Title: layers under elements
Post by: chris on April 03, 2008, 06:33:16 PM
I am putting warmfloor in my daylight basement in Montana.  80023 is the project number for Ductmasters.   

Will there be any problem with putting a plastic sheeting vapor barrier, 1/2" of extruded polystyrene with 1/4 of particle board under the elements? 

We will be carpeting over it, and the warmfloor is supplemental heat for the basement. 

The other thought i had was doing thin set mortar over the top of the elements, but i am afraid this will make the floor feel hard.

The diagrams show putting the insulating and element layers together, but i read in another post that putting the elements on a plywood layer is ok.

If i left anything out please let me know,

chris

Provided it's all put together correctly, that preperation may be ideal.  And I'd pass on the thinset unless you're using it to set tile in.  Frankly, I'd recommend you consult a local carpenter who could look at your basement and make recomendations that way.
