Do you need to run Ditra right to the edge of the room? Thinking of leaving a gap to deal with a high perimeter.

I've got a room with a two-layer plywood subfloor that is fairly flat (not level) but the floor ramps up at the perimeter fairly sharply. I'm going to be using Ditra for the installation (only for uncoupling - not worried about waterproofing). Rather than trying to raise the entire floor to the level of the perimeter, I was thinking of just leaving an 8" gap around the edge where I would not lay down any Ditra. Anyone tried this before?

Run for your life. Why on earth would you take a job on thats on two layers of ply PLUS the outer area is raised so much that you can't get it level?

I don't want to run away from my own home 😉

Two layer of ply is pretty typical.
