Product Details

SBS-modified bitumen membrane is made by saturating the base in bitumen, or thermoplastic elastomer (such as styrene butadiene-SBS), reinforcing with polyester or fiberglass, finishing the upward face with fine sands, mineral slates(or grains) or polythene membrane, etc.


 Good impermeability; Possess good tensile strength, elongation rate, and size stability which could be well suited the substrate distortion and crack; SBS-modified bitumen membrane is especially applied in a cold area with low temperature, while APP modified bitumen membrane is used in a hot place with high temperature; Good performance in anti-puncture, anti-broker, anti-resistance, anti-erosion, anti-mildew, anti-weathering; Construction is convenient, the melt method can operate in four seasons, joints are reliable

Size / rollWidth: 100cm
Length: 8m / 10m / 15m..(normal is 10m per roll)

Apply methoda) One way is by heating and melting methods. Heat the polyethylene film of the membrane and roof deck surface by heating and melting method to be nearly melted (not flowing), then install the membrane filly bonded to the roof deck with overlaps of 5-10cm.
b) The other way is by the cold adhesive method. Pour the cold adhesive homogeneously on the roof deck, then roll the membrane to install it to be fully stuck to the roof deck.
By heating and melting method and by cold adhesive can be used in alternation in the application as requested.                                             

Applicable scope:

Suitable for civil building roofing, underground, bridge, parking, pool, and tunnel in the line of waterproofing and dampproof, especially for building under high temperatures. According to the roofing engineering stipulation, APP-modified bitumen membrane could be used in the Grade Ⅰ civil building and industrial buildings with special waterproofing requirements.

Storage and transportation instructions
When storage and transportation, Different types and sizes of products shall be stacked separately, and should not be mixed. Storage temperature should not be above 50℃, the height is not more than two layers, and in the course of transportation, the membrane must stand.

With over two decades of experience producing modified bitumen, we understand the science of formulating systems that last.

Our SBS is a premium modified bitumen engineered specifically for elasticity. It is made to withstand even the harshest environments.

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 an SBS Roofing 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.

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.

As mentioned, SBS roofing membrane has the ability to retain its shape even after being stretched and scraped, and therefore, is widely used in modified bitumen roofing, coatings, sealants, and paving. SBS is also among the most popular roofing membranes used today and is trusted to perform exceptionally well against Toronto’s harsh winter weather.

SBS Installation
Not only is SBS one of the simplest commercial roofing system membranes to install, it’s also one of the most customizable. During installation, a variety of reinforcements are used with the asphalt, including fiberglass, polyester mats, scrims, etc.

In addition, SBS can be installed with a variety of application methods including cold applied, heat weld, self-adhered, mechanically fastened, and hot applied applications. Regardless of the installation type, properly modifying asphalt with SBS will give your roof a highly durable blend with exceptional recovery properties over a wide range of temperatures and weather conditions.

In short, asphalt modified with SBS proves to be among the best solutions for new construction design.

Advantages of SBS Roofing Systems

  1. Highly compatible with all types of flat roofing applications.
  2. Extremely resistant to harsh weather conditions such as high and low temperatures, rain, snow and sleet, and ice, making it very practical for commercial properties across the Greater Toronto Area.
  3. Longevity. The lifespan of SBS Bitumen Membrane is truly remarkable, even after aging and general wear and tear. Additionally, an SBS roofing system can further extend the longevity of a bituminous flat roof when it’s nearing the end of its service life. For example, a single layer can be installed over the top of the existing system to extend its lifespan.
  4. Water-resistant. With an SBS bitumen blend, your roof (and property as a whole) will be even more resilient to leaks and water damage.
  5. Simple installation with a variety of application methods to choose from.
