Does the laminate flooring have to be a certain thickness to allow radiant heating to work properly? Can underlayment (moisture/sound barrier) still be used?

Check the flooring r-value before installing. As long as the flooring product has an r-value of 1 or less, it should work well with electric floor heating. We suggest the underlayment be placed under the heating layer. The heating element should be placed between the underlayment (preferably at least 1/4") and the flooring.
