flooring
I have linoleum flooring in the kitchen that is about ~1/2 inch raised from the floor. There is 1/4 ply and two layers of linoleum.
I'll be putting down vinyl flooring and I want to extend it to the rest of the house without a reducer.
I looked for underlayment options but the largest that I found so far is 6mm. Is there another cheap material that I can use for this? The rest of the floor space is 1000 sq ft so it has to be something cost effective.
I'd question how waterproof you need this to be. Will there routinely be water sitting on the floor? If not, you may be over-engineering things.
That said, off the top of my head, one option for waterproofing the subfloor would be to paint on Redgard:
It's a 'paint on' waterproofing membrane that you'd typically use behind tiles on cement board and the like.
Sometimes it takes a village. Here's a summary of what ended up working:
I'm now looking at fir flooring in relatively good condition, minus a nasty gouge mark I made when first trying to remove the tiling by force.
Some other details for those reading:
This, in the end, was really backbreaking work. Whether it was worth it or not will be more obvious once I figure out how well I can repair the gouge I made.
Thanks everyone for your help with this!

I doubt you'll find a soft underlayment that's that thick, 1/2". You will probably need to lay down 1/2" plywood and then add your flooring on top of that.
There are many reducer transition pieces if you should decide to keep the new floor lower than the existing one. I know you stated you don't want that but it might end up being a viable alternative.
