radiant over concrete and under laminate flooring

I looked at a job last year that had a pergo type floor installed over radiant. If I remember correctly it was running around 150, and the floor was ruined. You could see each line under the floor.

The high temperatures were a result of bad (no ) design, insulation details in the home, and a contractor who never returned to balance things. I'm not sure what temperature ruined the floor, do some serious research. The job I looked at looked as if a lower temperature, longer cycle might have heated the space just as well.

    I have a client

    who wants to install radiant of the basement floor and install laminate flooring over it.

    Any wallies done something similiar to this?

    If so what are some recommendations for applying the radiant to the floor or do you use the combo wood/aluminum plate panels?
  • Best way

    We used to use Stadler Climate Panel and then went to Uponor Quik Trak:

    Read over their instructions for your particular application; they may want some plywood between the concrete and the Quik Trak.

    Also look at

    The Roth panel system. It is foam product with aluminum over the entire surface. Foam adhesive will fasten it to the concrete if it is clean.

    The 2X4 foot panels are grooved for the pex to snap in.

    Use PAP tube for less expansion and contraction.

    Then float the flooring over the panels.

    Why mess with the floor??

    If you're looking for simple radiant comfort, look up...

    Here's the ceiling of the kitchen/dining room at Hydronicahh.

    It's not so much a case of "You got what you paid for", as it is a matter of "You DIDN'T get what you DIDN'T pay for, and you're NOT going to get what you thought you were in the way of comfort". Borrowed from Heatboy.

    Basement subfloor

    I've used this before and works great, along with the Quik-Trak

    Why lose the headroom?

    Install Viega's climate panel on the lower half of the basement walls. Assembled Climate panel is 42" wide. cover it, put a trim over the top edge....presto! Looks like a chair runner.

    the system

    I did had 3/4" nail down WALNUT! flooring attached. It was cut and milled at the owners farm in Arkansas. The Roth Panel was glued and stapled over a wood framed floor so nail down was possible.

    I like the Roth over concrete (glue down) as it gives you some r-value and a bit of softness to the floor. The foam/ aluminum is very easy to router custom grooves into, also.

    For flooring options contact www.launenstein.com They have a lot of info about flooring over radiant, especially floating floors. Junkers is another top of the line floating hardwood product.

    Walls and ceilings are a good option, but from my experience warm floors to heat a space are still the very best. Installation challanges would be the reason to look at those other options.
