We're pulling out the carpet in a room next to a room with hardwood floors. After removing the carpet and putting down the engineered floor, we'll be 1/4" short of the hardwood.
Use transition strips for the 1/4" difference
Put down 1/4 ply on top of the current subfloor
And then I thought of a 3rd option:
- Put down 1/4" Extruded polystyrene (XPS) panels.
The XPS seems intriguing for a couple of reasons:
- While not a lot of insulation, it wouldn't hurt
- It may cut down on the 'hollow' sound that engineered floors sometimes produce
- It'd do double duty and act as the underlayment (vs rosin or tar paper)
Thoughts on that? Is that a good idea? Any cons that I'm not thinking of?
Per Eric's suggestion, I finally called them and got a vague answer that was basically "you can put it on most anything that is flat provided it doesn't have any give". They felt the XPS might have too much give and stress the joints.
So, I suppose that is the question, how much give DOES XPS have? I've walked on XPS boards with shoes plenty of times (I'm over 200lbs) and didn't leave a mark, so itis a material that seems to have fairly decent compression resistance provided the load is spread a bit, and it seems that the flooring would certainly help spread the load more than my shoe would.
