Reasons Why Birch is a Preferred Plywood


Superior Screw Holding

Because the core layers of birch are actually veneers of birch and form a void-free core, screws bite and hold with 100% of their threads. Conversely, traditional veneer core plywood has voids and is also made up of softer materials so screws don’t get a chance to clench the best they can. You also might find sheet goods made with MDF (medium-density fiberboard) core, and though it’s 100% solid, MDF is soft and just doesn’t have the screw-holding power of Baltic birch.

 

Better Joinery

Because the core is free of voids, your joinery also won’t suffer from glue starvation—they’ll get 100% glue coverage. Anything you build out of birch should last a good, long time.

 

Strength and Stability

Birch is not immune, it’s still a wood product. However, birch has the odds stacked in its favor much better than other plywood, chiefly in 1/2″ and 3/4″ thickness. The cross-banded layers of 1.5 mm thick birch veneer makes the sheets balanced, which promises a flatter product. However the thinner sheets, like 1/8″ and 1/4″, simply will not remain flat in large pieces—and this is no surprise. That’s usually not a problem though because these are usually used in applications like drawer bottoms and cabinet backs where they’re cut down to smaller sizes. It should be obvious that the thicker sheets are more stable because they have more plies. 3/4″ Baltic birch in particular won’t change much in width or length, that’s why it’s great for jigs and fixtures that need to maintain accuracy over the years.

 

Good Appearance

One of the fortunate benefits to Birch, too, is that you can leave the edges exposed if you like the look. Because the core is free of voids and all birch, the exposed edges sometimes have an appearance that works for the project, and this saves you time and material—no need to spend time and effort on applying edge tape or solid edge banding unless you want to. To keep the uniform, light color instead, simply finish Baltic birch with a basic clear top coat of lacquer or polyurethane.

 

Reasonable Quality

With close inspection of Birch, you should notice that the face and back veneers are remarkably thicker than the veneers you’ll see on traditional cabinet-grade plywood. Sadly, it’s well-known that cabinet grade plywood veneer faces are dismally thin, which makes them easy to damage and easy to sand through. But not so with Baltic birch. Outer veneers are nice and thick.  As for the appearance, there are several grades of Baltic birch available, but we most often carry the second highest grade which is BB/BB.  BB/BB means both the face and the back veneers are single piece veneers with no splices.
