18mm BB/BB Russian Birch Plywood (Class 2)
If you're unsure of the Grade you need, read this guide.
Russian Birch, also known as Baltic Birch, is generally regarded as being of a higher quality than standard Birch plywood. Russian Birch is very popular due to its combination of strength and visual appeal. Because of its unique construction, core layers of birch veneers form a void-free core.
Manufactured from a dense timber species Birch Plywood is a high quality, multi-ply hardwood panel, offering consistent strength, fine grain texture and ease of finishing. The multiple veneers which make up this plywood, increase its structural stability as well as offering a first-class finish. It is used widely in construction and other precision engineering applications. The grade of this board is BB/BB.
Constructed from many thin layers, Birch plywood has an excellent strength-to-weight ratio and is visually more appealing than standard plywood, making it suitable for a wide range of applications. These include tables, drawer parts, cabinets, bookcases, floors, packaging, skateboards, toys and more.
A versatile plywood that cuts and finishes well, these boards are light colour making them suitable for staining, but are commonly finished with clear lacquers or oils.
EN314-2 (bonding quality) and EN636 (durability & bonding) are ‘harmonised standards’ to clarify which plywoods can be used under different conditions. These tests determine the class that plywood can be specified under.
EN314-2 Class 3 Exterior conditions (exposure to weather over substantial periods or continuous exposure to relatively high humidity)
EN636-2 Class 2 This class is appropriate for protected external applications, it is also suitable for interior situations where the service moisture content is raised above the Class 1 level. EN636-2 (Class 2) Defines that the product contains timber that is classed as non-durable and is suitable for use in humid areas or exposure to occasional wetting. It can be used in an exterior application when fully covered or given a fully external decoration.
BB/BB Grade Explained - We stock several grades of Russian birch, primarily we carry the second highest grade which is BB/BB. The BB/BB grade means that both the face and the back veneers are single piece veneers with no splices. Both face and back veneers can have up to 6 small color-matched patches, some light mineral streaks or tight pin knots. We also carry the BB/CP grade. The BB/CP grade requires a single piece face and back. The “CP” back veneers are downgraded from the “BB” grade veneers, this allows for unlimited patches and sound knots, but this does not allow for open defects. Inner cores are solid birch single piece veneers.
