Panels should be stored in a covered and dry place and to be kept flat and level on dry rafters keeping them off the ground. Spacing between rafters is to be calculated to be suitable to the thickness and the nature of the stored panels. In case of storage in several piles, align the supports with the long side. On a construction site, plan for shelter or for covering for the panels that is simultaneously water repellent and permeable to water vapor.


Use in compliance with current industry, safety, and building codes – DTU 36.1.
In order to ensure resiliency of the completed work, compliance with implementation and maintenance requirements below must be respected:

Preparation of panels prior to installation

In the workshop, apply protective, fungicidal, anti-blue stain, and water repellent treatment, on the face of the panels and on the edges. Check that the product ensures the 3 properties and is suitable for use on plywood. Fungicide + water-repellent preservatives in an organic solvent phase are recommended because they are more penetrating.

Panel installation

Install panels on battens in ensure proper ventilation to the counterface, the battens must be staggered for proper air circulation. In the case of insulation installation, make sure the battens are thick enough to allow sufficient airflow between the insulation and panelling in order to avoid moisture. On the exterior (Elegia), when covering vertical walls, the panels must be installed so the grooving is vertical.

Fastening the panels: the maximum distance of the supports must not exceed:
- 60 times the thickness of the panel in the case of vertical installation, with supports perpendicular to the panel grooving, - 50 times the thickness of the panel in the case of horizontal or oblique installation, with supports perpendicular to the direction of the panels. The first and the last batten are placed at about 5 cm from the ground, the ceiling, and any other edge of the wall section. Use twist or ring-shank nails, nailing every 15 cm.


For application in exterior or damp settings, ROLPIN LAMBRI plywood, having been treated with a fungicide, anti- blue stain, and water repellent must then be finished using opaque finishes (paints) or transparent or semi transparent finishes (stains). These finishes must be applied immediately after installation according to the manufacturers’ requirements with a minimum of two layers on a new structure.


In order to ensure resilience in exterior or damp setting applications, ROLPIN LAMBRI plywood requires maintenance of the exposed, visible face by applying a fresh coat of paint or stain. Maintenance intervals depend upon the quality of the product and the exposure of the panels.


Panel dimensional tolerances are as follows

They are in compliance with standard EN 315 requirements :

  • Length/width dimensional tolerance: ±3.5 mm
  • Straightness of edges and squaring: 1 mm per linear metre
  • Thickness tolerance according to NF EN 315 standards
