    radiant heat and tile floors with lath

    Iam a tile contractor and I am getting mixed messages on the installation.I have 1"1/4 to finish floor with a tile thickness of 3/8". Ok--The plumbing contractor wants to put down bubble wrap under the tubes,I have concerns that it will make the floor a floating floor.Have you heard of plastic lath? If so would that go under the heat tubes or over them? What are the pros and cons of chicken wire verses metal lath? I would choose to put down 20lb. roof felt over plywood then metal lath then heat tubes then plastic lath ( if I can find it), mud float,anti-fracture/waterproof membrane,then thinset to ceramic tile. What do you think?

    Works fine here..

    I have tubing in pour-a-floor with schluter ditra over that, then limestone flooring.

    No problems yet, and limestone would crack in a heartbeat.

    Hilghly recommend ditra. Highly recommend your radiant installer knows his stuff (eg no 180 degree water at 20 GPM)

    However, still don't know what your question is?

    Tile floor

    1 1/4" to finish. I would install the tube on the plywood then float over it with a morter mix. Install a membrane of some sort so the tile will not crack. Run the water at about 100. Anyone have any ideas around this?

    radiant heat and tile floors

    My plumbing contractor wants to put down foil bubble wrap in the bathroom floor. There is hardwood every where else in the house even the kitchen. The run for the bathroom also goes to the kitchen.Thats one part and the other is I just dont like the fact that I have an air gap between my mud float and the plywood floor, especially in a bathroom. Have you heard of plastic lath?
