Location: Baytown, TX
Coating: Mascoat WeatherBloc-IC
Thickness: 20 mils (0.5 mm)
Reason for application: Reduce radiant heat gain


After record-breaking summers in 2011 and 2012, companies have been looking for unique and innovative ways to keep their facilities’ internal temperatures more manageable. One such company is located in Baytown, TX and was unable to adequately control the temperature inside an energy control room. Even with conventional insulation and multiple air conditioning units, they were still getting too hot during the summer. On occasion, the heat would be so severe that it would trip the circuit breakers, causing the entire unit connected to the control room to automatically shutdown. It was vital to find a solution; an unscheduled shutdown could cost the plant hundreds of thousands of dollars.


In anticipation of another sweltering summer, the company asked their contractors, Brock Group, for suggestions. Brock had done quite a few projects with Mascoat in the past, so they contacted a Mascoat specialist for a recommendation. Mascoat recommended that 20 mils (0.5 mm) of their WeatherBloc-IC coating be put on the outside of the control buildings to help reduce the solar loading, decreasing the temperature in the control rooms.


To measure the performance of the WeatherBloc-IC, Brock only coated half of the roof of the first building on the first day of the project. The uncoated side had a surface temperature of 79°F (26.1°C) while the side coated with WeatherBloc-IC was 66°F (18.9°C). They were hoping to drop the surface temperature to 72–74°F (22.2–23.3°C), so dropping it to 66°F (18.9°C) was a very pleasant surprise.

Brock completed the project in May of 2013. To date, there haven’t been any shutdowns resulting from overheating in the Mascoat-coated control room and the plant has added Mascoat’s coatings in their plans for future projects.
