70-year-old concrete floor radiant heat refurbish
I’m in climate zone 6A. I will be removing the 70 year old copper radiant heating pipes in my whole downstairs cement floor. The floor is considered a basement floor, limestone walls(some wood covered), built into the side of a ledgerock bank. One side being ground level. I have to do this 1200 square foot project as economically as possible. We are not quite certain how much further past 4 inches we are able to go as of yet. Our plan is to remove the inside cement floors, remove the copper pipes, lay some gravel to level, put down the NOFP Barrier x5, lay wire mesh sheets over it, then tie the pex tubing to the mesh and hand trowel poured cement over top of that. Will this be sufficient as a new heating system? There are some moisture issues due to the current cement having no moisture barrier. I cannot afford to take down the existing woodwork along much of the wall space. We are going to cut inside the walls so as not to damage them.
Any suggestions as too the correct materials for a moisture vapor barrier and the correct steps to do so while remaining on a very tight budget without reducing quality?
