Advantech sub-floor with tile and radiant heat
New construction – I installed 1 inch Advantech and debating which way to heat SF one floor home and plumber suggested pex radiant heat under sub-floor with the alluminum heat shields. When he suggested it, I dismissed the idea as were thinking using 3/4 inch TG oak floors with the logic of how would heat go thru 1 3/4 inches in this Zone 5 house. But thinking we may put down large 24×24 tile which has a nice cement gray type of appearance, that maybe being 3/8 to 1/2 in thick, that the plumbers idea may work and use ductless to cool and backup heat. Have a 1000 gallon propane burried tank and will have some type of boiler.
I would also like to edit this to add spray foam and maybe rockwool insulaton
will cover the pex and there is a full walk out basement below that is not finished. Someone suggested that even though the basement slab is not insulated, I should still insulated the basement walls
