TruLo® Max is the low-odor, low-fuming asphalt that delivers top roofing performance. The patent-pending technology not only neutralizes asphalt odor but also reduces up to 90% of the fumes at the kettle. (NIOSH Study). When compared to leading competitive low-odor asphalts and additives, TruLo® Max asphalt is 55% more effective at reducing odor-causing compounds. That’s because it was developed for use at even the most odor-sensitive sites like schools, restaurants, and hospitals.
