The results are in – and EnergyShield^® XR is now approved for even more NFPA 285 assemblies and additional cladding options to support safe, more versatile building designs.

Originally developed to offer a superior option to XPS while meeting the flexibility of both residential and commercial, above- and below-grade needs, the latest fire performance test results mean that EnergyShield^® XR can now be used within millions more NFPA 285 assemblies. According to DrJ TER 1306-03 (now live at DrJ Engineering), among the new options are exterior claddings, like metal panels and fiber cement; additional WRB and sheathing options; and more. Expanded NFPA 285 approved assemblies offer engineers and architects greater design versatility and flexibility for substitution requests that add value to projects. 

EnergyShield^® XR continues to build upon a portfolio of assemblies and uses unreachable by XPS. “We continue to expand the capabilities of our EnergyShield^® XR product because it creates more versatility of use and allows us to continue our efforts to focus on customer needs,” said Jen Frey, senior product manager, Atlas. “By offering a one-size-fits-all product like EnergyShield^® XR, we help add back efficiencies when selecting polyiso for a project. By offering a wider range of tested assemblies, EnergyShield^® XR can better help meet the demands of increasingly stringent fire safety codes while accommodating innovative construction methods and energy efficiency goals.”

EnergyShield XR, perfect for residential or commercial applications, is available nationwide from eight North American manufacturing facilities; more information may be found here.
