Super Therm
Super Therm® is a NASA-developed, water-based ceramic insulation coating that blocks roughly 96% of the total solar heat load in a single thin-film coat. Four sizes of micron ceramic particles reflect UV, visible, and infrared radiation before it's absorbed — so roofs, walls, tanks, and containers run dramatically cooler and your HVAC works far less.
Why it works
Traditional insulation only slows heat that has already entered. Super Therm reflects and blocks radiant heat right at the surface — a Solar Reflectance Index of 105 and 0.91 emissivity — cutting cooling energy use by up to 40% and keeping surfaces touch-cooler in full sun.
