Alternative to drywall for skylight tunnel?
Gentlemen,
I'm going to be installing a skylight in a bathroom this week. Insulate it as much as you can, these things always have condensation up around the skylight. (Cold climate area) So I was thinking about an alternative to greenboard for drywalling the tunnel. Something impervious. Like concrete board, but not concrete board because of the weight. Like Hardibacker, but not Hardibacker because of the pattern on the face.
Anyone used something that worked well?
Thanks.

Edai plywood. It has a smooth surface and is moisture resistant. Home depot and Lowe's sell it.

Nope good paint and it will look like drywall/plaster when painted. A little skimming helps if you use cheap paint or you can't paint

How high are the ceilings? The hardi has a bit of texture to it but a couple coats of paint should smooth it out enough to where you could not see it from the floor.

Nine foot ceiling; 5/12 roof; top of the tunnel will be ~13 ft high. West facing opening so soft evening light, and broadly tapered tunnel, so glancing sunlight on the surface - hopefully everything in my favour to make up for my painting ability.

I don't know if you get this in the U.S. here in Germany you could buy a silicia-based board from the LEX Lindner Group. Easy to go almost like gypsum boards, but it's water proof.

Georgia-Pacific DensShield Tile Backer, or DensGold. Both skim well.
