Default Underlayment

Which is better underlayment?
I am installing underlayment over the particleboard subfloor. Then Quietwarmth pad and the tile in Kitchen application.
Should I use Cementboard or plywood/OSB?
I would prefer 1/4" underlayment height, but wonder if it would be stiff enough and can go up to 1/2".

All three underlayments would be fine, but first lets see if you need underlayment to begin with.

Installing Avaire tile over 3/4"particle board is okay and installing additional layers of underlayment can cause height issues at transtions and appliances.

Let me know if you have any particular structural concerns so I can suggest the best underlayment for your project.

I am removing;
2/16th Vinyl
1/16th Vinyl
2/16th underlayment
1/16th Vinyl
8/16th Plywood underlayment
----
14/16th total (pretty close estimate)

So I have 14/16 or so to work with and the current (before removing any of the existing flooring) height of appliances, doors and transitions are all okay. I would like to go back with about the same height or a little less.

If I go back with 1/4" underlayment the Quietwarmth pad and Avaire tile I should put me pretty close heightwise.
The original joist and subfloor do seem structurally sound, although I have not exposed all of it yet.

Thanks for your help Chris!

Unless there is some water damage the particle board should be fine.

Do me a favor and check the size and spacing of the floor joists,2x10 joists 16" on center are ideal. If possible confirm that the particle board is 3/4" thick. if not check to see if there is an additional layer of plywood under the particle board.

If every thing checks out, using 1/4" underlayment will be perfect, OSB will cost the least.

let me know about the framing. Also if you have questions about Quietwarmth I might be able to help. I just finished a few jobs with it and it worked out great.

The joist are 2" x 10"s that are 16" on center, and the particleboard subfloor is 3/4" which looks like it is glued and nailed to the joist.

No questions on the Quietwarmth yet, I am mostly concerned about running the conduit and wires to the thermostat and I am thinking about getting an electriction to run a new electrical circuit and make that connection.

Sounds like you're in great shape.

1/4" underlayment,quietwarth(1/8")and Avaire tile(9/16") should get you where you need.

Good call on the electrition, I use one for the final connetion on every heated floor I do.

Good luck, let me know how it turns out.
