Can I float this floor? I don't know why it lists only glue-down and staple as install methods.

They say you can't. There is a lot that goes into the manufacturing of an engineered floor so it will float. Floors that will float will have the same make-up in the top layer as the bottom layer. The bottom layer is the "balancing" layer. Probably a difference in the joinery system too.

But don't take my word for it , always follow the manufactures instructions.

No. Don't even think about trying it either.

Floorguy,
Why is it that it can't? I've been waiting for a week from a response from the manufacturer with no luck. I thought it could be floated if it was tongue & groove construction (this one is).

This is going to be a DIY project and it seems like it will be easier to float than glue - especially for a first time installer!

The T&G milling is too sloppy, to get good compression.
