Membrane Benefits

Top Spec by WeatherBond TPO membranes are enhanced with WeatherBond’s OctaGuard XT™ Weathering Package resulting in the most dependable, long-term performance characteristics in the industry. TopSpec by WeatherBond TPO membranes carry the ENERGY STAR®* qualification, which exceeds the stringent program guidelines based upon solar reflection and heat emittance. Additionally, TopSpec by WeatherBond TPO is listed as a CRRC (Cool Roof Rating Council) certified product that meets Title 24 mandates for the state of California.

Top Spec by WeatherBond’s ENERGY STAR-qualified TopSpec by WeatherBond TPO membranes with their high reflectivity ratings help reduce the amount of energy required to maintain cool building environments. Less energy consumed reduces pollutants generated into the atmosphere, (reducing the Urban Heat Island Effect) and results in a cleaner, cooler environment.

Membrane Flexibility

TPO polymer is flexible in its original state, prior to being converted to a membrane. This natural flexibility is maintained as the TPO membrane is exposed to extreme heat and UV. Also, this sheeting easily accommodates a building’s normal expansion and contraction.

Chemical Resistance

Top Spec by WeatherBond TPO membrane is highly chemical and contaminant resistant. Most liquids and chemicals exhausted onto the roof have no effect on the membrane.

Fire Resistance

Top Spec by WeatherBond TPO roofing systems meets UL 790 requirements for external fire Class A ratings and UL P assemblies for internal, hourly fire ratings. Consult the UL Building Material Directory for specific assemblies.

Wind Resistance

Top Spec by WeatherBond TPO roofing has surpassed many of Factory Mutual’s wind resistance classification, which consist of the most stringent standards in the industry.
