Insulation Glass Wool Blanket Class A HVAC Range Hood Flexible Duct Interlayer Filling

This glass wool blanket is specially designed for flexible ducts in HVAC systems and range hood exhaust applications. Manufactured from high-quality glass through high-temperature melting, centrifugal spinning, and specialized thermosetting resin application, it is available in unfaced form for flexible duct interlayer filling.

The product serves as a thermal and acoustic insulation layer between double-layer flexible ducts, offering excellent thermal insulation to reduce heat or cooling loss while providing good acoustic absorption to minimize airflow noise. It is soft, lightweight, easy to install, and achieves Class A non-combustible rating for safe operation.
