Hi, I am new to the forum and hope to get some helpful answers. I want to insulate the outside of my old house (built in 1929) with styrofoam boards. For cost reasons, I want to buy the styrofoam boards myself and provide them to my craftsman. You can get very cheap styrofoam boards on the internet, which would only cost me half of what my craftsman charges. Now I would be interested to know if there are possibly quality differences, are the cheap boards any good? I thought all styrofoam boards are the same and you only have to look at the WLG, or am I mistaken? What do the experts think?
