Product description

EcoBuild Clean Liner (ECL) Ultra is a range of Clean Liner products used in HVAC duct to offer superior acoustic comfort. It is produced by bounding together glass wool with green binder material.

EcoBuild Clean Liner (ECL) Ultra is faced with a black, strong, durable, dimensionally stable woven glass fabric. It is especially designed to provide improved IAQ and exceptional sound absorption to acoustically sensitive environments and/or equipments such as air-conditioning equipment, auditoriums, theatres, studios, acoustical building assemblies, curtain walls.
