What does SBS Modified mean?

What does SBS Modified mean?

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 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 a modified roofing system?

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. With five layers of protection, it’s one of the most trusted flat roofing systems used in the industry today.

What does SBS roofing membrane mean?

Styrene Butadiene Styrene
The abbreviation for Styrene Butadiene Styrene is SBS. SBS are bitumen composed of elastomer. This material is a plastic that already has the elastic properties. When choosing SBS bitumen, a layer of gravel / slate over the roofing will have to be protected.

What is SBS roofing made of?

modified bitumen roofing
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 roofing membrane?

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.

Is EPDM the same as modified bitumen?

Both EPDM & Modified Bitumen offer benefits to the flat roofing industry. Modbit tends to be less expensive and offer more aesthetically appealing options, while EPDM is more environmentally friendly, easier to install, and tends to have a longer life cycle when installed correctly.

What is modified membrane?

Modified bitumen is made by adding polymers to the asphalt and combining that with a fiberglass or polyester reinforcement. The result is an impermeable roof membrane. Modified bitumen roofing provides superior weatherproofing protection and durability compared to conventional asphalt built-up roofing (BUR).

How long do modified bitumen roofs last?

approximately twenty years
It is important to notes that modified bitumen roofs have a solid roof lifetime of approximately twenty years. This is an estimate that does not include good roofing maintenance.

What are the advantages of SBS system?

SBS rubber is flexible and has the memory to return to its original form. The addition of SBS rubber to asphalt increases the flow characteristics and improves the low-temperature flexibility and fatigue resistance of roofing asphalt. The end product is a high-performance, 2-3 ply system.
