Modified bitumen roofing systems used in Canada incorporating PlastiSpan insulation board have been engineered to provide optimum performance in Canada's harsh climate. This type of system is suitable for either new or maintenance roofing applications.

The popularity of modified bitumen roofing systems is increasing as more building designers and specifiers begin to specify these types of systems. Engineered modified bitumen roofing membranes originated in Europe in the mid 1960's and have been used successfully in Canada and the United States since approximately 1975.

Plasti-Fab’s EPS insulation is an excellent choice for roofing applications due to its long-term thermal resistance and performance qualities. With R-values ranging between 3.75 per inch to 4.7 per inch depending on the product used, it is a cost-effective thermal insulation that provides increased energy efficiency within the structure.

Various modified bitumen roof assemblies incorporating PlastiSpan insulation board have been tested for compliance with requirements for fire rated roof assemblies.
