Johns Manville (JM), a Berkshire Hathaway company and leading building products manufacturer, has announced that its signature JM Spider® Spray-in custom fibre glass insulation has received Canadian Construction Materials Centre approval (CCMC 13212-R) for a thermal resistance of R-24 in a 2×6 wall cavity, complying with 2010 National Building Codes. The product previously offered a thermal resistance up to R-23 in a 2×6 wall cavity.
CCMC operates within the National Research Council of Canada and offers a national evaluation service for all types of innovative building construction materials, products, systems and services. CCMC evaluations are supported by the latest technical research and expertise and are based on the requirements of the National Building Code of Canada or Provincial/Territorial Building Codes.
“By increasing JM Spider’s thermal resistance from R-23 to R-24, we’re helping our Canadian customers more easily turn to this unique product – the only spray-in fibre glass insulation product available in Canada – to meet code for a range of project demands,” said Fred Stephan, senior vice president of Insulation Systems at Johns Manville. “This is just another way we’re offering our Canadian customers more options and greater flexibility.”
