SBS Roofing Systems – Types, Manufacturing & Benefits
When talking about SBS (Styrene Butadiene Styrene) modified bitumen roofs, first thing we need to consider is their amazing resistance. They are quite strong as they are based on glass-reinforced polyester mat. In terms of the color, you can choose between black, white and similar nuances.
Roofers use hot asphalt, cold-applied adhesives, heat welding and mechanical attachment to put them in place. Keep in mind that these systems are based on two-ply where first role goes over the edge of the second role. While application methods are pretty straightforward, it is better to rely on assistance of a professional roofer.
Main types of modified bitumen roofs
Homeowner can choose between two different types of modified bitumen roofs: previously mentioned SBS and APP. If you’re interested in this kind of a product, you first need to consider its advantages over APP.
Basically, SBS is known as elastic asphalt while APP is known as plastic asphalt. In other words, plastic is used to product APP while synthetic rubber is used for SBS. This is very important during application as Styrene Butadiene Styrene requires much less heat to be applied. This makes the whole process easier for roofers and quicker. As a homeowner, this simplifies everything and you will get a better end result because of it.
Roofers rely on either conventional or inverted application for SBS roofs.
How are SBS roofs manufactured?
First, manufacturers start with a standard roofing asphalt that is later on changed with modifiers. This is primarily done so that plasticizers can be replaced. Then, bitumen is strengthened with either polyester fiber or fiberglass. This increases its strength and durability.
When adding SBS or styrene-butadiene-styrene, the flexibility of membrane is significantly increased making it much easier to apply.
What are the main benefits of the product?
There are lots of reasons why homeowners prefer this roofing material. Here are some of the main benefits of choosing this particular product:
- SBS is very strong and durable
- If there is any damage to it, the roof can easily be repaired
- It is much easier to install
- It is easier for companies to control quality of this roofing material compared to some others (making it much more reliant)
- High water resistance
All of this reasons make Styrene Butadiene Styrene modified bitumen roofs some of the best on the market.
