Laminate Floors over radiant heat in concrete slab
 
Hi newbie here. We just ordered laminate floors (Quick Step home collection 7mm) to go over a concrete slab with radiant heat. We are getting the top of the line Quick Step underlayment (unisound combi floor). Our house was built in 1950 and the heating system is Radiant (hot water). I know it feels hot on our feet while heating, I don't know how hot it gets. We are getting this professionally installed, and the store where we bought it, said it's fine to go over my slab with radiant. Can anyone here 100% verify if these laminates will be ok on my floors. Thanks in advance.

I only know that it is not a good way to go. You need engineered flooring over radiant floor. Also what are you doing for moisture control over the concrete floor?

Thanks Bob - I understand the underlayment has a moisture barrier layer. The laminates state they are good for radiant floors. Do you know specifics as to the problems I might encounter? Thanks.

Laminates do not have much real wood and some are rated for radiant flooring. Be sure the one you select is. The thinner laminates will warp and separate with radiant heat with most brands.

thanks again Bob - the ones I'm slated to get are 7mm and do say they are rated for radiant floors....will I be ok???

You need to make sure they lay enough room for expansion as the laminate expands significantly with radiant heat. Also, take into consideration heavy furniture that will impede the required movement of the floor. Also, 7mm is pretty thin. I would upgrade to at least a 9 or 10. Sounds like cheap flooring.

I'd agree with jaros bros... cheap floors will not work well. How strong is their warranty. Usually they say anything to sell you the product, but then if all goes wrong they blame the installation.

Warranty is 20 years

They all have warranties, but that is only as good as the company that is going to back it up and you have to read all the exclusions which is pretty much everything. 7mm is for very, very light use. I don't ever put anything that light down.
