Question: Do you have STC data on 2" foam board?
David writes from Allison Park, Pennsylvania: "I know that Foamular 150 is not meant for sound control - but do you have the STC data on the 2" board?"
Answer: STC (Sound Transmission Class) is an assembly rating. Fiberglass and foam insulation and other individual products do not carry STC ratings alone. Owens Corning does not have information comparing general assemblies using FOAMULAR® extruded polystyrene foam insulation.
