Hi All,

I'm putting in laminate flooring in a hallway; the hallway opens up
into a room on one end. If you measure from the far end of the hallway
to the far wall of the room, it comes out to about 30.5 feet. Now, I
read on the package that if you putting the flooring in over a width or
length that exceeds 27 feet, you have to put in "expansion" molding?

Can someone enlighten me on this topic? What is expansion molding?
Additionally, I'm wondering what will happen if I just go ahead and put
it in without expansion molding? Am I likely to see problems with the
floor? Thanks for any feedback!

Sincerely,
-Josh
