basement slab ?

bill_8

I'd like to put radiant in the basement, about 28 by 28 and 14 block high with a walk out. The slab is insulated below and on the sides with styrofoam. The room above will be heated with radiant panels. Supply water temp in the 115 degree range. These are some of the ideas others have come up with.

1. new pour over tubes held in place with rails
2. lay down more foam and use plastic clips to hold tube then new pour
3. sleeper system with sand over tubes between sleepers, then install wood subfloor
4. sleeper system using panels

any other deas?

What will the finish floor

covering be? This may hely you decide on a good method. The additional foam seems redundant if you have foam under the current slab.

An over the top product Wirsbo or Watts may work best for a quick responding system under hardwood. This would be the "thinnest" application. Thin dry applications like this are nice for fast heat up and cool down abilities.

A concrete overpour would like to have 2" over the top of the tube. a good way to go if tile willbe used. Floating hardwood also works on concrete slabs, but nail down hardwood would be a drag over a slab, and may require two layers of plywood for nailer. Lots of cost and labor for nail down hardwood. Slab over slab would be a slow responding system with all that concrete mass.

Gypcrete overpour could be poured thin but carpet is the only good covering over gyp products, in my opinion. Gyp also hates to get wet if this would ever be a concern in the basement.

Lots of options, weigh the pros and cons of each for your specfic project.
