Thanks for the information! I am concerned about the integrity of foam as a subfloor but I am sure that I read about its use somewhere. As to the use of the laminate in the kitchen and bath, Pergo says it can be used there so long as the expansion perimiter is sealed with silicone or, surprise, surprise, their product. Would their warranty not cover this application?
PS: Do you recommend an alternative (not carpet) to this application?
