Building Insulation Available in Canada

Johns Manville Formaldehyde-free™ fibreglass insulation provides thermal and accoustical control for both vertical and horizontal applications. Unfaced fibreglass insulation is available in a wide range of thermal resistance R-values.

Johns Manville Polyiso foam continuous insulation boards provide a layer of insulation to reduce thermal bridging and improve energy efficiency. Polyiso consists of a uniform closed-cell polyisocyanurate foam core and provides one of the highest R-values per inch of any rigid insulation.

Johns Manville Mineral Wool batts are made of inorganic fibres derived from basalt, a volcanic rock and are enhanced with glass fibres. Our advanced manufacturing technology ensures consistent product quality, with high-fibre density and low shot content for excellent performance.

John Manville's complete line of spray polyurethane foam (SPF) insulation solutions provides superior thermal energy efficiency, as well as advanced air and sound control. SPF insulation completely covers gaps and voids, works in hard-to-insulate areas and can exceed the performance of traditional fibreglass insulation. Both Johns Manville SPF product categories, open-cell and closed cell, deliver high yield, superior performance and exceptional sprayability.
