I have an older home with carpet over concrete floors and hot water radiant heat. I live in the mid-atlantic area (central Virginia) so we do get some fairly cold weather at times. I want to replace my carpet with a laminate. I talked with some manufacturers about this and they say it's an excellent choice but not to exceed 85 degrees on the installed floor. My boiler is set around 125 and so it would seem to me that there would be spots that would exceed the 85 degree max. Is this max temp rating of the flooring concerned with expansion or possibly scorching? Should I be more concerned about the average temp of the floor? Can I offset the difference in operating temps by altering the 1/4 minimum gap around the perimeter? I really want to do this project but conversely don't want to ruin the product. Are there any flooring contractors out there that could comment? Thanks in advance!!!
