PermaStone in a 3 season room
We have been researching flooring for our new 3 season room (in St Louis)and had almost finalized our decision to use NAFCO PermaStone tile when a flooring store told us that we should not use it in a 3 season room. He told us that the warranty would not be valid because the room will not be climate controlled.
The room is on a raised deck floor and we are having the floor insulated and a shed will be built under it.
The flooring store told us that the ONLY flooring that would be warranteed would be carpet (glued down) or porcelain. Neither of these are my preference.
I also inquired about VCT, rolled vinyl, rubber, and bamboo but he said NO to all of those as well.
Does anyone have any other suggestions or any experience with using composite tile in a 3 season room?
