Fire-retardant Okoume plywood in a 4 mm thickness is a thin, lightweight multi-ply panel for interior fit-outs. Each veneer ply is impregnated with fire retardants, so when exposed to fire, the material smoulders slowly with minimal smoke emission. Sheets measuring 2500 x 1220 mm (3.05 m²) are used to manufacture suspended ceilings, lightweight wall panels, cabinet backs, and lining for lift cars or ship cabins. The thin sheet is easy to cut, sand, paint, and overlay with sliced veneer. Available from a single sheet or in bulk. You can collect your order in person from our warehouse in Kyiv (7-D Zdolbunivska St). Plywood dispatch via freight carriers across Ukraine is available.
Features of Fire-Retardant Okoume Plywood: Why the Material Resists Combustion
Fire-retardant Okoume plywood is a multi-ply wood-based panel that does not ignite when exposed to fire, but smoulders slowly with minimal smoke emission. The panel consists of an odd number of veneer plies made from tropical Okoume (Gaboon) timber from Central Africa.
This is not standard plywood merely coated with a fire-retardant lacquer on the outside. The material’s resistance to ignition is ensured by three technological factors:
- Impregnation of each veneer ply. The timber is treated with fire retardants before the veneer sheets are bonded into a panel. The material is protected throughout its full thickness, so it does not lose its properties after cutting.
- Smouldering instead of open flaming. Under high temperatures, the impregnation blocks oxygen from reaching the wood fibres. The absence of open flames and low smoke emission (Euroclass B-s1, d0) provide extra time for safe evacuation.
- Heat-resistant bonding. The veneer plies are cross-banded and bonded with a special heat-resistant adhesive. The glue line does not break down under heat or moisture, preventing the panel from delaminating in extreme conditions.
The combination of deep fire-retardant treatment and the close-grained structure of African veneer makes the panel a reliable solution for projects with strict fire safety requirements. The material simultaneously protects premises against the spread of fire and preserves the aesthetics of exotic timber.
Advantages of Fire-Retardant Plywood for Manufacturing
For furniture factories, joinery workshops, and contractors, fire-retardant Okoume plywood is convenient because it requires no special tooling. It is just as easy to machine as standard wood-based panels.
In manufacturing, flame-retardant Okoume plywood offers the following advantages:
- Low weight. The dry density of solid Okoume timber is 430–500 kg/m³, making the sheets 25–30% lighter than birch equivalents. This reduces the load on furniture hardware, fixings, and load-bearing ceiling or wall structures.
- Dimensional stability. The cross-banded structure of the panel relieves internal stress, so the sheet retains its flatness and shape and does not cup or twist over time.
- Ease of machining. The uniform timber without internal voids cuts cleanly on panel saws and routs on CNC machines without chipping. Important tip: after sawing or routing, exposed edges should be treated with a fire-retardant primer to maintain the integrity of the protective barrier.
- Mahogany aesthetics. The rotary-cut surface of Okoume is smooth with a natural lustre. The colour palette consists of pale pink and light brown shades. After sanding and varnishing, the surface visually resembles mahogany, and it is also easy to paint and overlay with decorative veneer.
Thanks to these characteristics, fabricators can quickly put commercial orders into production. You get a lightweight material that cuts predictably and passes fire safety inspections.

Grades of Fire-Retardant Okoume Plywood
Grading is based on the condition of the outer (face and reverse) veneer plies in accordance with the current standard DSTU EN 635-2 (where the letter designations B, BB, and CP correspond to European appearance classes I, II, and III).
Because Okoume timber has a straight or slightly interlocked grain and a uniform texture, the sheets are free from coarse defects. Depending on the permissible allowances per 1 m², 4 combined grades are distinguished:
- B/BB (I/II) — suitable for clear varnishing or wood staining. The face veneer is clean, with a uniform pinkish-brown tone and free from repair patches. Only pin knots or sound intergrown knots up to 3–5 mm (up to 2–3 per 1 m²) and occasional closed end splits up to 100 mm at the edges are permitted.
- BB/BB (Class II/II) — suitable for staining, painting, or double-sided (two-side) veneering. Both sides are sanded and of identical quality. Sound knots up to 10–15 mm (up to 3–5 per 1 m²), neat colour-matched veneer repairs (up to 2–3 patches), closed splits up to 200 mm, and natural colour variations covering up to 10–15% of the surface area are permitted.
- BB/CP (Class II/III) — designed for single-sided components and panelling (cladding). The face surface is suitable for painting or veneering. The concealed reverse side (CP) permits intergrown knots up to 20–25 mm, an unlimited number of repair patches, filled splits up to 2 mm wide, and contrasting discolouration.
- CP/CP (Class III/III) — a cost-effective substrate for opaque overlays. Both sides contain knots, repair plugs (patches), and filled hairline splits that do not affect the panel’s geometry. It is an optimal choice for structural carcasses, subflooring, or laminating.
Please note: the price per sheet of plywood depends on the thickness and the selected surface grade. However, the bonding quality and fire-retardant performance remain equally high across all options: from decorative B/BB to utility CP/CP grade.
Where Fire-Retardant Okoume Plywood Is Used
Where a client wants timber in a commercial interior, but fire regulations prohibit standard untreated sawn timber, fire-retardant panels are used. Low-flammability plywood combines wear resistance, low weight, and compliance with fire safety standards.
Public Spaces and HoReCa
The panels are used to manufacture wall and ceiling panelling, reception desks, and furniture for hotels, restaurants, shopping centres, cinemas, bowling alleys, offices, schools, and airports. Such cladding restricts the spread of fire and improves indoor acoustic insulation and the microclimate.
Transport and Shipbuilding
The material is in high demand for the interior fit-out of passenger rail carriages, underground trains, and lift cars. Thanks to the moisture resistance of Okoume, the sheets are used to line cabins and corridors on sea-going and river vessels.
Protective Screens and Technical Areas
In industrial and commercial buildings, flame-retardant plywood is used to install zoning partitions and heat shields. The sheets are also used to line ventilation shafts, server rooms, and electrical switchrooms.
Subflooring and Podiums (Stage Platforms)
Thick panels (12–20 mm) are laid as a flat, strong substrate under finished floor coverings or used to build stage structures. Using fire-retardant Okoume plywood helps bring design projects to life without breaching building regulations. The structures withstand heavy use in high-traffic areas and last for decades.
