Okoume and birch are two of the most widely used plywood types in the world, and they could hardly be more different. Okoume plywood, made from a light African hardwood, is famous for marine use, boat building, caravans and anywhere weight matters. Birch plywood, made from northern European hardwood, is heavy, stiff and hard-faced, prized for furniture, shopfitting, flooring, formwork and laser cutting. Comparing okoume vs birch plywood helps boat builders, joiners, furniture makers, vehicle converters and distributors choose the right panel for each job.
In this guide we compare the two on weight, stiffness and strength, surface quality, water resistance and marine use, screw holding, machining, supply and price, and look at where each one performs best. At Global Timber Trade Hub we supply okoume timber and plywood from Gabon and the Republic of Congo.
In short
- Okoume plywood is much lighter; birch plywood is heavier, stiffer and harder.
- Okoume is the classic marine and boat-building plywood.
- Birch gives a smooth, hard face and excellent screw holding.
- For weight-sensitive builds, okoume wins; for heavy-duty furniture and floors, birch.
- Both are available in marine and exterior grades with suitable glues.
- Birch supply has shifted since sanctions on Russian wood products in 2022.

Weight
This is the biggest difference. Okoume plywood is roughly 20–30% lighter than birch plywood of the same thickness. For a boat, a camper van, a caravan, an aircraft interior or a stage set, saving that much weight across many panels matters a great deal. Lighter panels are also easier to handle and install. For static uses such as furniture, shelving and floors, the extra weight of birch is rarely a problem, and its density brings other benefits.
Stiffness and strength
Birch plywood is stiffer and stronger than okoume plywood of the same thickness, partly because birch is denser and partly because birch plywood often has more, thinner plies. That makes birch the better choice for shelves, floors, workbenches, vehicle floors and structures where deflection matters. Okoume plywood is strong for its weight, which is why boat builders use it with epoxy and glass fibre to build light, strong hulls.
Surface and appearance
Birch plywood has a pale, smooth, hard face that takes clear finishes well and is popular for exposed-edge furniture and interiors, where the striped edges are part of the look. Okoume has a pinkish-brown face with a softer surface that dents more easily but takes paint, varnish and epoxy coatings very well. For boats, okoume’s face is often covered by paint or sheathed; for visible furniture, birch’s face and edges are usually preferred.
Water resistance and marine grades
Water resistance depends mainly on the glue and the quality of the veneers. Both okoume and birch are produced in exterior and marine grades with water- and boil-proof glues. Marine plywood made to standards such as BS 1088 uses high-quality veneers with limited core gaps. Okoume is the traditional marine plywood species and is widely available in BS 1088 grades. Birch marine plywood exists, but it is heavier. Neither wood is naturally very durable, so marine panels must be sealed and protected. See our okoume marine plywood guide.
Screw holding and machining
Birch’s density gives it excellent screw holding, which is why it is used for furniture carcasses, jigs and fittings. Okoume holds screws less firmly, so boat builders often use glue, epoxy fillets and through-bolts rather than relying on screws alone. Both machine well; birch gives crisp edges for CNC and laser cutting, while okoume is softer and quicker to cut but can fuzz with dull tools.
Supply and sanctions
Historically, a large share of the world’s birch plywood came from Russia. Since 2022, the EU, the UK, the United States and other countries have restricted or banned imports of Russian wood products, so birch plywood now comes mainly from Finland, the Baltic states and other suppliers, and prices have risen. Okoume grows mainly in Gabon and the Republic of Congo, and much okoume plywood is made in Gabon and in Europe from African veneers. For some buyers, okoume is now a useful alternative where weight or price matters.
Price
Prices for both vary with thickness, grade, glue and origin. Marine grades cost more than exterior or interior grades. As a rough guide, okoume plywood is often competitive with or below birch plywood of similar grade per sheet, especially since birch supply changed. Sawn okoume timber starts from about $520 per m³ FOB. See our okoume wood price guide.
Best uses for okoume plywood
- Boat hulls, decks and interiors.
