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.
When is an Asphaltic System the Right Choice?
With the wide variety of roofing technologies available, an asphaltic solution can be your best choice when you’re looking for multi-ply redundancy, enhanced durability, proven performance, high wind uplift and fire-rated assemblies, lower long term performance risk for issued guarantees, high compatibility with other roofing systems, and simplified owner maintenance. Architects and consultants often specify asphaltic solutions for applications such as K-12 schools, higher education low slope buildings, hospitals, data centers, and high-profile federal government projects.
