Have a seasonal home in upstate NY in the adirondecks. Home is built on a concrete slab. Ground level consists of kitchen,dining area, bathroom & livingroom, with concrete floors. We have put a concrete sealer made by UGL Dry Loc.We have no water problems.Home is insulated well, however, in the winter we have NO heat. We do NOT have the height to install wood floors because we would need nailers, then plywood, etc. We like the lamimates, however lumber liquidators DOES NOT have a floor that will warranity it below 55 degrees. We want to install 6mm plastic, then the more expensive vapor barrier, the one that they recommend is the $50 a roll for 100 sq ft. That will cushion the floor, help humidity, mold, & cushion & give the floor a R-value. Lowe's has a Pergo 35 year warrinty that i hear will not have a problem in the cold, good for a seasonal home??? Any suggestions??? The interior walls are all knotty pine, all done brand new over the last 2-3 years.We do not want carpet, lino or tile. Lumber liquidators said if we were going to go with a laminate, go with at least a 7mm floor without the backing on it, so we could use the better vapor barrier. Anyone out there ever put a laminate floor down on a GROUND level home on CONCRETE & just floated the floor??? We want to use the click floor, NO glue! And also put it in a vacation home where no heat was to be on during the cold winter months????
