Treated wood can be harmful to the environment, especially
the bottom-of-the-range items, which after some time
may lose any product that is poorly fixed.
By using the correct concentrations
and optimally applying the treatment, there is no
danger, even during direct contact with the treated
wood.
This is why it is necessary
to select high-quality wood for outdoor use, which
is regularly checked by independent organisations.

WHAT DOES THE IMVAC
LABEL COVER?
The IMVAC label is a quality label granted to the
impregnation plants which use the autoclave. In order
to guarantee a constant, high quality standard, the
IMVAC label management group carries out checks of
an essentially technical nature on the activities
of the plants which display the label.
This plant checking system is based on a dual procedure:
self-checks combined with permanent external checks.
The external check is conducted by the Centre Technique
de l'Industrie du Bois - CTIB (technical centre for
the wood industry).
Four points are systematically monitored:
- The wood,
in terms of quality and residual humidity;
- The product,
which has to comply with the product stated by the
plant;
- The treatment
solution in terms of concentration, percentage composition
of active ingredients, physical and chemical qualities,
etc.;
- The process,
both in terms of the state of the installation and
the application of the solution and the penetration
of the solution in the wood and the retention achieved
in the product.
Furthermore, the use of treated wood contributes
to the reduction of forestry felling.
The T.P.B. S.A. industrial wood treatment plant
is ATG035
-CTB-B+
approved.
