DUCT LINER BOARD (DLB)
DESCRIPTION
Duct Liner Board is a highly efficient, semi-rigid insulation composed of fine, stable and uniformly textured inorganic glass fibers bonded together by a non-water soluble and fire retardant thermosetting and heat resistant resin. It is free from coarse fibers and shot due to its Mineral composition.
APPLICATION
Duct Liner Board is intended for use in commercial, institutional, industrial and residential construction as thermal and acoustical insulation of heating air-conditioning and interior of dual temperature duct work, air handling equipment and plenums operating at air-velocities up to 30 m/s (6000 FPM) and temperatures up to 260°C (500°F).
Also used as an efficient sound absorption treatment of walls and ceilings, acoustic enclosures, generator rooms, studios, curtain walls, auditoriums, conference rooms, theaters and others.
