The Douglas fir originally originates from western North America, where in the coastal areas it can grow up to 100 m tall under optimal growing conditions. It is usually 50-65 m high when felled at the age of approx. 80 years. We mainly get Douglas fir from Germany, and we only use certified wood. Douglas can be recognized by its appearance with pale green needles and – depending on the age of the tree – grey-green to grey-brown bark.
With constructive protection, the wood is very durable. The durability is like Scots pine – and twice that of red spruce. Constructive protection means that you design and build in such a way that the wood is ventilated and water is diverted away, so that the wood has the opportunity to dry out.
