Fiber Glass

Johns Manville fiber glass batts and rolls offer proven performance and energy savings at a great value compared to other insulation materials. And the benefits of our home insulation don’t stop there. More than a decade ago, JM was the first company to offer a complete line of certified Formaldehyde-free™ fiber glass home insulation. By removing the formaldehyde we are able to promote healthier and safer indoor air quality for our home insulation customers.

JM fiber glass batts and rolls come in a variety of facings and sizes, with R-values ranging from R-11 to R-38. The higher the R-value, the greater the insulating power, energy savings and comfort.  Be sure to check our project guide to find the recommended R-value for your project.
