Atlas® Roofing Corporation has announced the launch of its StormMaster® Core4™ Enhanced Polymer Technology. Available exclusively in Atlas StormMaster Shake and StormMaster Slate shingles, Core4 is one of the most innovative developments in asphalt shingle manufacturing on the market today. In the early 1990s, Atlas was one of the first companies to manufacture polymer-modified asphalt shingles, known as SBS asphalt technology. Core4 moves beyond SBS to a more enhanced, proprietary polymer technology.
As its name implies, StormMaster Core4 Enhanced Polymer Technology consists of four key features. PolyCore™ Technology is the science and engineering behind Core4. Made from proprietary enhanced virgin polymers, shingles with Core4 are stronger and longer lasting than other leading brands, allowing them to perform better with increased consistency and reduced variability.
FlexCore™ Technology keeps shingles flexible in cold weather. Because of their elasticity, these shingles exceed the industry’s standard tear strength by 50% and lay flatter during installation so they seal more effectively. They’re also less susceptible to tearing and cracking, which can lead to blow offs, leaks, and compromised long-term roof stability.
WeatherCore™ Technology gives shingles the durability they need to resist damage from hail and high winds. StormMaster shingles with Core4 pass the UL 2218 Class 4 Impact Rating and offer the highest wind warranty in the industry, with up to a 150 mph wind limited warranty with special application on StormMaster Shake.
ThermalCore™ Technology mitigates the effects of shingle expansion and contraction due to temperature change, also known as thermal shock. Thanks to this enhancement, shingles with Core4 are less prone to thermal stress degradation that can lead to premature shedding of granules, resulting in accelerated aging and deterioration of the asphalt shingle system.
Core4 is available within the Atlas premium StormMaster Shake and StormMaster Slate shingle lines, which provide architectural style along with the durability to stand up to the toughest weather conditions. StormMaster shingles also feature the power of Scotchgard™ Protector by 3M, which resists the black streaks caused by algae.
