JM Climate Pro attic insulation is engineered for effective resistance to heat transfer. It will not lose its R-value, even when temperatures are very cold. When applied to the recommended thickness and specifications, it improves energy efficiency and it’s effective for the life of your home.
The following are conclusions about JM Insulation's Winter Weather Performance by JM
Did you know?
Cellulose insulation manufactures keep referencing to an almost 30 year old study to claim fiberglass insulation loses its thermal protection ability in cold weather. That is not the case with modern fiberglass insulation, especially JM Climate Pro premium attic insulation.
In fact the North American Insulation Manufacturers' Association (NAIMA), a trade group representing fiberglass insulation makers, challenged these claims that a certain cellulose manufacture was advertising. NAIMA was successful in this challenge and the National Advertising Division ruled in favor of NAIMA and recommended the cellulose manufacture cease making these claims.
Johns Manville Climate Pro attic blow-in insulation is designed not to settle. Properly installed JM Climate Pro insulation maintains its thermal performance for the life of your home. This means No shrinking, No settling, No loss of thermal protection!
Did you know?
Cellulose manufacturers agree that their products settle over time. Most set the settling rate at about 20%. Therefore, if cellulose is mistakenly installed to its labeled settled thickness, it may lose about 20% of its R-value when it settles. That is not what you paid for!
Johns Manville Climate Pro attic blow-in insulation is noncorrosive: it does not accelerate corrosion of pipes, wiring or metal studs. If JM Climate Pro is exposed to moisture, it will not wick up and hold water, thus it resists any permanent loss of R-value. If fiber glass insulation becomes saturated as the result of flooding or other events not related to actual product use, it should be removed and replaced.

Cellulose is treated for flammability using acids that become acidic when wet. The following clip is taken from a website that is promoting cellulose:
"Wet insulation of any stripe is bad. But cellulose is hygroscopic. It’s able to soak and hold liquid water. Undetected leaks can wet cellulose causing it to sag within framing cavities. Water leaks can compress the blanket of fiber and in extreme cases, can create a void space, degrading its thermal value. Another concern is that chemicals used to protect cellulose from fire make it potentially corrosive in wet environments. Tests conducted by the Oak Ridge National Laboratory show chemical treatments used to treat cellulose can cause metal fasteners, plumbing pipes and electrical wires to corrode if left in contact with wet, treated cellulose insulation for extended periods of time."
Fiberglass insulation is made from sand and other inorganic materials which are melted and then spun into fiber glass. Fiberglass is naturally noncombustible and remains so for the life of the product. It requires no additional fire-retardant chemical treatments.
Unfaced fiberglass insulation also is recognized by building code groups as an acceptable fire stop in residential wood frame walls.

OUR INSULATION PASSES NORTH AMERICA’S TOUGHEST AIR QUALITY TEST.
The complete line of JM Formaldehyde-free™ building insulation products has been tested by an independent, nationally recognized laboratory to determine emissions of toxic volatile organic chemicals (VOCs) of concern, including formaldehyde.
No Formaldehyde, no added chemicals for fire resistance. Safe for you, safe for your family!
DID YOU KNOW?
Boric acid used in cellulose insulation may be more harmful than you think. Boric acid has been found to meet REACH criteria for classification as toxic for reproduction. In fact a popular brand of cellulose has this on their Safety Data Sheets:

JM Spider Plus and all other Johns Manville fiberglass products are free from harmful chemicals. Residential fiberglass insulation is also non carcinogenic . On June 10, 2011, the National Toxicology Program (NTP) removed from its list of “Reasonably Anticipated To Be Carcinogens” biosoluble glass wool fibers used for home and building insulation.
Throughout the years, NAIMA has asserted that “biosoluble” fiber, fiber that readily dissolves in the lungs, is safe to manufacture, install and use when the proper work processes are followed.
Johns Manville did testing and the findings confirmed that insulation glass fibers dissolve in the lungs relatively quickly, removing any potential for the chronic inflammation that could lead to ill effects on the lungs.
