Sbs Vs App Modified Bitumen Roofing

Sometimes bitumen roofing products like asphalt shingles can be recycled and used to construct new roads.

Sbs vs app modified bitumen roofing.

Sbs modified bitumen consists of bitumen with a synthetic rubber modification adding styrene butadiene stryrene sbs. Learn about modified bitumen sbs roofing systems. There are notable differences between the two materials and their application methods. 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.

App are bitumen composed of plastomer. 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. This means that the bitumen have been processed with an elastic plastic which makes them flexible at certain ambient temperatures. The modified bitumen seals down to the roof so there are no seams.

Four decades ago modified bitumen came along as an upgrade over traditional asphalt roofs. This means that app bitumen roof coverings are more resistant to the sun and uv radiation than sbs bitumen roof coverings. Sbs modified bitumen roofing systems are popular choices for low slope commercial industrial and institutional buildings when an asphalt system is desired. One beneficial aspect is that.

Get to know more about one of the most popular commercial roofing systems. Exploring app and sbs modified bitumen roofs the two most commonly added modifiers are app and sbs. 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. Atactic polypropylene app is a plastic which when used with asphalt gives what s commonly called plastic asphalt.

This does not melt in the same way as app instead offering a sticky melt which increases the hotter it gets. This lack of liquid flow means it takes less heat to install and allows a faster installation compared to app. When torching app roofing membranes the bitumen begins to flow like candle wax when it reaches temperatures above 300 f. 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.

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