Atlas Wall CI is happy to announce some new additions to its rigid board polyiso wall insulation offering. Atlas Wall CI manufactures a quartet of exterior wall insulation products, but the addition of Infinish ES and Infinish ES2 represents the first interior-focused wall insulation boards to be manufactured by the company. 

Infinish ES and ES2 both feature a Class A fire rated closed cell polysiocyanurate foam core with an embossed and scrub-resistant acrylic coated aluminum foil facer on the front and a reflective foil facer on the back. Infinish ES2 also includes fiberglass fibers in the core to meet ASTM C1289 Type I, Class 2. Both insulation products have been developed for interior exposed applications.

“The addition of Infinish ES and ES2 expands our product reach by featuring products designed and approved for use without the normal code prescribed thermal barrier,” says Alec Minné, director of marketing Atlas Wall CI Division. “Both products have been approved per NFPA 286 on interior walls or interior ceilings, eliminating the need for drywall or other coverings.”

Infinish ES and ES2 can be used as an interior insulating finish on interior walls or ceilings, but not in combination. Applications include tilt-up masonry walls, wood or steel stud interior walls, pre-engineered metal buildings, post and beam buildings, below grade interior basement walls, and interior crawl spaces. Panel sizes are 4' by 8', 4' by 10', or 4' by 12'. Some custom sizes are also available. A 15-year limited thermal warranty is available.
