PLY ONLINE Raw Birch Plywood
Raw Birch Plywood is Birch Plywood harvested in the northern regions of Europe. Due to frosts, this plywood has very light natural colour.
Applications
Exterior and interior, architectural design, laser cutting, exterior and interior furniture, cabinets, joinery, flooring, wall panelling, soffit & interior ceilings, caravan and campervan walls, decorative and structural applications, staircase, partitions, refrigeration truck bodies, scaffolding planks, space dividers, DIV and hobby projects.
Advantages
- Excellent strength-to-weight ratio
- Durable and heavy-duty
- Good machining properties
- Low volatile organic compounds (VOC), including formaldehyde emissions
- Esthetic and visually attractive
- Sustainable product

Formaldehyde emission
Raw Plywood formaldehyde emission level is significantly below EN 13986 Class El and it is certified as complying to EPA TSCA Title VI and CARB Phase 2. It is also compliant with the requirements of the new REACH Formaldehyde Restriction Regulation EU 2023/1464, Finnish Emission Classification of Building Materials (Ml), French voe Emissions
Raw Birch Plywood can be processed in many different ways, including film overlaying or special composite materials, lacquering, oiling, cut-to size, CNC, drilling, milling, jointing, edge machining, assembling in sets, scarf jointing.
Gluing classes
Raw (uncoated) plywood is glued with weather and boil-proof phenol formaldehyde or lignin phenol formaldehyde resin adhesive according to EN 314/Class 3 Exterior. Bonding with moisture resistant melamine- ureaformaldehyde resin according to EN 314 / Class 1 and BS 1203 / H1 possible
Cut-to-Size
Grades
Raw Birch Plywood is sanded on both faces, forming a smooth and durable surface, which is suitable for a variety of finishes.
- B (I) for good quality staining and lacquering.
- BB (II) for finishing and coating with transparent and non transparent thicker overlays and films, veneering and applications where a solid face is required. CP (111) plywood is grade without open defects (repaired with filler), for overlaying with non-transparent finishing material.
- C (IV) for use where surface appearance is not important, reverse grade. Surface appearance classification fulfils the requirements of EN 635.
Construction And Storage
Construction
Raw Birch Plywood is made of 1.45 mm thick cross bonded birch veneers. Face veneers are available in long and cross grain. For customer-specific requirements, specially designed oriented veneer constructions can be used to improve the bending strength and stiffness properties.
Storage
- Plywood must be stored in a well ventilated, weather protected area with the panels stacked both horizontally and levelled.
