I'm in a pickle - I installed acoustic cork on concrete slab as an underlayment. Over that is planned a radiant(mat) heater from warmly yours and then nice porcelain tile.
Problem is - tile guy is EXTREMELY concerned the cork will cause the thinset/grout to pop up over time.
The cork was put in to force more heat to the tiles vs. the concrete slab. Now I'm debating on whether I should tear out the cork before putting in the heater.
Has anyone worked with acoustic cork 1/4" thick and installed tile over it? Thoughts?

- Cork Underlayment w/Tile and Radiant heater???
Not sure myself on that one Dave. Try contacting someone at the Tile Council of North America www.tileusa.com and see if they will have an answer. They test a lot of materials and have a good handle on what works well with what.
What did you end up doing about the tile floor. I am also considering putting in cork underlayment and would like to know what has happened since you posted in 2005 about your floor at bobvila.com
