Open-cell vs. closed-cell
Thanks Mr. Holladay for responding to my question however I don’t think I was clear with my question. I wanted to remove the floor installation it my atic and replace it with foam installation between the rafters. I’ve heard many different things about open & close cell that I didn’t know what was true or false. What is recommended for the atic ceiling, open or closed cell. What is R value and what number should I try to accomplish with the R value.
