A unique natural product
For veneer of natural strains (organic veneer OV) only the best wood stems are used. During the production process the wood is steamed which gives the veneer a specific colour. After cutting the wood is dried and bundled in veneer-books of 24 or 32 sheets. The veneer books are in shape of a stem again. Wood is a unique living material. Growth characteristics such as knots, brushes, mirror, moiré and also colour and structural differences accentuate the natural product. Veneer is also made from rotary cut veneer in which the sheets are made gluing them together and then cut again. This reconstructed veneer, also called engineered veneer (EV) is available as an imitation of natural OV veneer and in fantasy decors. At EV veneer the growth characteristics are hardly present.
Veneer quality – choice depending on application
There is no standard quality for veneer. Veneer should technically okay. Taste, however, remains a personal experience. Lambri uses clear definitions relating to the quality of OV veneer:
- A + quality stands for the best part of the stem, uniform in colour and uniform in wood structure. Growth characteristics barely visible. Application: custom panels for walls.
- A quality means great attention to colour and structure. Growth characteristics partially visible. Application: Custom Panel ceilings/furniture and plates for wall panelling.
- AB quality is the economic application where differences in colour and structure are visible on the plate. Growth characteristics are visible. Application: sawing panels and smaller furniture parts.
Some knowledge related to veneer helps to make the right choice.
The choice of the structure of the veneer is important:
Dosse: a flamed structure which arises when the half stem is cut as from the outside
Quartier: a straight-grained structure that appears when a quarter of the stem is cut.
Many wood types are available in both dosse and quartier. Certain wood species are only in dosse or only in quartier structure.
Veneer processing – professional knowledge required
The department veneer is a separate discipline within Lambri . The veneer is worldwide bought by own specialist veneer producers certified at PEFC/FSC. About 40 wood species are permanently in stock. The processing of veneer to decorative plate material requires professionals and advanced machines. The veneer is sorted by colour and structure, and then glued together.
A choice from four joint methods is:
“bookmatched”,where the veneer successively turned from the veneer book for a continuous veneer structure
“slipmatched”, where the veneer is not turned and therefore there is no continuous structure. Gives a pretty specific image. Usually only at pure quartier veneer structure.
“mismatched”, in which veneer from different books with different width veneer is glued together to create a “natural panel”-effect. “mismatched – colour matched” in which veneer books of the same colour, different width and structure, are added randomly to each other. This gives a natural uniform picture in walls with little colour difference.
