Johns Manville – 150 Years of Innovation

Johns Manville (JM), a Berkshire Hathaway company, is celebrating its 150th year in business this year by reaffirming the company’s commitment to the sustainability of their products and the health and well-being of the structures their products are used in.

JM is perhaps best known for its building insulation, but the company is also a leading manufacturer of premium-quality commercial roofing, roof insulation and specialty products for commercial, industrial and residential applications. JM’s product offerings include mats and fiber glass reinforcement products, some of which are used in today’s mold-resistant wall board.

Within the insulation market JM is widely recognized as the only manufacturer to offer a full line of Formaldehyde-free™ fiber glass building insulation. In addition to helping builders, contractors and homeowners achieve better indoor air quality JM strives to source sustainable raw materials. For the company’s fiber glass, JM uses 20 percent post-consumer recycled glass and 5 percent post-industrial glass.

As Johns Manville embarks on its next 150 years in business, the company is committed to manufacturing sustainable energy efficient products that contribute to the health and well-being of building occupants.
