Developed to improve energy efficiency and save on utility bills, the Mascoat WeatherBloc-HRC thermal insulating coating is a new insulation solution for commercial and industrial properties worldwide. Unlike reflective rooftop paints, the coating combines true thermal insulation with a durable reflective paint, so it offers thermal protection even on cloudy days.
WeatherBloc-HRC thermal insulating coating contains high-quality ceramic and silica particles encased in a high-grade acrylic emulsion. The result? A spray-on thermal insulating coating that reduces radiative and conducted heat to produce dramatic temperature differentials. The radiant barrier insulation product goes on like paint, and unlike reflective roof/sidewall coatings, it can be used underneath or on top of walls and roofs. When used on substrate exteriors, this ceramic roof coating resists weathering, reduces condensation, and lasts for years without reapplication.
