in THE MAIN WALL
I am interested in installing a radiant system over an existing slab. I'd like to not pour gypcrete over, keep retro fit thin as possible. Any suggestions. Also interested in converting upper level of home to radiant. I have 16" floor truss system and celing below is already drywalled. Can I use similar product upstairs and add thin insulation or just alum heat plate?
appreciate any ideas suggestions.

    Re: radiant retro

    Is the slab fully insulated under it, if so you might be able to do Quick trac on top of slab, appx 1/2" thick and then lay subfloor and floor over this. same with the top of joist system. Maybe blow in insulation through sub floor as long as you have IC can lighting for fire protection or suspended lighting below. Just throwing out ideas, Tim

    Roth panels would work well on both levels.
