Knauf's cost-effective thermal and acoustical batts and blankets are made from highly resilient, inorganic glass fibers bonded by a thermosetting resin.

The products are available unfaced or with kraft, foil, or flame-rated FSK-25 (Foil-Scrim-Kraft) foil facings.

Knauf duct insulation is designed for commercial and residential air handling installations for cooling, heating, or dual-temperature service where good temperature control, noise absorption, and abuse resistance are required.

Available as board, liner, wrap and rigid plenum liner.
