrace wood

They are still popular: Douglas fir wood decking. Whether you really are such a good choice, and which advantages and disadvantages you have to accept in Douglas wood planks, you will find in detail in this post.

Opportunities for terraced construction

For the construction of a wooden terrace you can choose different types of wood - for the substructure as well as for the floorboards.

  • tropical wood species, such as Bankirai
  • larch
  • acacia wood
  • Oak wood

Each of these options has its advantages and disadvantages, and of course this also applies to the Douglas fir.

Pros and cons of Douglas fir

When building terraces you should thoroughly weigh the pros and cons of each type of wood against each other, if you decide. Douglas fir also has some considerations here:


Douglas fir wood is a softwood, and thus relatively inexpensive. With decking you often get the running meter from as little as 4 - 5 EUR. Here other types of wood can hardly compete. Douglas fir is also relatively tough and has - for a softwood - quite good strength properties.

Possible disadvantages of Douglas fir wood

Douglas fir wood has only limited durability - the DIN EN 350-2 classifies Douglas fir wood only in the resistance class 3-4. This means that although the decking can withstand occasional humidification, it should definitely be well protected. Douglas fir wood is also not completely resistant to fungal and insect infestation and tends to graying. In addition, the wood is soft and coarse-grained, and can be damaged at higher loads. In warm weather it can also come out sticky resin - which can also be very disturbing.

Disadvantages at a glance
  • only mediocre durability
  • Protection against pests and against graying necessary (must be repeated regularly)
  • mechanically not highly resilient
  • possible resin exit

Problem tropical woods

Many high-quality tropical woods are in accordance with the DIN in resistance class 1 and are therefore completely durable, very hard and stable even without treatment (often twice as hard and heavy as oak) and have a very long life. The use of tropical wood species, however, brings with it quite a few problems that go beyond the mere difficulties of working very hard wood.

Tips & Tricks

Of course decking is always about the price - but you can win with more expensive woods, because the so-called "life" of wood used in high resistance classes is often 2-3 times as long.
