What is R-value?

R-value is the measurement of an insulation's ability to prevent heat flow. The higher the R-value, the more insulating power it provides. ROXUL ComfortBatt delivers top performance for all thermal applications around the home. It is available in the following sizes:

  • 3½" thick batts with R-value ratings of R14 and R15 (US only) for use in 2 x 4 exterior wall applications.
  • 5½" thick batts with R-value ratings of R22 and R23 (US only) for insulating attics and 2 x 6 framed exterior walls.
  • 7¼" think batts with R-value rating of R28 and R30 (US only) for insulating attics and 2 x 8 framed exterior walls.


Equally important, the R-value of ROXUL insulation is not affected by water. ROXUL ComfortBatt™ does not store or transfer moisture, and it's completely resistant to mold, mildew, rot and bacterial growth. 

Where to Use ROXUL ComfortBatt

Energy savings begin with a properly insulated attic and exterior walls. But  there are other applications that can make a big difference in your home's comfort. Insulating the exposed concrete walls in your basement and heated crawl spaces are effective ways to improve the energy efficiency of your home. ROXUL insulation is easy to cut and install. Its unique stone wool composition, density, and friction-fit batts help you or your contractor prevent any gaps that can result in energy loss. 

A critical step when installing thermal insulation is the proper use of vapor barriers/retarders. Many building experts and professional contractors recommend polyethylene as the best choice. You should always consult your local building codes when you're doing the work yourself. More information on vapor barriers is available here.
