So we're going to replace the vinyl sheet flooring in our entry hall. It's about 160 sq. feet total. We were originally thinking ceramic tile, but now we're contemplating using the foamy glueless vinyl sheet from Tarkett. We found a pattern we can live with (it has some relief to it, which is nice), and it seems really easy to install...almost too easy. Besides being a 10-15 year product (although it has a "lifetime warranty"), what should I watch out for, when comparing to a traditional glue-down vinyl floor? Thanks much!
