BUR Roofing Systems

Johns Manville is not only a pioneer in developing BUR (Built-Up Roofing) systems, but we created the very first BUR system in America more than 150 years ago. Our continuous investment in developing materials and manufacturing techniques has taken that heritage to a new level, and today nearly one billion square feet of JM BUR systems are under guarantee.

Why use BUR over other products? Because few other systems are so long lasting, durable and worry free. With JM BUR systems, the highly reliable waterproof membrane is field fabricated with layers of bitumen, alternating with plies of reinforcing felts. The redundant layers give it exceptional resistance to water and weather. We also manufacture a complete line of fiber glass felts, including ply and base felts, and mineral-surfaced cap sheets.
