Radiant heat

So I’m installing radiant heat under the subfloor between the joist, with the uponor joist track system. My question is, there will be tile floor above and I wanted to use the schluter ditra as an uncoupling membrane, however someone told me that it would block the heat from the floor. I haven’t read anything to this affect but also don’t want to find out after it is all installed. Please advise. Thanks again for all your help.

Ditra doesn't have a significant R-value, so you will be fine.