- Caravans, camper vans and motorhomes.
- Stage sets, exhibitions and lightweight furniture.
- Painted joinery and panels where weight matters.
Best uses for birch plywood
- Furniture with exposed edges.
- Shelving, worktops and workbenches.
- Floors in vehicles and buildings.
- Shopfitting, CNC and laser cutting.
- Concrete formwork (film-faced).
A worked example for a camper van converter
Consider a company that converts vans into campers, fitting beds, kitchens, cupboards and wall panels. Every kilogram of furniture reduces the payload available for passengers, water and luggage, and heavy vans cost more to run. The company used to build everything in birch plywood, which looked great but added weight. It now uses lightweight okoume plywood for wall linings, ceiling panels, cupboard doors and carcasses, and keeps birch only for the floor, the bed frame slats and the worktop, where stiffness and screw holding matter most. By switching most of the cabinetry to okoume, the company saves a meaningful amount of weight on each conversion. The okoume panels are painted or covered with laminate, and edges are sealed and lipped with solid timber. Customers get a lighter van with more usable payload, and the company still uses birch where its strength is needed.
Okoume plywood in boat building
Boat builders choose okoume plywood for stitch-and-glue kayaks and dinghies, sailing boat interiors, decks and bulkheads. It bends well, glues reliably with epoxy and is light, which improves performance. Sheathed in epoxy and glass fibre, okoume hulls are strong and durable. Use marine-grade panels with sealed edges and protect the wood from water ingress. See our best wood for boat building guide.
Lead times and payment
Okoume plywood and timber are usually ready to load in 4–8 weeks, depending on grade and volume. For first orders, a letter of credit or a deposit with balance against copy documents protects both sides. See our letter of credit for timber guide.
Combining both in one project
Many projects use okoume and birch together. A boat might use okoume for the hull, deck and bulkheads to save weight, and birch for engine beds, cabin sole supports or heavily loaded fittings. A shop fit-out might use birch for exposed-edge counters and shelving, and okoume for back panels, ceilings and painted parts that do not need birch’s hardness. A caravan might use okoume for walls and furniture and birch for the floor. Combining them lets you put weight and cost only where they bring real benefits. When designing with both, remember that they move slightly differently with moisture and have different screw-holding strength, so detail joints and fixings accordingly, and seal all edges. Our best wood for shelving and best wood for cabinets guides cover other material choices for furniture.
Finishing plywood
Okoume takes paint, varnish and epoxy coatings very well, and a thin epoxy coat seals it effectively for marine use. Birch takes clear lacquers and oils well and shows its pale face and striped edges. Seal every edge of both, because edges absorb water much faster than faces.
Sustainability and legality
Okoume comes from natural forests in Gabon and the Republic of Congo, where it is one of the most important commercial species and is often harvested under managed concessions, some FSC certified. Birch comes from boreal forests in northern Europe. Since 2022, sanctions mean that birch plywood of Russian or Belarusian origin cannot legally be placed on the EU, UK or US markets, so buyers must check origin carefully. For okoume, ask for legal origin documents and certification where needed. EU buyers must meet the deforestation regulation for both. See our EUDR timber compliance guide.
Ordering okoume
When you send an enquiry, tell us whether you need sawn okoume or plywood, the grade, thicknesses, sheet sizes, glue type and quantity, and your destination port. We will confirm availability and quote FOB or CIF.
For first orders of marine panels, ask for the grade certificate and a sample sheet, so you can check core quality, glue lines and face veneer before committing to larger volumes.
Common mistakes
- Using interior-grade panels outdoors: check glue and grade.
- Relying on screws alone in okoume: use glue and bolts too.
- Using heavy birch where weight matters: okoume saves a lot.
- Not sealing edges: water enters through exposed plies.
Our honest advice
Choose okoume plywood when weight matters most: boats, vehicles, caravans and lightweight structures. Choose birch plywood when stiffness, a hard face and screw holding matter most: furniture, floors, shelving and shopfitting. Many workshops stock both and use each where it performs best.
