Exterior birch

Piano Plywood Ltd are birch specialists and carry some of the largest and most varied stocks in the country.

 

Birch plywood grades and properties:


B – 
Solid veneers with no open defects or plug repairs. Suitable for high quality paint/stain or lacquer finish where the end product is open to display.


BB – 
Mainly solid face veneers with some small repaired veneer splits and pin knots. Larger open knots are repaired using wooden plugs. Some solid light and dark knots are admissible. Suitable for applications where a solid surface is needed but the visual aspects are not so critical.


CP – 
Generally as BB but with possibly more repairs, open defects and discolouration. This grade can also arise from the downgrade of higher quality grades. Suitable for applications where a strong core is needed but the accepted face quality can be more varied.

 

C – Usually un-sanded and allows a larger range of open defects. Suitable for applications where a strong solid core is needed but face quality does not matter.
