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.
Asphaltic Membrane Installation Methods
One of the many reasons asphaltic roofing remains so popular is the wide variety of installation methods available. Depending on specifications, building characteristics and use cases, asphalt roofs can be hot-mopped, heat-welded/torch-applied, cold-applied (adhered), self-adhered, or mechanically attached. Find more about these techniques.
