Benefits of Formaldehyde-free
Quite simply, it's the smart thing to do for the environment and our customers.
EasyFitComfortTherm
Better for the Environment
JM Formaldehyde-free insulation uses an innovative new acrylic binder that eliminates binder-related formaldehyde emissions during manufacturing, and after installation will not off-gas formaldehyde inside your home. And our insulation contains 20% post-consumer recycled glass.
 
Better Energy and Sound Efficiency
JM Formaldehyde-free insulation provides the same high-quality thermal and acoustical properties as conventional JM fiberglass. As a result, the beneficial effects of our formaldehyde-free insulation are also felt in the home, conserving enough energy annually to fuel North America's electric consumption for an entire month.
 
Better Moisture Control
 JM Formaldehyde-free insulation is naturally mold and mildew resistant, and our new MR-Faced product has a built-in Smart vapor retarder for further protection in high humidity areas.

Custom Homes Deserve Custom Insulation

Spider improves energy efficiency in the homes you build

No Gaps … No Voids … No Red Tags. Building codes are getting tougher across the country. For example, Title 24 is a new measure in California to verify the quality of insulation installations in low-rise residential buildings. A compliance credit can be achieved if the building also has an inspection by a qualified HERS rater.

JM’s Spider™ Custom Insulation System meets new codes standards across the country. Spider is formaldehyde-free fiber glass that sprays in almost dry, completely filling gaps and voids around electrical fixtures, pipes and other obstructions to give you superior insulation coverage. Plus, unlike cellulose, Spider will not settle or shrink, and it’s inorganic and naturally mold-resistant.

As you know, higher R-values mean greater energy savings. Spider achieves R-values up to R-15 in 2x4 walls and R-23 in 2x6 walls, so it meets or exceeds Title 24 requirements. In fact, since it’s designed for walls, Spider can achieve an R-value of 4.2 per inch of thickness – much more than the maximum 3.7 per inch R-value that wall-spray cellulose and open-cell foam products provide. Your homeowners will also appreciate the savings they’ll enjoy heating and cooling their home. Studies indicate that over 80 percent of homeowners want energy-efficient homes that include insulation above code requirements,* and are willing to pay for it.
