Cellofoam® expanded polystyrene (EPS) insulation provides a low-cost, durable, and energy-efficient solution for roofing insulation. Our insulation can be applied directly atop typical metal roof decks without a thermal barrier per 2015 International Building Code (IBC). Such “direct-to-deck” metal roof applications are commonly used in commercial buildings and save both material and labor costs. Cellofoam’s EPS insulations generally have a lower cost per R-value and a more stable R-Value over time than competing Polyisocyanurate and Extruded Polystyrene alternatives. Containing no ozone-depleting blowing agents, EPS is also environmentally friendly and is available with pre-consumer recycled content for use in LEED-certified and other green building projects.

Cellofoam North America Inc is proud to have helped sponsor industry testing of EPS insulated roofing assemblies for UL 1256 through the EPS Molders Association (now called the EPS Industry Alliance). Test reports on fire tests of EPS roofing systems applied directly to fluted metal deck, Roof Construction No. 458, were conducted by Underwriters Laboratories LLC, File R18302, Project 96NK14112.
