Proper material to raise a subfloor....

Alan

My house has been remodeled several times it looks like, as there are three layers of 3/4" ply under the linoleum where the new remodel butts up to the laundry room. After putting a layer of t/g subflooring down, I still have 1-1/2 inches of space to make up to the finished surface. Do I need to buy more T/G flooring material or can I use something else? Should my final layer be something different if I want to continue linoleum into the new area?

That's a lot of subflooring but assuming you're correct, why not add 2 layers of 3/4" ply? Otherwise you could just add a threshold.

Only thing I can think of is for you to install a 3/4" Wood stock at about 12" OC. Then install another layer of 3/4" T&G Floor sheathing over it.

Lock all down tight with construction adhesives. I pity anyone that has to remove all those layers in the future (for whatever reason...)

The thing that would have been better (too late now), would have been to install 2x4's on the flat (1-1/2" thickness) and then install your T&G 3/4" Floor sheathing over that...Essentially, I am proposing the same concept to build the floor up now.
