The Knauf Glasswool Blanket / Felt Insulation is a flexible fiberglass (glasswool) insulation material designed for thermal and acoustic insulation in building and HVAC applications. It is manufactured from fine glass fibers bonded with resin, providing excellent heat resistance, sound absorption, and fire safety performance.

Supplied in roll form (blanket or felt), this insulation is easy to handle and install on large surface areas and irregular shapes, making it ideal for continuous insulation coverage without gaps. It helps reduce heat transfer and energy loss, improving overall building energy efficiency and indoor comfort.

The material is non-combustible and offers reliable fire resistance, making it suitable for use in fire-rated assemblies and safety-critical environments. It also provides good acoustic performance, reducing noise transmission in walls, ceilings, and ducts.

Available in various thicknesses, densities, and facing options (such as aluminum foil or kraft paper), it can be installed using mechanical fixation, wire mesh, or adhesives depending on the application.

Suitable for roofs, ceilings, partitions, HVAC ducts, industrial insulation, and commercial buildings where thermal efficiency, acoustic control, and fire safety are required.
