flooring over a concrete slab foundation
We are about to build a new cottage that will have a slab on grade with 4 foot frost walls . The problem I have is trying to get info on how to install hardwood floors over the slab and marrying them to the tile that will cover the kitchen and other areas on that level such as the bathroom and utility room which will also be tiled . So far I've been told to use those 2' X 2' underlayment " tiles" with the vapor barrier on one side , or use a sub-floor i.e. 2x4 , insulation in between and plywood on top and then the hardwood on top . No suggestions for the ceramic tile areas other than to build up the slab in those areas .
I would like to think that there is a simpler way . Any thoughts ? Also we are in Nova Scotia , where the temperature varies from 0 F to 90 F and there would be periods of time in the winter when the cottage would be unheated .
