Core side towards or away from wall? Tongue and groove board

[Tina A Västerås]

Hello! Should the core side face the wall or the room when installing raw wood paneling on an indoor wall? Thanks.

Tongue and groove boards are often made so that you have a gap on one side at the joint, so maybe that's what determines it?

It depends on whether you want the planed or the sawn side facing the room.
I would think it's a bit hit or miss which side is planed.

Depends on what is to be done on the outside, plasterboard, paint, stain, untreated, etc., but also how the råspont is sawn/planed. The result of what is called råspont differs from sawmill/planing mill in surface texture depending on the machinery. So the question is not according to me "core side".
