|Storage||It is advisable to store the packages in a dry place, preferably flat and level on dry rafters insulating them from the ground. The spacing between rafters is to be adapted to the thickness and nature of the stored panels. When storing in multiple stacks, align the rafters in height. On site, provide shelter or cover the panels with a waterproof but vapor permeable coating.|

For a good behaviour of the works, it is necessary to respect the following implementation and maintenance prescriptions:
Preparation of the panels before installation
Apply in the workshop a protective primer, Fungicide, Anti-blue and Water repellent, on the face of the panels and on the edges. Check that the product used ensures the 3 functions and that it is suitable for use on plywood. Fungicide + water repellent products in organic solvent phase are recommended because they are more penetrating.
Installation of the panels
Lay the panels on cleats to ensure ventilation of the back surface, the cleats must be laid in staggered rows to allow air to circulate. If insulation is installed, adapt the thickness of the battens to allow for sufficient airflow between the insulation and the wainscoting to avoid humidity.
On the outside (Elegia), when cladding vertical walls, the panels must be installed in “vertical stripes”. Fixing of the panels: the maximum centre distance of the supports must not exceed :
– 60 times the thickness of the panel in the case of a vertical installation, with supports perpendicular to the direction of the grooves,
– 50 times the thickness of the panel in the case of horizontal or oblique installation, with supports perpendicular to the direction of the ridges.
The first and last cleats are placed about 5 cm from the floor, ceiling and any other edge of the wall.
Use twisted or notched nails, nailing every 15 cm.
For outdoor use or use in humid environments, ROLPIN LAMBRI plywood must be treated with a fungicide, anti-blue and waterproof primer and finished with opaque (paint) or semi-transparent or transparent (stain) finishes.
These finishes must be applied according to the manufacturers’ specifications with a minimum of two coats on new work, immediately after installation.
For outdoor use or use in a humid environment, ROLPIN LAMBRI panels require maintenance of the exposed visible side by applying a new coat of paint or stain.
The frequency of application depends on the quality of the product and the exposure of the panels.
|Dimensional tolerances of the panels|
They comply with the specifications of the EN 315 standard:
- Dimensional tolerance length/width: ±3.5 mm
- Straightness of edges and squareness: 1 mm per linear meter
- Thickness tolerance according to NF EN 315
