Our take on the Knauf Ecobatt R-13 Kraft Faced Fiberglass Insulation Batts

Knauf EcoBatt R-13 is a kraft-faced fiberglass batt for 2x4 walls and ceilings, bonded with ECOSE Technology instead of the usual phenol-formaldehyde binder. It is formaldehyde-free and Greenguard Gold certified, and it carries a minimum of 50% post-consumer recycled glass content. The soft, less-itchy feel and easy cutting make it friendlier to handle than older fiberglass batts, and the kraft facing adds a vapor retarder plus some sound damping for interior walls and floors. It is a standard R-13 cavity fill, so it competes with other faced fiberglass on handling and indoor-air credentials rather than on R-value.

Pros
  • ECOSE binder is formaldehyde-free and Greenguard Gold certified
  • At least 50% post-consumer recycled glass content
  • Softer and less itchy to handle than conventional batts
  • Cuts easily with a utility knife for odd cavities
  • Kraft facing acts as a vapor retarder and adds sound damping
  • Standard R-13 thickness fits common 2x4 framing
Cons
  • Faced batts need careful stapling and sealing to work as a vapor retarder
  • Fiberglass still requires gloves, eye protection and a mask
  • R-13 alone is below code levels for many cold-climate walls
  • Compressing the batt lowers its effective R-value

What reviewers say

Owners and installers describe EcoBatt as noticeably softer and less irritating than older pink fiberglass, with less dust and odor. They rate the recycled content and formaldehyde-free binder highly. Complaints center on the kraft facing tearing or needing extra stapling, and on the usual protective gear still being necessary.

Questions and answers

What does R-13 mean for my walls?
R-13 is the standard cavity fill for 2x4 exterior walls and is also used in ceilings and interior partitions. It meets code in milder climates but falls short of the higher R-values required in cold zones.
Is this insulation safe for indoor air?
The ECOSE binder is formaldehyde-free and the product is Greenguard Gold certified for low emissions. Fiberglass still irritates skin and lungs, so wear gloves, goggles and a mask while installing.
Can I use it on interior walls for sound?
Yes. The batts damp sound between rooms and floors, which suits bedrooms, bathrooms, laundry rooms and home theaters.
Do I need a separate vapor barrier?
The kraft facing acts as a vapor retarder when stapled with flanges to the studs and seams are sealed. In very cold climates, check local rules on facing placement before installing.
How does it compare with unfaced batts?
Faced batts add a vapor retarder and a little sound control, while unfaced batts are simpler where a separate membrane is used. EcoBatt's edge is its softer, formaldehyde-free binder.
What is in the package?
The package contains kraft-faced fiberglass batts in the size you select, with stapling flanges along the edges. Coverage depends on the batt size chosen for your cavities.
