SBS, APP & BUR roof system product comparisons

Any discussion on asphaltic roofing will involve one or more of these three terms: SBS (Styrene-Butadiene-Styrene), APP (Atactic Polypropylene), and BUR (Built-up roofing). SBS and APP are polymers with unique characteristics, and membranes made with them are classified by ASTM numbers, types and grades. BUR is an assembly method in which multiple layers of felts are installed with hot asphalt in-between.
