What is meant by the "treatment threshold" for wood species?

The concept of "treatment threshold" for wood species refers to the minimum concentration of preservative that must be applied to effectively protect a specific type of wood from decay, insects, and other forms of deterioration. Different wood species have varying susceptibilities to damage, and this threshold ensures that the preservative treatment penetrates sufficiently to provide adequate protection.

Each species of wood has its unique characteristics and vulnerabilities, which means that some may require a higher concentration of preservatives to achieve the desired level of protection. By adhering to the treatment threshold, wood preservation professionals can ensure that the treatment is effective and prolongs the life of the wood by minimizing the risk of decay and damage. Recognizing and applying the appropriate treatment threshold is essential for maximizing the efficacy of wood preservation practices.
