OK, If I add something to the subfloor I can very closely match the hieght of the yet to be installed Laminate floor to the existing floor.

I plan on going with quick-step and they have these things called softboards
here is link if anyone wants to know what I am talking about
Quick-Step Softboard (http://www.floorshop.com/laminate-flooring/quick-step-laminate-flooring/installation-material/1/4in-softboard-109-sq-ft-package-/store/sku.cfm?item_id=156715)
which are 1/4 thick underlayment mainly used for sound. Then I would have to put a foam underlay on top of that. If I did this it would make the two floors about 1.5 mm difference. Which would be great, then I think I could actually use T moldings between the two floors (wood & laminate). Would that difference be small enough for a T molding??

Does this seem like a viable option or should I be using something else to raise the subfloor a little? It is plywood already, think 3/4 inch. Adding more plywood would be more trouble than its worth to me. Would have to rent a truck or something to get plywood to my place and think it would be pretty costly after everything.

Checking the quick-step web site, they actually recommend this two layer underlayment for installing on an existing wooden plank floor. So I imagine its fine, but wanted to check around to see what others think.


It has been a while I have been researching everything, should be ordering everything next week. Thanks everyone here for all the help during this time, very helpful here.
