What kind of plywood is the lightest?
Among solid-veneer plywoods, paulownia is the lightest, at 260–310 kg/m³ — about half the weight of birch. If composite construction is allowed, honeycomb-core panels can drop effective density to 180–250 kg/m³, but they trade away screw-holding strength.
What is the lighter version of plywood?
Poplar plywood is the most common lightweight substitute for standard birch — about 30% lighter, similar workability, lower cost. For deeper weight savings, paulownia or honeycomb-core panels go further at higher cost.
What is stronger but lighter than plywood?
Honeycomb-core sandwich panels and aluminium honeycomb composites have higher stiffness-to-weight than solid-veneer plywood. They are not stronger in absolute terms — the face panel still does the work — but for resisting bending in a large flat surface, they outperform plywood per kilogram.
What is the lightest ply board?
Paulownia ply at roughly 12–14 kg per 3/4″ 4×8 sheet is the lightest solid-veneer option in standard plywood format. Honeycomb-core panels at 8–12 kg per equivalent sheet are lighter but are technically composite panels rather than plywood.
Is lightweight plywood as strong as standard plywood?
No. Density and strength track together for solid-veneer plywood. Poplar gives up about 20–25% of birch's MOR. Paulownia gives up about 50%. Honeycomb-core panels have high bending stiffness but low edge strength and poor screw-holding without solid inserts.
Where can I buy lightweight plywood?
Poplar plywood is stocked at most full-service lumber yards and many big-box retailers in the US, UK, and Canada. Paulownia, okoume marine, and honeycomb-core panels are specialty items — marine suppliers, RV-build outfitters, and direct-from-mill orders are the usual sources. Vinawood supplies poplar-faced multi-purpose plywood to importers in 19+ markets; contact a regional distributor for stock and pricing.
