Why Choose Knauf EcoBatt?
Superior Thermal Control: The R-38 rating provides a dense thermal barrier, significantly reducing heating and cooling costs by preventing heat transfer through the attic.
ECOSE® Technology: A sustainable, plant-based binder that replaces phenol/formaldehyde. It is softer to the touch, generates less dust, and is easier to cut and install.
Built-in Vapor Barrier: The Kraft facing includes a stapling flange for easy installation and helps manage moisture levels within your walls and ceilings.
Acoustic Comfort: Beyond temperature control, the density of R-38 fiberglass helps dampen sound transmission between floors or from the outside.
Fire Resistant: Fiberglass is naturally non-combustible (note: Kraft facing is flammable and should be installed behind a thermal barrier like drywall).
Installation Note
This specific width (16") is ideal for standard wood joist spacing. Ensure the Kraft facing is installed toward the "warm in winter" side of the structure to properly manage moisture.
