TruLo Max from Owens Corning is a low-odor, low-fuming asphalt for built-up roofing systems. It suppresses 90% of fumes at the kettle and reduces 55% more odor-causing compounds on application. The company cites a National Institute for Occupational Safety and Health study showing that the fume-reducing skim layers also reduce VOCs.
