Expand and elucidate more clearly, with pictures illustrating your issue.

Sophie- could you expand more clearly on the word elucidate? ;) Not all of us have studied the dictionary;)

Going to need a bit more to go on. Are you talking about LV"T" (Luxury Vinyl Tile)?

No. Luxury vinyl flooring (planks). Specifically, Mannington. Installer said that flooring cannot run the length of the room without a transition piece in the middle of the room. Can this be true? Thanks for the reply.

Mannington has specific "run" lengths. The installation instructions have specific information. Each type of floor has maximums. Without more specific information (like the product information and your specific information on the run-length) there is nothing more we can offer other than "Yes. It happens."

uh-oh. Mannington Ashford walnut. 4 ft. lengths. 5" wide. 4mm. Glue down. 30 foot run.

Does this help? I see installer tomorrow.

Thanks, again!

You just answered your own question: "30 foot run". That is the MAXIMUM run the floor can be installed WITHOUT using a transition strip. If you have a 42ft run...that means you need a transition strip somewhere (you can choose the spot so long as BOTH sides are less than 30ft).

I find it interesting that the "glue down" version of vinyl has the 30ft limitation normally reserved for "floating floor". I've read the Mannington Adura glue down and floating floor installation packets...neither one mentions a maximum "run" of 30 ft. Must be printed on materials shipped with the flooring.

Thank you so much, Cancork Floor Inc.! I will check this out when my installer comes back. You are an asset to this site ----unlike some others.
