Navy board facing material (Style 3732 with 261 finish, patent #4,778,544) Low
Toxic Navy Board Facing is used extensively in the interior of ships to cover
bulkheads and passageways. Broad width fabric and narrow tape is woven with 100%
fiber glass to ensure flame retardancy, insulation protection, and durability.
The hullboard fabric, when perforated, allows the thick backing material to absorb
noise.
