FINGER-JOINT Edge glued Radiata Pine Panel
Solid single layer wooden board conformed by pieces of Radiata pine wood reduced longitudinally but assembled by the joint known as finger-joint enabling the wood to reach the length requested by the client. Afterwards, the pieces of wood are connected and glued together edge to edge and or on edge based on an aqueous dispersion-based adhesive of polyvinyl acetate.
The manufacturing process is completed by longitudinal cut of the piece to normalized length in addition to the item’s sanding. The international term that used is the acronym SWP (S = solid; W = wood; P = panel).
A/A Grade: both faces are clear, free of knots. This is reason why the strip is cut into small pieces to afterwards join them together again along the longitudinal plane: the result is a completely clean board.

Conservation and Storage
Our experience with Radiata pine and finger-joint panels made of this raw material allows us to know the possible modifications or damage that the product might suffer in the event that a series of recommendations regarding basic conservation and storage were not taken into consideration to preserve its durability and stability.
In wanting to avoid warping of the panel or edging of the strips that are at the edges we suggest the following recommendations:
- Do not subject the plank to sudden temperature and or moisture changes. Wood is sensitive to variations in the stability of the atmosphere surrounding it.
- Avoid storing the panels of wood in direct contact with floors and walls.
- Keep the original packaging, which were provided with the goods whether it be one by one or altogether, avoiding contact with the atmosphere for a prolonged period of time if the goods have not been rearranged or moved from the initial positioning – once the piece which is going to be put to use has been removed.
- Apply varnish, lacquer, paint or similar chemical treatment or equivalent that enhances the resistance of the panel/board and is not incompatible, in accordance with the fact sheet provided by the manufacturer, with the wood in itself or the adhesive used to glue.
