As a young carpet installer, I had the opportunity to witness more than a few different management styles from the installation managers at the shop from which I received work.
Already big tile is getting even bigger! I don’t know at what point if any the term “tile” should be used when they get to be half the size of a sheet of plywood.
Heat welding seams in resilient sheet flooring or tile is one of the more specialized talents an installer can possess and is a service that a dealer or flooring contractor can offer for a virtually “seamless” floor.
