Applications
Baltic Birch Plywood is an imported plywood
Highly decorative, exceptional strength and great screw holding power.
The front, back and inner plies are quality one-piece plies.
In spite of the odd 60 inch by 60 inch format, Russian Birch has been a
very high quality addition to the Imported Plywood market. Because of
its clarity and strength many manufacturers are using this material. The
Russian Birch uses more uniform plys in its construction than other
imported panels and because of this it has excellent machining
properties.
The dense construction and quality of veneer have made this a favorite
product of Cabinet Manufacturers throughout the country. The material
also has many aesthetic qualities it sands, paints and stains very
nicely.

The thinner stock is known best among crafters. It is used by scroller’s
for ornaments, model airplane builders, model railroaders for buildings,
doll house builders, model makers and as a base for parquetry work. Also
the latest users are those that have lasers.
Q: What is Baltic Birch?
Baltic Birch, aka ‘Russian Birch’, is a popular panel best known for its
light color, strength, multi-ply construction, and affordable cost.
Russian birch plywood is considered to be just a few steps behind
Finland birch in quality, because you will rarely find Russian birch
plywood with two perfectly clean faces. But it is available. Still,
Russian birch has layers of veneer that are void-free, which makes it
perfect for scroll saw cuts. Once you have cut your pieces, it’s easy to
cleanly finish the edges to produce a beautiful finished project.

Q: Why is Baltic Birch veneer better?
Baltic birch veneer is produced in the United States, BUT the highest
quality veneer for this type of tree is actually produced in Finland and
Russia. What sets the veneer from these countries apart is the
consistency of surface; Baltic birch veneer from Finland and Russia is
virtually free of gaps and voids. This disparity cannot be attributed to
quality milling; instead, it reflects the fact that the Baltic birch is
indigenous to the northern Baltic regions and is generally healthier in
that area. This means that the wood used to create the birch veneer in
these countries is less prone to wood bugs and other ailments that can
befall Baltic birch trees in more temperate climates.

Q: Why should I use Baltic Birch?
Using Baltic birch plywood in your projects is a great way to avoid
common problems like surface collapse, since this plywood is virtually
free of voids on the inner plies. This lack of voids gives Baltic birch
tremendous strength, and also presents a very attractive side profile
without the gaps and voids common in many other types of plywood. While
Baltic birch plywood may be a bit harder to find than other types of
plywood, it can be well worth the effort for many different projects. An
understanding of the grades and composition of this unique type of
plywood will show why Baltic birch should be considered among the finest
types of plywood.

Q: What sizes does it come
in?
The most common Baltic Birch sheet size is 60 inch by 60 inch. However,
there are 48 inch x 72 inch and 48 inch by 96 inch sheets becoming
available in the marketplace. I have 8 1/2 x 11, 12 x 12 & 12 x 13 3/4 in both 1/8
& 3/16. In 1/4 inch through 3/4 I have 12 x 12, 12 x 24, 24 x 24 & 24 x
48.

Q: What thicknesses do you carry?
There are a myriad of thicknesses for this product and vary with
suppliers. Currently I have the following thicknesses on hand for Baltic
Birch:
| Thickness |
*Thickness |
| (mm) |
(inches) |
| 3mm |
1/8” |
| 4mm |
3/16” |
| 6mm |
1/4” |
| 9mm |
3/8” |
| 12mm |
1/2" |
| 15mm |
5/8” |
| 18mm |
3/4” |
* Note – the Baltic Birch thicknesses in inches are approximate. For
example, the most common thickness for drawer sides is 12mm or 1/2”. A
true half inch = 12.7mm. Baltic birch has been around long enough that
the equivalency ratios stated above are considered the norm.

Q: What are these grades? They don’t look familiar.
There are two basic grades of imported plywood made from Baltic birch.
Finland birch plywood is considered the highest quality, because it will
have both faces entirely free of patches or plugs. You can also purchase
BB/BB grade low grade birch plywood that may have so-called "football"
shaped patches on both sides. They are different from the domestic
grades many of us see. Baltic Birch is manufactured in accordance with
the Russian export GOST 3916.1-96 standards. The list you see below is
simplified.B----Selected one-piece face, generally light and
even in color. Occasional small pin knots and some brown streaks may be
allowed, but generally no patches, voids or mineral streaks. Sanded
surface intended for natural finish. BB—One-piece face generally light
and even in color. Pin knots and mineral streaking or discoloration is
allowed with occasional sound tight knots permitted. Open knots and
defects in BB face veneers have been cut out and replaced with small
oval or round veneer “football” patches before gluing. The veneer
selected for the patches is of the same general color as the face
veneer. Sanded surface.
CP—One-piece face very close to grade BB. Rejected from BB for small
defects with more streaking. Occasional hairline splits of less than
.5mm are allowed. The oval or round patches may or may not be matched
for color with the base face veneer. There will normally be more patches
per face than the BB grade. Sanded surface.
C---Patches, open knots and veneer splits allowed. Not sanded.

Q: What grades do you carry?
I carry B/B also known as Double B (clear two sides, meaning no boat
patches) and B/BB also known as Triple B (clear one side, boat patches
on one side)
Back to Top
Q: If Baltic birch doesn’t come clear two sides
how can you sell clear two sided plywood?
On the lots that I sell I cut those sizes from larger pieces and sort
them myself. This way I can offer good two sides or B/BB grade.
Back to Top
Q: What type of glue do they use? Can this be used outside?
Baltic Birch comes in Type I and Type II glues. Type I is a phenolic,
exterior glue. This does not mean that an exterior glue is a substitute
for a true marine plywood. This simply means that the panel will perform
slightly better in outdoor applications. Type II glue is an interior
glue, and by far the most prevalent in today’s marketplace. The Baltic
birch I sell uses Type II glue - interior.

Q: You don’t have the size I need. Can I get a special size?
If you need a special size we will custom cut to order. Let us know the
size, thickness and number of pieces you need and will give you a quote
with S & H.

Q: What does Multi-ply construction mean?
Multi-ply construction means that the plywood is constructed with more
plies than a standard, domestic piece of plywood.

Applications –
In the US Baltic Birch made the most noise as a drawer side. The
multi-ply construction made for an attractive edge to route and sand.
The light color looked great as a drawer. And the price made this
product perfect for many.
Baltic Birch has been adopted as the product of choice for many of the
applications listed below:
Drawer sides
Table tops
Bed desk
Die cutting
Cabinets
Drawer bottoms
Skateboards
Furniture
Curio Cabinets
Book cases
Displays
Exhibits
Tole Painting
