Bamboo Floating Floor in a Hallway.

Q: I am planning on installing your bamboo in my hallway it is 60 feet long. I am planning on floating the floor. what is the maximum length that the re-engineered floor can go with out a joint? I would like to install the wood parallel to the long wall but I am afraid that 60′ is to long.
A: Depending on the specific floor you are looking at, but my guess here is either Springwood’s engineered line or Ming Dynasty’s handscraped or strand woven engineered lines, will depend on how far the floor should go. The technical answer is that a floor can extend for the full distance of your hallway so long as you allow for the proper expansion gap along the edges of the floor. There is a fairly simply formula to determine how large an expansion gap you will need. For every 27 inches wide of your floor, you will need 1/16″ for expansion. This means that a floor which is 12 feet wide would need an expansion gap of about 11/32″ around the edges of the floor.
Basically put if you allow for a 1/2″ expansion gap along the edge of your flooring in the hallway you should be fine. The problem will occur in any doorways. Make sure you use a proper transition piece in doorways and allow for a proper expansion gap otherwise you could encounter expansion problems around your doors which will slowly spread along the remainder of the hallway.
I would also heavily suggest giving the floor plenty of acclimation time. Also make sure that the environment in the home remains roughly the same all year round. This will remove worries of shifts in the floor due to climate change.
