ANyone installed laminate flooring?

[The Grizz]

I have it under my 155 BF in my living room and under a 125 & 55 in my office. And mine is doing fine, I have underfloor heating as well. Use the best underlay that you can but this is the key, whether you have underfloor heating or not use the best underlay and I would suggest at least a 1/4" subfloor just to be on the safe side. As long as the room has the proper expansion on the other 3 side's of the room it will be fine, mine is. The living room is 640 sq' and so is my office.
