Modified Bitumen



Modified Bitumen Roofing Systems are created when a polymer is added to asphalt to extend temperature limits and increase the pliability of asphalt.



There are two kinds of Modified Bitumen



Styrene Butadiene Styrene (SBS) – this type of modified bitumen roof is installed using cold adhesive or hot moppings of asphalt and can come with adhesive backing. Modified bitumen SBS has a rubber-like appearance.



Atactic Polypropylene (APP) – is a thermoplastic polymer that is either heat-welded or torch-applied and gives asphalt a plastic-like quality.



Both types of Modified Bitumen roofing can withstand both high and low temperatures due to polymer modification.

Features

Benefits



Modified Bitumen holds up well under UV exposure and can last up to 20 years with minimal maintenance.



The adhesives used to attach Modified Bitumen provide protection against water damage.



Modified Bitumen comes with an insulating layer that limits the flow of heat throughout the system helping to reduce energy consumption.
