Bug resistant

When using wood outdoors, one of the major aggressions you have to guard it from is xylophages insects.
The most common are beetles and xylophages larvas.
Retified wood doesn’t have any chemical insecticide but the heat, when modifying its components, makes it uneatable for many types of grubs.
Retification, because it modifies the “sugar” contained in the wood (in particular the hemicelluloses) which xylophages insects crave on, deprives the wood of any nutritive aspect.

Termites are quite particular. Retified wood, just like plaster or concrete still risks attacks of termites looking for wood. However it remains far less attractive for them than non treated wood and can be, if necessary, treated with anti termite solution.

Resistant to biological attacks

A wood’s susceptibility to fungus is a key factor in its durability. The process of Retification considerably improves the durability of different local wood by the simple use of heat

There are three main categories of decay that is likely to affect wood: dry rot, soft rot and white rot.
These three types of decay are the result of fungi, all of which seek sugars and high humidity that are essential to their development.

Retification prevents the fungi from oxidizing the cellulose by modifying the structure of the wood, therefore depriving the fungi of nutrients. Furthermore, Retification considerably lowers the equilibrium moisture content of the wood, diminishing the supply of water necessary for their development.

Dimensional stability

Wood differs in dimension in relation to the rate of equilibrium moisture content. In other words, assorted woods contain variable amounts of water.
The constituent in the wood that is primarily responsible for these variations is the hemicelluloses, which is particularly responsive to water. Retification reduces the number of these cells, therefore lowering the wood’s capacity to hold water. As a result the wood is less likely to swell due to the presence of water.
Moreover, by reaching the high temperatures that are necessary for vitreous transition, Retification diminishes the wood’s development limitations as well as its rigidity.

Mechanical resistance

Heating wood at high temperatures modifies its structure, and consequently its mechanical properties.
Retification is a specific and patented process that allows us to improve the durability and stability of the wood while at the same time limiting the loss of mechanical properties.
Only a perfect mastery of the temperature and atmosphere inside our reactors allows us to preserve the essential mechanical performances of our products.
An important aspect which is often forgotten in considering the mechanical resistance of a wood is its original quality. RETIwood products are chosen with care from amongst the highest quality of wood from each species, and henceforth monitored from the time it is delivered until the last stages of the process.
It is this expertise in wood treatment that allows us to offer outdoor wood of exceptional quality.
