What is the difference between APP and SBS roofing?
The basic difference between SBS and APP is that APP-modified bitumen is a “plastic asphalt” and SBS-modified bitumen is an “elastic asphalt.” Why? When torching APP roofing membranes, the bitumen begins to flow like candle wax when it reaches temperatures above 300°F.
What is App roof membrane?
The APP membrane, short for Atactic Polypropylene Membrane, is a special waterproofing material that is manufactured from Bitumen. It is a common waterproofing material used on concrete flat roofs (which are still roofs) or roofs with low pitch.
What is APP-modified bitumen?
APP-modified bitumen is a roofing membrane. Contractors typically apply these membranes to asphalt with a torch. The process looks a little similar to mopping, as the contractor must spread the membrane across all sections of the roof. Once applied, you can choose to leave the roof’s surface smooth or add granules.
What is modified bituminous membrane roofing?
Modified Bitumen (MB) roofing is an asphalt-based, close cousin of the Built-up-Roof (BUR) designed for buildings with low-slope or “flat” roof structures. Modified Bitumen Roofing Systems are designed to withstand harsh exposure to extreme environmental elements.
What does SBS roofing membrane mean?
styrene-butadiene-styrene
SBS, also known as styrene-butadiene-styrene, refers to the type of polymers that are added to the asphalt. SBS is a thermoplastic elastomer that’s resistant to harsh abrasions, making it an extremely long-lasting membrane when blended with bitumen, also known as asphalt.

What is SBS modified roofing?
SBS Modified Bitumen Roofing Systems are popular for commercial or industrial buildings with low-sloped, asphalt based roofs. SBS is a thermoplastic elastomer that’s resistant to harsh abrasions, making it an extremely long-lasting membrane when blended with bitumen, also known as asphalt.
What is SBS and APP?
Atactic polypropylene (APP) is a plastic which when used with asphalt, gives what’s commonly called ‘plastic asphalt’. On the other hand, styrene-butadiene-styrene (SBS) is a synthetic rubber, creating the ‘elastic asphalt’. These. Modified Bitumen systems continue to be popular for a variety of reasons.
What is a SBS roof?
SBS modified bitumen roofing is a material made out of asphalt and synthetic rubber, making it an exceptionally flexible material for flat roofs. This material works best on low-slope commercial roofs, and many manufacturers use glass, polyester, or composite reinforcements.
What is SBS roofing membrane?
What is a SBS system?
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.
