Expanded Polystyrene Systems: Underwriters Laboratories Selected For Independent Testing

Carpenter Co is pleased to partner with Underwriters Laboratories of Northbrook, Illinois to provide independent third party testing of their expanded polystyrene material. Underwriters Laboratory will provide this testing for Carpenter’s compliance with ASTM standards C578, D6817 and E2430. Underwriters Laboratory also independently tests Carpenter’s expanded polystyrene for flame and smoke spread surface burning characteristics as well as insulation under Class A Single Membrane roofing systems.

“We are exciting about having such a well-respected, world renowned testing laboratory such as UL perform these on-going tests of our expanded polystyrene products” said Larry King, Vice President Insulation Division at Carpenter Co. “This testing assures our clients of only the highest quality material to achieve their insulation needs.”

Carpenter Co has expanded polystyrene production facilities in Fogelsville, PA, High Point, NC, Lakeland, FL and Elkhart, IN.
