Why wood fibre insulation is not a food source for termites

Wood fibre insulation is not a source of food for termites for two main reasons.

​

In the process of making wood fibre, the wood undergoes a chemical and anatomical transformation. During the firing phase of the fibres at high temperature, the sugars of the wood (xyloses) are extracted from the fibres and removed with the cooking water. In the absence of nutrients, wood fibre is of no interest to boring insects.

These characteristics are recognized by a standard (NF EN 335-3).
