If your wood floor is the same height as Avaire tile, butting directly to the two floors will look beautiful. Avaire tile and wood flooring expand and contract at different rates, so a bead of flexible caulk should be placed in the space between the two floors.
If the wood floor is a different height than Avaire tile a reducer molding will need to be installed to transition the two floor heights.
Jonathan is correct, a t-molding or an overlapping reducer will eliminate the need for caulk and adhesive at the transition.
