New Radiant Job for Maine

is a slab on grade summer place in Maine to be built in the spring. We are going radiant all the way with this one. My son and I will be building together.

Here is my question: What is the best flooring to be placed over a cement floor with tubing set 4" below surface.

The kitchen and bath are going to be some brand of ceramic any suggestions welcomed.

The main floor area will be wood again looking for suggestions.

The last thing is the bedrooms are going to be carpeted again what can we do to insure good heat transfer with carpet.

I look forward to your suggestions.


  • for carpet, you want a slab rubber pad, and thin synthetic carpet on top if possible.

    for wood, what you can get away with depends on your heat load, and you need to make sure one is done before you put a foot of pipe in that home. The best is an engineered floating floor, if possible.

    I don't know particular tile products, but any tile product is a good match over radiant.

    Make sure that slab gets insulated!

    radiant in Maine

    Tim, we do quite a bit of radiant up here in Maine, and basically, you can use any floor covering you want. However, you have to design for it and may need multiple zones with multiple temps and possibly some supplemental heat or wall radiant to make up the difference. We use -20* as design low temp up hear, 'cause it gets damn cold. Just plan ahead and pick floor coverings before doing heat calcs, no after. Where in Maine?

    make sure the

    carpet and pads r value is below 2.5 or you could have some problems. as far as hardwood, it should be a floating floor.

    If you go with a floating wood floor take a look at Kahrs it can be refinished twice and is very stable with radiant.

    Slab Edge

    Tim, make damn sure there is good slab edge insulation. You probably already know this, but I have seen far too many that weren't - U$$$$$$GLY.

  • Al it is located

    in Bridgton, Maine. Thanks everyone for all the good advice so far. All of the jobs we have done in RI and Mass we have super insulated the outer walls and ground area. They have all been great so far.

    Floor coverings have been something I have discovered can become a problem after the fact as people add things not planned for. We just want to get all the input from as many people as we can about possible problems or things they have run into.

    It is interesting two of the floor covering stores I visited did not even know that radiant in floor heating existed and obviously had no idea what to recommend. We will be shopping elsewhere I am sure.

    Bridgton is one of those areas in Maine that can get really cold even when other areas are relatively warm. Its neighbor, Fryeburg is routinely one of the coldest places in Maine!!!!
