Hi all,
I'd like your thoughts on which of these options would be best for a basement subfloor. We recently purchased a house with a finished basement (minus the floor) which was ripped out due to a water softener tank bursting and flooding the basement. When we had the house inspected, no moisture issues were detected in the basement. The walls are finished but the flooring is down to the slab. We are planning on having 10mm laminate installed on the subfloor. Here are the options I've been provided with from our contractor from least to most expensive:
5/8" T&G OSB over platon with all joints and perimeter sealed
5/8" T&G spruce ply over platon with all joints and perimeter sealed
Dri-Core
5/8" T&G OSB over 1" rigid foam
5/8" T&G spruce ply over 1" rigid foam
We live outside of Toronto so it gets cold here in winter. My husband works from home and is in his basement office all day. I want something that will keep the room feeling warm so I'm thinking the 5/8" T&G spruce ply over 1" rigid foam is the best option. From what I've read in other threads, it sounds like laying 6 mil poly under the foam would also be a good idea to prevent any possible moisture issues. However, there is a $700 difference between the least expensive and most expensive options. I want to make sure that the price difference is worth it. Any thoughts on this?
