Plates with sleepers

Wayco Wayne

with a carpenter on a radiant floor. I'm going to put rti plates on top on the sub floor with 7 inch wide sleepers in between the tube, on top of the flanges of the plates. Does any one have suggestions as to how to handle the U-turns at the end of each straightaway. Thanks in advance. WW

    Wayne-

    This will depend upon the fihished floor covering. If you are using hardwood, just knock the corners off. It doesn't need to be exact as the strength of the hardwood for small crack will be able to handle the weight.

    The second choice is to router a 4" wide strip of plywood for your 8" on-center spacing. If using 3/8" PEX, use a 1/2" or 5/8" router. Again the neatness is not that imperative.

    If using a tile floor, the mastic will fill in the gaps.

    If using a carpeted floor, a thin 1/4" ply or luan would do the trick.

    I'm glad you asked. As a DIY I am doing the same thing and was afraid I was getting into something weird that maybe wouldn't work. I have heard you could put thinset in the curves to improve conduction to the finished floor.

    I will be doing from bottom up, slab, 1/2" foil faced isocyanurate, Thermofin-C, 7" wide (3/4") ply sleepers over the flanges, 3/4" wood finished floor.

    How are you going to nail the ply and flanges down to the slab ? I haven't figured that out yet.

    Actually

    I am screwing the plates to the existing sub floor which is 3/4 plywood. Not sure how I would deal with a slab in this scenario. WW
