Is there a proper way to prepare a room with radiant heat in the floor for Columbia classic clic flooring? Our floor was laid in mid october before any heat was turned on(new construction). Now we are noticing the ends are peaking and there are some sections where the floor isn't lying tight against the subfloor. At other locations there are seams or end joints that are seperating
The subfloor is advantec, on top of a 2" concrete slab, vapor barrier,and another layer of advantec flooring.

Thank you for any guidance

Since the last post, the floor had to be replaced because of moisture damage. Neither the contractor that laid the floor or the general contractor would take the blame, saying it was somebody elses fault, thus we ended up paying for most of it. Just was tired of the hassel. Turns out moisture was trapped between the layers(concrete, subfloor, moisture barrier). Radiant heat should have been turned on before floor was laid, but it was not. Manufacturer of the gypsum product that was used for the concrete layer wondered why there was two layers of advantec plywood sandwiching the concrete, so long story short, sombody jumped the gun and was told the floor was ready for finish layer, when in fact the heat should have been brought up slowly to drive out moisture.  :x
