Spray Foam Insulation
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.

JM Corbond IV Canada
JM Corbond® IV Canada closed-cell spray polyurethane foam (SPF) is a next generation HFO blown, two-component, medium-density, SPF insulation system. JM Corbond IV Canada is designed to insulate commercial, residential, and industrial buildings. The HFO technology allows JM Corbond IV Canada to be produced with a low Global Warming Potential (GWP) and with an Ozone Depletion Potential (ODP) of zero. Its high-yield, superior thermal and moisture performance, and exceptional sprayability and adhesion make it an ideal choice for high-performing energy-efficient buildings.
