Deck of maritime pine or scots pine, which is treated in class 4 of impregnation.

In this type of modified wood, furfurilação (furfuryl alcohol impregnation, double vacuum chamber, by autoclaving / cylindrical boiler pressure) is a method to lead to a decrease in the equilibrium moisture content and increased dimensional stability wood, based on the introduction of \ that ultimately decrease the hygroscopicity of the timber.

This is a cheaper process than other types of treatment with an expected durability of around 15 years.

Available scots pine with 28mm thickness and 145mm width (lengths from 3 to 6 meters). Other dimensions under request.
