Butyl Roof Coatings


How Butyl Roof Coatings Work

Butyl roof coatings are used for all types of roofing substates. This rubber elastomeric coating provides most systems with durable, seamless membrane that provides excellent UV protection and superb resistance to moisture penetration. While butyl roof coatings can be used for a variety of different applications, how do they benefit a commercial building owner or facility manager?

Butyl roof coatings are probably best known for their elongation properties. This means the coating, once cured, will withstand natural expansion and contraction of the roof. Butyl roof coatings also serve as a vapor retardant coating, making it ideal for use over spray polyurethane foam in cold storage or freezer applications. With its excellent reflective properties, butyl roof coatings can also reflect 80-90% of harmful UV rays, which can drastically cut down on energy cost.

Installing Butyl Roof Coatings

Depending on the roof type and application, a tank spreader or airless sprayer can be used to achieve the greatest amount of coverage when applying a butyl roof coating. For details such as seams, fasteners, penetrations, and transitions, a brush or bulk gun is typically used. Click here to learn more about roof coatings equipment.
