My house was built in 1994. I already have unfaced insulation in my crawl space running North to South. Can I put more insulation running East to West over the existing insulation? If so, what kind should I purchase? I was told by one sales person at Lowes that I can get R-13 (faced) and install it over the existing insulation with the faced part down. Then on another day another sales person at Lowes told me that I should install a moisture barrier and then I could use non faced insulation. I do not have a moisture barrier under my house and now I'm confused to what to do. The ultimate goal is to insulate my crawl space properly. What is the proper way to do it to keep my energy cost very very low?
I had a leak/flood recently, had to get rid of old linoleum and carpet. Now the concrete floor is exposed. Fans dried out the place for 4-6 days. I want to put engineered wood flooring on top of the concrete slab. Due to the moisture from flood, do you recommend just a moisture barrier sealer, or sheetings before putting on the flooring? How about plywood first? The place was soaked overnight. Moisture crept up walls 8 inches. I heard it's good to put plywood planks first, or a vapour barrier to seal concrete first. For the sealer, the flooring guy wants $1000, isn't that excessive?
My house is 20 years old. Do I need a moisture barrier or vapor barrier to be used before installing wood flooring? I've heard a million different opinions. I want to use Boston's Best, I've been assured that is all I need.
