Safety Data Sheets
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.
Membrane Base & Cap Sheet Surfacing Options
Asphaltic base and cap sheets come in a wide range of surfacing options — including silica, talcum powder, polyolefin burn-off film, standard and bright white granules, embossed aluminum film, and more — to help accommodate your installation methods and meet your durability and reflectivity expectations.
