Johns Manville

Johns Manville has released its Cool Roof Granulated (CR G) cap sheet portfolio. The new cap sheets combine the installation ease of a standard granulated cap sheet with the energy-efficient benefits that come from a highly reflective and emissive surface. The cap sheets are surfaced with a bright-white, highly reflective granule that’s both durable and energy efficient. The granule mitigates solar heat and provides additional comfort to the interiors of the buildings it protects. This latest addition is the most cost-effective cool-roof product option from JM for modified bitumen systems to date. In addition to the new membranes, 5-gallon containers of Cool Roof Granules have also been added to the product offering and are packaged to dress up bleed-out at seams when desired for a superior finished roof surface.
