Thermal and acoustical insulation products fabricated from lightweight, fire-resistant polyimide foam. Open-cell foam available as thermal and acoustical hullboard, pipe covering, and transmission-loss treatment. Closed-cell foam available for anti-sweat hull treatment.



  • Shipboard hulls, bulkheads, overheads, and ducts requiring thermal and/or acoustical treatment per DOD-I-24688.

  • Submarine hull and frame sections requiring sound transmission-loss treatments. TLT-DB is the U.S. Navy’s approved alternate to MIL-T-24708.



  • Weight reduction— Lightweight polyimide foam offers substantial weight savings.

  • Fewer mechanical fastening devices required.

  • Polyimide foam is inherently fire resistant, thus yielding longer burn-through times, low surface-burning characteristics, very low smoke developed, no significant toxic offgassing.

  • Full approval by U.S. Navy.

  • Factory-applied facings and jacketings include glass cloth, aluminized Mylar, Tuffskin, perforated glass cloth, and others.

  • Improved habitability— Increased resistance to abuse and water damage.

  • Shipboard chilled-water lines and systems up to 100°F. Vapor barrier jacketing or lagging is required per MIL-STD 769 and MIL-STD 635.
