Owens Corning R-13 EcoTouch Insulation Roll vs Knauf EcoRoll R-13 Fiberglass Insulation Roll

Both are R-13 kraft-faced fiberglass rolls for 2x4 walls, so thermal performance is a wash. The Owens Corning roll is the easier homeowner pick: it is formaldehyde-free, GREENGUARD certified and widely described by owners as less itchy and faster to handle. The Knauf EcoRoll is a solid, LEED-eligible alternative that pros often choose for its clean kraft facing and consistent roll size. Pick Owens Corning for a first DIY job or a sensitive household; pick Knauf if you want a straightforward faced roll and your installer already trusts the brand.

• Choose the Owens Corning EcoTouch if you want a formaldehyde-free, GREENGUARD-certified roll that homeowners report is easier on the skin and simpler to cut and fit.
• Choose the Knauf EcoRoll if you want a standard kraft-faced R-13 mini roll that is LEED eligible and favored by contractors for clean facing and predictable sizing.
