Due to the manufacturer's requirements we must follow their guidelines to uphold our installation warranty. If you have questions about the requirements of the flooring you have chosen at the store, ask your flooring Specialist at Lowe's about the transitions needed. That information should also be in the box with the installation instructions if you would like to read it. You can trust that we know all the requirements and follow them so you get the best result possible! As a part of the measurement we do for you, we will send a diagram to Lowe's that shows the layout of the rooms we will be installing in and where transitions will be used. They should review this with you before you purchase.
