There are a few old threads on here talking about mixing go board and kerdi pans, I just wanted to know if this is still a viable option instead of using durock/kerdi foamboard? I've been getting mixed answers everywhere else and only on this forum people seem to have used the combo without reservation. Thanks.
Goboard and kerdi?

It would be way overkill but you could. Definitely do a flood test no matter what. You have to trust the fabric. It will bond to the GoBoard with thinset just like any other surface.

That’s a lot of layers using 1/2”
It's a 2 wall shower so one curb will need to be 60"and the other about 45". I would need 3 kerdi curbs and at 60 bucks a pop I figured I could do a thin curb with the goboard, obviously still at the correct height.
Either I can build them box style like someone mentioned or just lay flat sheets. I haven't got the schluter pan in yet so I'll need to wait for that and measure height to figure out my exact cost.
If you’re doing glass on the curbs do not do a 2x4 wrap. There is a risk of water penetration when they install the glass channel if they use screws.

Will definitely not be going with a 2x4 wrap. With the foam curbs though they will either have to use silicone only or drill just the tile.
Most drill them. That’s what does in the wrapped curb. If it is a foam curb, unless they drill all the way through it the holes don’t matter.
If you can get the glass thickness, Schluter makes a channel for glass you install as you tile.

I will look into that, thanks. Drilling the curb is the reason I was thinking if it's possible to fill to fill it with something like great stuff foam or equivalent.

Get a sheet of 2” thick kerdi board.
This is the channel you're talking about, correct?

All I install is a hybrid system. Kerdi pan and DensShield Walls. The Denshield is installed with caulk between the seams and then banded with FibaFuse and topical (Mapei AuqaDefense is my goto).
Kerdi will bond to just about anything tile will since it's bonded with thinset. So you know it will bond to the Kerdi and since all tile substrates are designed to bond to thinset...you see where I am going.
Never build a curb out of wood. It expands and contracts and moves way too much. Can't tell you how many wood curbs I have ripped out. Used concrete blocks, foam or mud with a quickpitch type form.
