ThermalStar DripWave from Atlas Roofing

Atlas Roofing’s ThermalStar DripWave is an expanded polystyrene insulation designed for exterior one-coat stucco wall assemblies. Designed for high-moisture environments, the wall system features a patented vertically oriented wave pattern that creates a controlled drainage space between the insulation and the water-resistive barrier to channel water downward for drying and improve long-term durability for the wall assembly. It is available in 2-foot-by-8-foot and 4-foot- by-8-foot panel sizes, with thicknesses ranging from 1 to 1-1/2 inches for open wall framing and one half to 1-1/2 inches for sheathed wall applications.
