Modified Bituminous Membranes – SBS (Torch On)

torch-onModified Bitumen Roofing, commonly known as “torch on roofing”, was born out of the desire to improve bitumen’s waterproofing characteristics by adding rubber (SBS) to the bitumen.

A SBS blend is more elastic than bitumen. The blend performs better when a roof is exposed to significant increases or decreases in ambient temperature over short periods in time.

The heat of a torch or hot asphalt is used to fuse layers of SBS membranes together creating the roof system. Alternatively, adhesives or more expensive self-adhered membranes are used to adhere the layers together.
