Vinyl planks on concrete question
I will be installing golden select vinyl tile planks(Charleston grey) in my basement, which is concrete. The planks already have a foam like backing applied to the planks. In the golden select installation paper, it says minimum of 6mil vapour barrier applied on the concrete before installing the planks. The piece of plastic is like $100 for 1000sqft. But I want something that has more cushion and a little warmer for the basement. Can I use one of these instead of just a basic plastic sheet?
