Knauf EcoBatt R-13 is unfaced fiberglass batt insulation for 2x4 walls and other framing cavities. It is made from sand and over 50% recycled glass, bonded with the ECOSE binder instead of formaldehyde, and carries GREENGUARD Gold certification. R-13 is the standard value for 2x4 exterior walls, so it competes directly with other R-13 batts on indoor-air quality and handling rather than on thermal performance. It suits DIYers and contractors insulating stud walls, floors and ceilings who want a low-odor, formaldehyde-free batt.

Owners and installers generally describe EcoBatt as a low-odor fiberglass batt that is easier on the nose than older formaldehyde-bonded insulation. Complaints center on the usual fiberglass handling issues and on batts arriving compressed or short in the bag.
Knauf EcoBatt is an unfaced R-13 fiberglass insulation batt made with ECOSE Technology. It is a flexible glass mineral wool made from sand and over 50% recycled glass bottles.
The binder is naturally brown and made from corn, sand, and recycled glass, with no added dyes. The batts are soft to the touch, easy to cut, and less itchy.
Fiberglass insulation improves thermal performance and helps heating and cooling systems run more efficiently, which lowers energy use. The batts also control sound between floors and in interior walls, such as in bathrooms, kitchens, laundry rooms, family rooms, bedrooms, and theatre rooms.
