Meet Knauf EcoRoll R-11 Kraft Faced Fiberglass Insulation Roll—an eco-friendly insulation solution that blends solid performance with easy installation. Designed for between-floor and interior-wall applications, it keeps your spaces comfortable while you mock up your dream remodel (or just finally stop blasting the heater at full power).

Key Features & Design

• Eco-friendly materials and ECOSE technology: Glass mineral wool insulation manufactured from abundant natural resources and at least 60% post-consumer recycled material bonded with ECOSE technology.
• Kraft-faced for a clean, ready-to-install option: Kraft facing adds a vapor barrier and simplifies handling during installation.
• Naturally brown binder: Naturally brown, eco-friendly binder made from corn, sand, and recycled glass (no added dyes).
• Comfortable to work with: Soft to touch, easy to cut, and less itchy—because insulation should keep the temp in check, not your patience.
