AIREX®, BALTEK®, BANOVA® - Structural foam and balsa cores for an optimized performance in the marine market

Demands in boat and ship construction are particularly challenging as it involves diverse functional components. With AIREX®, BALTEK® and BANOVA®, 3A Composites AirexBaltekBanova offers composites for (nearly) all components: bulkheads and beams, transoms and wales, superstructures, hull bottoms, decks, to portholes and build-in closets.

Our offer of services and materials starts in the evaluation phase with the development of the most effective configuration of lightweight composites and the specification of the most cost-effective resources; it covers the complete process all the way up to production of the lightweight sandwich component - everything according to customer requirements.

Our structural materials are characterized by maximum impact and compression resistance, a high level of rigidity, low weight, easy formability, and absolute water tightness.

Our areas of application are as diverse as our materials:

  • Recreational boats
  • Racing boats
  • Luxury yachts
  • Cruise liners
  • Commercial and military ships
  • Greatest stability and rigidity
  • Maximum impact and compression resistance
  • Easy processing
  • Excellent aging properties and long-term stability
  • Aesthetics
  • Lower weight reduces fuel consumption and/or increased weight capacities
  • Hull bottoms
  • Wales
  • Decks
  • Superstructures
  • Interior fittings
  • Bulkheads and beams
  • Transoms
  • Portholes and covers




Winning a sailing regatta requires a lightweight and sturdy boat. AIREX® T92 SealX as core for the hull composite for the racing yacht "Fifty-Fifty" helps: 364 m² sail area at 1500 kg weight. And the course record already during the first long-distance regatta.
