We are currently looking into the passive solar design (newbies) and it appears that a concrete floor with radiant heat will help to hold heat within the house for the longest period of time. My wife is not a fan of concrete/tile floors within the main living areas of the house. Are there alternative options? We know how important the thermal mass is for maintaining heat during winter months. What about placing a vinyl corked backed flooring over the concrete floor?
We are looking to build a single-story house with a walk-out basement. Southern Ontario and we have full unobstructed southern sun exposure. Do you have any other tips to consider?
Thanks for any input in advance.
