InsulWeb High-Strength Insulation Support Fabric (8' x 300')

Take the guesswork out of wall-cavity insulation. InsulWeb is a professional-grade, non-woven polyester fabric specifically engineered for dry-blown cellulose and loose-fill fiberglass applications.

Its unique "breathable" design allows air to escape efficiently while trapping even the finest insulation particles, resulting in a tight, thermal-efficient pack that won't sag over time.

Key Features

Superior Durability: Engineered to withstand the pressure of high-volume blowing machines without tearing or stretching.

Folded for Convenience: The 8-foot width is folded down to save space in your truck and make it manageable for a single installer to roll out.

Translucent Finish: Easily locate studs and inspect the insulation pack through the fabric to ensure no gaps or voids.

Multi-Purpose Use: Ideal for residential new construction, retrofits, and commercial wall assemblies.
