Q: I am going to install a Pergo Vintage Home Traditional Strip floor in my dining room.
I am going to use 6MM cork as an underlayment. Does the cork underlayment also require a 1/4 inch expansion space around the perimeter of the room?
Thank you
Joe
A: If you wanted to be overly cautious you could include an expansion gap for the underlayment as well, but its not necessary. Cork is great in that it really does not expand/contract very much from temperature on its own and typically only sees much of this in the engineered floating plank versions of cork.
If you want to make the installation easy, just lay down your cork flush with the walls, then install the floor with proper expansion gaps and you should be all set.
