MarinePlywood
Structural multi-layer wood panel bonded with high-performance phenolic resins. The Marine grade uses durable-species veneers and is free from internal voids (no core voids), guaranteeing absolute resistance to humidity, thermal shocks and delamination in extreme environments.
The 90-degree cross-banding. Each veneer physically blocks the natural swelling of the adjacent sheet. The absence of internal voids prevents water from penetrating and stagnating inside the panel.
Not all plywood is equal. Marine Plywood represents the quality apex of laminated wood panels. Originally designed for boat hull construction, it has become the material of choice for external architecture exposed to severe climates and for furniture in humidity-saturated environments.
The secret of marine plywood lies in strict production standards. Unlike packaging plywood where core layers may contain fallen knots and hidden cracks, marine grade demands zero tolerance on internal voids. A void allows moisture to penetrate, condense and trigger internal rot. Hard tropical timbers such as Okoume (light and elastic) or Sapele Mahogany are used.
It is the glue, not the wood, that fails with water. Marine Plywood uses exclusively Class 3 Phenol-Formaldehyde thermosetting resins. The acronym WBP (Water Boiled Proof) means the adhesive withstands prolonged boiling cycles (72 hours) without delamination, guaranteeing the panel will never peel even when constantly wet or salt-water immersed.

Physical properties
Usage environment
EDGES: despite resistant glue and wood, cut panel edges remain vulnerable as they expose end-grain fibres that absorb water by capillary action. Always seal cut edges with two-component polyurethane or epoxy resin. Do NOT confuse Exterior WBP with Marine Grade BS 1088: the former may contain internal voids.
Documented applications
TAV. DBoat Building
Primary structural use: internal bulkheads, floors and hulls for wooden boats with epoxy.
External Cladding (Facades)
Okoume panels as external skin in ventilated facade systems, protected with UV varnishes and impregnants.
Wet Environments (Bathrooms/Kitchens)
Kitchen countertops, bathroom furniture and structural supports where humidity would destroy MDF.
Concrete Formwork
High rigidity and waterproof glue allow repeated use as smooth formwork for reinforced concrete.
Delamination Resistance (Immersion and extreme humidity)
TAV. EThe vast majority of commercial furniture uses particle board or MDF for cost reasons. For structural applications subject to driving rain or continuous wetting/drying cycles, marine plywood remains the unsurpassed technology.
