The AFICO Glasswool Duct Liner Rolls are high-performance fiberglass (glasswool) insulation rolls designed for internal lining of HVAC duct systems and air handling units (AHUs). They are manufactured from inorganic glass fibers bonded with a thermosetting, fire-retardant resin, ensuring excellent thermal insulation, acoustic absorption, and durability.

These duct liner rolls are engineered to reduce airborne noise and vibration within ductwork, improving overall indoor acoustic comfort. Their fibrous structure effectively absorbs sound energy, minimizing noise transmission through air distribution systems.

They also provide thermal insulation, helping to maintain air temperature within ducts and improve HVAC system efficiency, while reducing energy loss.

The material is designed for internal application inside ducts, with a smooth and stable surface that ensures proper adhesion and long-term performance. It offers fire-resistant properties due to its non-combustible glass fiber composition, contributing to enhanced system safety.
