Titus, Leaders in Air Management products, have recently introduced a IAQ liner for their VAV boxes. It has equal acoustic properties to fibreglass but unlike man-made fibreglass, the new liner is constructed of natural cotton fibers which do not contain harmful irritants making it safe and easier to handle.

Titus' EnviroLoc liner is an environmentally friendly, thermally bonded; high density, acoustic/thermal IAQ liner insulation designed for HVAC systems.

The EnviroLoc liner is made from high quality, natural cotton. The fibers contain inherent qualities that provide superb sound absorption and consistent thermal performance. The liner, Lydall’s LyShield™ IAQ (indoor air quality) product contains no chemical irritants and requires no warning labels.
