Johns Manville (JM), a
Berkshire Hathaway company and global building products manufacturer, has
introduced JM ocSPF insulation, a low-density polyurethane open-cell spray foam
insulation designed for commercial and residential applications. Recommended for
walls, floors, unvented and vented attics and ceilings, JM ocSPF insulation will
insulate cavities of any shape, creating a “seamless” protective air barrier
that minimizes or eliminates air leakage for maximum building envelope
performance. It is mold and mildew resistant, minimizes sound transmission and
provides an R-value of 3.8 at one inch, R-13 at 3.5 inches and R-19 at 5.5
inches. It is considered an air impermeable insulation at a thickness of 3.5
inches. It can be applied at up to 6 inches per pass and, when properly
installed, the product expands 120 times its initial volume, sealing all voids,
gaps and crevices.
Unlike many other open-cell
products on the market, JM ocSPF insulation is formulated with 100 percent
reactive catalysts to minimize emissions during spraying, resulting in lower
jobsite odor and improved safety for installers.
In addition, JM is introducing JM
IB Coating, an intumescent ignition barrier coating recommended for use over JM
ocSPF insulation in unvented attic and crawl space applications. JM IB Coating
is an effective ignition barrier over JM ocSPF insulation at a minimum
application rate of 0.6 gallons per 100 square feet.
“We’re excited to announce the
expansion of our spray foam product line with the launch of JM ocSPF
insulation,” said Mike Lawrence, vice president and general manager for JM’s
Insulation Systems business. “We’re introducing JM ocSPF insulation with our
customers in mind. Now, JM customers can order both fiber glass insulation and
closed- and open-cell foam efficiently from one manufacturer, and with the
reassurance that they are receiving quality products from Johns Manville.”
Available immediately, customers
are now able to order mixed trucks of JM ocSPF insulation and JM
Formaldehyde-free fiber glass insulation.
“What’s more, similar to our
premium closed-cell product, JM Corbond III spray foam insulation, JM ocSPF
insulation can be installed together with any of JM’s fiber glass building
insulation products to create systems that meet the demands of any project,”
Last summer JM introduced JM
Corbond III insulation, a premium high-yield closed-cell spray foam insulation
product. Also a polyurethane foam, JM Corbond III insulation can be used alone
or in hybrid systems to create customized insulation systems for residential,
commercial and industrial applications. JM Corbond III insulation offers the
highest yield of any closed-cell foam building insulation, providing 5,000 to
5,200 board feet of coverage per set.
JM ocSPF insulation maintains its
insulating performance over time. When properly installed, it adheres to a
variety of substrates and fills gaps and cracks that lead to air and heat
JM ocSPF insulation and JM IB
Coating will be initially distributed from the company’s Winder, Ga., and McPherson, Kan., manufacturing plants. JM ocSPF
insulation is recommended for Climate Zones 1, 2 and 3 and some portions of
Climate Zone 4, which includes the southern portion of the U.S. and the Pacific Coast. For more information, visit www.jm.com.
