lar to the plywood you have just installed. Depending on the thick- ness of the tile and underlayment there could be height differences between adjoining floor surfaces. These are somewhat common in older homes and can be handled with wood, stone, or even metal transitions. I hope this helps. – Robb Roderick, NTCA Technical Trainer/Presenter And here’s an excerpt from the question that prompted the answer about plank porcelain tile and expansion joints (correct answer follows): –––––––––––––––––––– QUESTION Wow. Just wow. There’s no way to make an expansion joint [with a long plank] look right. Zero chance. And I guarantee you 99% of every run over 25’ has no expansion joint filled with flex- ible sealant. I would love to see some installs from certified con- tractors who utilize them, if for no other reason than to generate ideas for placement and to show a customer what it will be like... Fortunately, most homes do not have that expanse because they’re doing single rooms or less than the whole house. It’s really only whole homes that are probably affected, so it’s a smaller subset. But manufacturers keep mak- ing [planks] longer and longer, and they know the requirements.
