Acetylated timber

Timber acetylation increases the durability of wood by reducing its ability to absord water.  The acetylation process changes the free hydroxyls within the wood into acetyl groups. This is done by reacting the wood with acetic anhydride, which comes from acetic acid (known as vinegar when in its dilute form). This is a non-toxic process of widening the variety of applications for timber in construction projects.

In the above film MAKAR have used acetylated timber produced by Accoya Wood in the foundation construction of a two storey house.  The result is a system which has potential to significantly reduce carbon emissions from the construction industry.
