Exterior Birch Plywood

WBP plywood for furniture and joinery

WBP (Weather and Boil Proof) plywood is a multi-layered exterior-grade panel made of rotary-cut veneer, the layers of which are bonded with a phenol-formaldehyde resin. The adhesive provides mechanical strength and resistance to delamination under the influence of moisture. The material is designed for use in conditions of fluctuating microclimates, increased mechanical loads, and direct contact with high-humidity environments.

We maintain a stock of panels of various thicknesses at our warehouse to meet the needs of joinery workshops, furniture factories, and construction contractors. To fulfil the client’s manufacturing tasks within a single order, we provide a comprehensive service.

1. We offer waterproof plywood, calibrated and sanded on both sides (S2S), in thicknesses from 4 mm to 21 mm.
2. We perform rough cross-cutting and precision cut-to-size services to order, as well as edge banding, cutting map generation (nesting), assembling veneer layons, and veneering with fine natural wood veneer.
3. We ensure the prompt dispatch of products from our warehouse in Kyiv after the order is fully paid. Warehouse pick-up and delivery across Ukraine via freight transport companies are available.

The minimum order is 1 panel (sheet). We also provide wholesale supplies. We have been operating in the Ukrainian market since 1996.

Specifications of WBP plywood: adhesive stability, benefits for manufacturing

The main technical difference of WBP panels lies in the chemical nature of the binder: a phenol-formaldehyde resin adhesive is used during manufacturing. Under high temperature and pressure in hydraulic presses, the glue line undergoes an irreversible polymerisation process, forming a synthetic bond that does not dissolve in water. Thanks to the cross-banded grain structure in adjacent veneer layers, the material gains increased resistance to cracking, impact loads, and dimensional deformation during temperature fluctuations.

It is important to correctly understand the specifics of the term «waterproof plywood».

The phenolic adhesive ensures the structure’s resistance to delamination under the influence of humid air, condensation, brief precipitation, or seasonal humidity fluctuations. At the same time, the panel’s core consists of natural wood, which inherently remains hygroscopic. WBP plywood is not intended for continuous immersion in water or constant aquatic exposure. Provided it is correctly finished with varnishes, oils, or edge sealants, the material demonstrates long-lasting stability even in demanding environments.

For a joinery or furniture enterprise, choosing high-quality WBP plywood directly affects production costs and the efficiency of manufacturing processes:

• a dense, void-free core guarantees a clean cut on CNC routers and the prevention of face veneer tear-out;
• thanks to the high wood density and the structural strength of the glue line, screws, confirmat screws, and furniture connectors are anchored in the face and edge much more securely than in traditional particleboard or MDF;
• high bending strength indicators allow for the use of thinner panels to create lightweight yet structurally rigid assemblies;
• low internal moisture content and careful surface sanding ensure uniform glue adhesion during subsequent wood veneering or painting.

The use of high-quality WBP plywood significantly minimises manufacturing defects and protects the manufacturer from customer complaints related to the swelling or warping of finished products.

Specifications of waterproof WBP plywood

To ensure joinery workshops and manufacturing facilities can receive materials quickly, we maintain a consistent stocking programme. The inventory includes products with the following specifications:

• Sizes: 1250 × 2500 mm (cross-grain panel) and 2500 × 1250 mm (long-grain panel).
• Wood species: birch/alder.
• Thickness: 4 mm, 6 mm, 9 mm, 12 mm, 15 mm, 18 mm, 21 mm.
• Surface finish: S2S (sanded two sides).

Correctly selected panel dimensions allow you to optimise material yield and minimise offcuts, while a calibrated, consistent thickness across the entire panel area significantly speeds up the hardware installation and assembly process.

Grades of waterproof WBP plywood

Plywood grade marking is indicated with a slash (for example, B/BB or CP/C) and determines the veneer quality on the face and back sides of the panel. Since the phenolic adhesive system provides equally high water resistance and structural strength across all panels, the grade exclusively dictates visual appearance: the presence or absence of knots, veneer splits, veneer plugs (patches), and natural wood tone variations.

For a manufacturer, properly selecting the grade is an effective tool for cost control, as it avoids overpaying for a premium face veneer where the part will ultimately be concealed or painted.

Warehouse stocks of B/BB, BB/BB, BB/CP, CP/CP, and CP/C plywood grades constantly fluctuate, so we highly recommend checking the current availability of your required material directly with a sales representative.

Where is WBP plywood used?

Unlike MDF or particleboard (chipboard) panels, waterproof WBP plywood withstands periodic temperature and humidity fluctuations without losing its structural integrity and provides excellent fastener holding power. Our clients typically use this material for projects where ensuring long-term structural durability is critical:

• furniture for high-humidity environments (wet rooms, kitchens, and bathrooms). Plywood with increased moisture resistance is used to manufacture washbasin vanity units, kitchen cabinetry, interior partitions, and other products for projects where there is a risk of condensation or brief water splashes;
• outdoor furniture and garden architecture. Popular uses of plywood panels include manufacturing benches, tables, chairs, gazebo frame cladding, decking areas, and open pavilions (provided protective exterior oils or varnishes are applied);
• the transport sector and trailer decking. The panel material is used to install flooring in light trailers and commercial van bodies. Plywood is also utilised to create cargo bay linings subjected to regular mechanical loads;
• interior partitions and wall panels. The panels are used to construct false walls and structural podiums for space zoning in commercial and residential premises. Furthermore, these panels serve as an excellent stable substrate for veneered architectural wall panels.

Proper use of WBP plywood guarantees exceptional dimensional stability and a long service life for the finished product.

What is the difference between waterproof WBP plywood and moisture-resistant MR plywood?

MR plywood is bonded with a urea-formaldehyde adhesive system, features moderate moisture resistance, and is intended exclusively for dry interior environments. WBP plywood is manufactured using phenol-formaldehyde resins, which polymerise into water-insoluble compounds. This structural material easily withstands increased air humidity, cyclical temperature fluctuations, and exterior applications under cover (canopies).
