Re: A Few Pics From A Radiant Project

Hey ERheating! My guess is that it is a matter of preference. Years ago as a helper, one of the first days on the job was an inslab radiant laydown. My "boss" handed me a cardboard box full of zip ties and said "follow behind me and every 1ft and a half zip tie the tubing to the mesh". Several radiant jobs later, on day I said why don't we use the metal ties and the tool the concrete guys use? He grumbled and said " because it's not good for the tubing". But it's ok for it be tied to wire mesh? Translation, he didn't have a good reason, possibly because he never thought of it. So that's all we've ever used. I've never read anywhere not too, and even some manufactures of radiant tubing sell the wire ties and tool to install it. To me that's a green lite to use it. The last several radiant jobs have been staple ups. Not much new construction going on around here for inslabs.

One to tie the tubing down, one to get into the concrete for reinforcement.

Re: A Few Pics From A Radiant Project

we just did a project like that but instead of gluing down the hard wood we ran 2x6 16oc pex was ran for floor heating, and we poured concrete in the bay. This was for a sun room off the kitchen. we waited a few weeks for the concrete to cure for a while before the flooring guy laid the hardwood. Now that its cold they just turned on the heat and the floor just started buckling a little bit. Hopefully it relaxes other wise we are going to have to rip the floor out.

Im not a hardwood expert but i dont think wood with a direct contact with concrete is a good idea
