Fiber Glass Batts & Blankets

Fiber Glass Insulation

  • R-values up to R-38
  • Cut to fit standard attic spaces and wall cavities

Our ongoing commitment to sustainability:

JM pioneered Formaldehyde-free fiber glass insulation over a decade ago. Now, its fiber glass building insulation is made with a rapidly renewable plant-based binder. Its field-tested, uniquely-engineered binder technology means less dust.

In addition:

  • JM Formaldehyde-free fiber glass home insulation contains 35% post-consumer recycled content in all batts and roll products*
  • Insulation saves twelve times the energy required to produce it**
  • Fiber glass is made from sand, a naturally renewable source
  • Insulation saves over 600 times more energy each year than all of the compact fluorescent lights (CFLs), Energy Star Appliances, and Energy Star windows combined***

*North American average. Recycled content will vary.
