What type of roof is SBS?
SBS modified bitumen roofing is a material made out of asphalt and synthetic rubber, making it an exceptionally flexible material for flat roofs. Thanks to its rubber composition, the material is less prone to cracking and sustaining damage from elements like ice and sun.
What is SBS underlayment?
LeakBarrier SBS MultiPurpose Underlayment is a unique and highly versatile glass fiber reinforced sheet sandwiched between two layers of superior quality polymer modified bitumen.
What does SBS membrane mean?
Styrene-Butadiene-Styrene
Styrene-Butadiene-Styrene (SBS) describes a family of synthetic rubber derived from styrene and butadiene. SBS is a thermo plastic elastomer that has an excellent abrasion resistance and aging stability when blended with bitumen, making it the perfect bitumen modifier to achieve cold flexibility and elastic properties.
What is SBS cap sheet?
Tri-Ply® SBS Granule Cap Sheet is a granule-surfaced modified bitumen membrane manufactured to stringent GAF specifications. Its core is a strong, resilient, non-woven polyester mat that is coated with flexible, SBS polymer-modified asphalt and is surfaced with mineral granules.
What is an SBS system?
SBS Modified Bitumen Roofing Systems are popular for commercial or industrial buildings with low-sloped, asphalt based roofs. SBS, also known as styrene-butadiene-styrene, refers to the type of polymers that are added to the asphalt.
What is Firestone SBS?
Firestone SBS (styrene-butadiene-styrene) Modified Bitumen Roofing Systems incorporate a synthetic rubber-based technology that yields extraordinary flexibility, even in very low temperatures. SBS membranes can be installed with cold adhesive, hot asphalt, or they can be heat-welded.
How much does a roll of modified roofing weigh?
Weight: 78 lbs./roll.
How much does a roll of modified bitumen weigh?
Individual sheets of modified bitumen are typically between 120 mils (3.05 mm or 0.12 inches) and 180 mils (4.6 mm or 0.18 inches) thick. A typical sheet of modified bitumen roofing weighs about 1.1 lbs.
How is SBS applied?
SBS is the most customizable of our low-slope commercial roofing products with glass, polyester and composite reinforcements. It can be installed with the widest variety of application methods including cold applied, heat weld, self-adhered, mechanically fastened, and hot applied applications.
What is the difference between APP and SBS membrane?
APP membranes are used more often on smaller roofing areas because they flow more easily. SBS membranes can tolerate much lower temperatures, making them ideal for cold-weather areas. They also take less time to install and last longer.
What lasts longer EPDM or bitumen?
Shorter life expectancy The reality is that modified bitumen roof life expectancy is way shorter than that of EPDM. To maximize built up roof life expectancy, make sure to adhere the overlapping joints properly.
