Wondering about stability of hardwood flooring over garage
I have read that for flooring to be stable, that temperature and humidity must be controlled. Our family room is over our garage. Last year, all of the garage ceiling drywall and insullation was removed in order to do structural work. So now there is a plywood floor over the garage. Some work still remains to be done before the garage ceiling can be re insulated and redrywalled. Can i go ahead and install my hardwood flooring in the family room? I would like to use 4" wide boards, am open to engineered or solid hardwood.
We currently have just plywood underlayment in the family room. If i can't lay hardwood at yhis point, then i need to go ahead and carpet to get the room functional.
Thanks for any help and advice!
