Comparisons · Synthetic vs Natural Board
WPC vs Plywood
WPC boards (sometimes sold under brand names like Multiwood) swap wood fibre for a PVC-and-wood-flour composite — fully waterproof, but with different strength and finish trade-offs than plywood.
| Aspect | Plywood | WPC Board |
|---|---|---|
| Core material | Natural wood veneers | PVC plus wood/mineral flour composite |
| Water resistance | Good in BWR/BWP grade, not fully waterproof | Fully waterproof, unaffected by standing water |
| Weight | Lighter | Heavier for the same thickness |
| Screw-holding | Strong | Moderate, can strip more easily under repeated use |
| Termite/borer resistance | Needs treatment | Naturally immune — no organic wood fibre for pests |
| Best use | General furniture, structural panels | Bathroom vanities, wash areas, high-moisture modular units |
Full Waterproofing Has Trade-Offs
Immune to Standing Water
Unlike even BWP plywood, WPC board is unaffected by direct, sustained water contact — ideal for bathroom vanities and wash areas.
No Termite Risk
With no organic wood fibre in the core, WPC board has nothing for termites or borers to feed on.
Heavier & Less Rigid Over Spans
WPC board is denser and heavier than plywood, and can flex more than plywood over long unsupported spans.
Screw-Holding Needs Care
WPC holds screws less tightly than plywood under repeated opening and closing, so hinge points benefit from careful fixing technique.
A Note on the "Multiwood" Name
Multiwood is one well-known brand name in this WPC/PVC foam board category, and the terms are often used interchangeably in the market — but as with any material, it's worth confirming the specific board's density and grade rather than assuming by brand name alone. See our marine plywood guide for the natural-wood alternative when full waterproofing isn't required, and our Action Tesa MDF range for our Moist Master moisture-resistant board option.
Thickness-wise rates for the boards themselves: WPC foam board in 8mm, 12mm and 18mm (plus 24mm and 30mm door grades), and PVC foam board in 5mm, 8mm, 12mm and 18mm.
Frequently Asked Questions
Is Multiwood the same as WPC board?
Multiwood is a well-known brand name in the WPC (wood-plastic composite) / PVC foam board category, so the terms are often used interchangeably in the market, though it's worth confirming the specific product's density and grade.
Is WPC board better than plywood for bathrooms?
For fully wet areas like bathroom vanities and wash counters, yes — WPC's complete water immunity outperforms even BWP-grade plywood, which resists moisture but isn't fully waterproof.
Is WPC board heavier than plywood?
Yes, generally — WPC's PVC and mineral-flour composite core is denser than plywood's layered wood veneers, so a WPC sheet of the same thickness weighs more.
Does WPC board hold screws as well as plywood?
Not quite as well — plywood's cross-laminated wood grain generally grips screws more securely than WPC's composite core, which matters for hinges opened and closed frequently.
Can WPC board be used for general furniture, not just wet areas?
Yes, it can, though its main advantage — full waterproofing — is most valuable in bathrooms, wash areas and other consistently wet environments; plywood remains a lighter, often more cost-effective choice for general furniture.
