Sbs Vs App Modified Bitumen Roofing

The term modified refers to the addition of substances like atactic polypropylene app or styrene butadiene styrene sbs that were intended to enhance longevity and flexibility compared to regular asphalt roofs.

Sbs vs app modified bitumen roofing. Learn about modified bitumen sbs roofing systems. Atactic polypropylene app is a plastic which when used with asphalt gives what s commonly called plastic asphalt. App are bitumen composed of plastomer. This does not melt in the same way as app instead offering a sticky melt which increases the hotter it gets.

App vs sbs modified bitumen roofing compared to sbs modified bitumen which has synthetic rubber added to it app modified bitumen has a higher melting point. Four decades ago modified bitumen came along as an upgrade over traditional asphalt roofs. There are notable differences between the two materials and their application methods. This means that the bitumen have been processed with an elastic plastic which makes them flexible at certain ambient temperatures.

No matter what type of method was used to install the modified bitumen they all have on thing in common that is a good seal. Sbs modified bitumen roofing systems are popular choices for low slope commercial industrial and institutional buildings when an asphalt system is desired. Because app modified bitumen is modified with plastic in the form of app atactic polypropylene and sbs modified bitumen is modified with synthetic rubber in the form of sbs styrene butadiene styrene. Sometimes bitumen roofing products like asphalt shingles can be recycled and used to construct new roads.

This means that app bitumen roof coverings are more resistant to the sun and uv radiation than sbs bitumen roof coverings. In addition to providing beauty affordability and reliability these systems are trusted to perform exceptionally well against extreme weather conditions. When torching app roofing membranes the bitumen begins to flow like candle wax when it reaches temperatures above 300 f. Exploring app and sbs modified bitumen roofs the two most commonly added modifiers are app and sbs.

Sbs modified bitumen consists of bitumen with a synthetic rubber modification adding styrene butadiene stryrene sbs. The modified bitumen seals down to the roof so there are no seams. Get to know more about one of the most popular commercial roofing systems. This lack of liquid flow means it takes less heat to install and allows a faster installation compared to app.

App is also better at withstanding damage from uv rays making it less likely than sbs to blister or crack.
