The distinction between these species primarily lies in natural durability, appearance, and stability. Cedar (Western Red Cedar): This is a naturally stable wood, renowned for its exceptional resistance to insects and rot thanks to its tannins. It is considered durable wood, which is its main advantage over other species. Fir and Spruce: These two species (often grouped in the SPF category: Spruce-Pine-Fir) are more economical and very popular options. They offer distinct grains and look while being classified as non-naturally durable softwoods. They possess good structural resistance properties but must be protected from the weather. Although fir and spruce require more protection than cedar, Maibec uses high-performance, factory-applied finishes to guarantee the durability and integrity of all these species against the rigours of the Canadian climate.
