Caring for Fir Wood

To maintain the strength and longevity of fir wood, it is essential to follow proper care and maintenance practices:

  • Regular Cleaning: Keep the surface of fir wood clean by regularly dusting and wiping it with a soft cloth.
  • Protection from Moisture: Prevent excessive moisture exposure by using appropriate finishes or sealants that provide water resistance.
  • Avoid Extreme Temperatures: Protect fir wood from extreme temperature fluctuations, as they can lead to expansion and contraction, potentially causing damage.


How strong is fir wood?

Most Doug-fir lumber is typically available in a dried and planed form, known as S4S (surfaced 4 sides). In terms of strength, dry Doug-fir wood has an ultimate strength, also known as the modulus of rupture (MOR), of 12,400 pounds per square inch (psi). It possesses a stiffness, referred to as the modulus of elasticity (MOE), of 1.95 million psi. Furthermore, it has a hardness rating of 710 pounds.

Is douglas fir expensive wood?

Douglas fir tends to be pricier compared to other softwoods like pine, with prices ranging from $4.24 to $14.00 per board foot. However, it’s worth noting that Douglas fir wood has a lower ranking on the hardness scale. Consequently, it is more susceptible to scratches and dents when compared to other types of wood.

How durable is douglas fir?

In terms of durability, Douglas fir sourced from North America is classified as moderately durable, with a durability rating of 3. On the other hand, Douglas fir grown in Europe exhibits a slightly higher range of durability, varying between 3 and 4, indicating slightly to moderately durable characteristics.


In conclusion, fir wood is renowned for its strength, making it a valuable choice for a wide range of applications. Its excellent mechanical properties, common uses in construction and furniture, and durability make it a reliable material.
