It developed a unique glazing procedure that allows the tiles to reflect the majority of solar heat. Solar Reflective Index (SRI) is a global measure of tiles’ solar heat reflection capability. Johnson’s Cool Roof tiles are a collection of one-of-a-kind tiles with an SRI value greater than 90. Thus, these tiles shield your building interiors from the sun's heat.
Cool roof and wall tiles have a special double-glazed coating that reflects sunlight and absorbs heat into the atmosphere. This allows for a cooler interior and savings on electricity bills.
