Wood Durability
Wood Durability for Log Cabins and Pods
The table below explains the durability of timber that is left below ground for water and rot to penetrate in the worst possible conditions. as an example soft wood that most pods are made of are classed as NOT DURABLE by TRADA.
Durability is the measurement of how long specific species of timber would last is a 50mm x 50mm cross section was left in the ground unprotected. An untreated Oak beam, which is classed as “durable”, for example, will last 15-25 years depending on environmental conditions.
The following scale of durability was outlined by the TRADA – the Timber Research and Development Association.

Let’s take a pod that is completely encased in beautiful Siberian Larch. It (Siberian Larch) has a very high resistance to decay, and rarely shrinks or twists. It also has superb acoustic and thermal properties. Siberian Larch is classed as moderately durable, and does not require treatment for external use. Its expected lifespan is around 20+ years …
The better you treat your POD the better it will treat you!!!!!
