To enliven your façade shutters made in Okoumé sélection from the Joubert Façade Premium range will provide you with aesthetic appeal, resistance to bad weather, long life, and small size variations.

This entirely Okoume plywood intended for high quality work in exterior joinery was originally created for shutters in the Veneto region of Italy and is now having real success in the South of France.

What are the optimum conditions for storing panels?

Storing plywood panels requires very little care. They should be placed flat, preferably away from damp, spacing out the studs by 50 cm, and aligning the intermediate studs in the piles.

In fact, storage in a temperate area, without significant variations in hygrometry, makes it possible to prevent moisture regain which causes the panels to warp.

Is joubert plywood subject to the ISPM 15 standard?

The ISPM (International Standard for Phytosanitary Measures) No. 15 standard stipulates that processed wood packaging, such as plywood, is exempt from marking requirements.

In fact, with the process used the various production stages subject the veneers and plywood to very high temperatures for drying and baking under a press and therefore the insects and fungi on the finished panels are removed.

What is the difference between a WBP and a CTB-X panel?

The WBP - Water Boil Proof - denomination is no longer valid insofar as the foreign standards on which it was based have been replaced by new European standards, which define the requirements for gluing plywood. In particular, plywood for exterior use must correspond to Class 3 gluing in accordance with the standard, NF EN 636.

NF Extérieur CTB-X certification is not compulsory. It is a voluntary approach on the part of the manufacturer to certify the quality of its products. The characteristics demanded by this quality mark go beyond the requirements of the European standards.

The NF Extérieur CTB-X quality mark provides the user with the guarantee of conformity for the quality of the exterior gluing and the mechanical characteristics of the plywood intended for exterior use.
