Rubber strip or some kind of sealant?

[brinckis]

I am decorating my garage and put up horizontal paneling on an interior wall yesterday. Behind it, I have 45 insulation / plastic / 120 insulation, etc. I decided to leave the panel a thickness, i.e., 22 mm from the floor, but discovered only after it was mounted (as a hobby carpenter) that the insulation is visible at the bottom. I hadn't thought of this before. Now I would like to "seal" the "gap," and my first thought was some kind of silicone sealant. But 22 mm is quite high, maybe a rubber strip? Does anyone have any suggestions? It shouldn't cost a fortune either, as it's about 30 meters of wall.

Not so many tips but I think I've figured out how I should do it anyway. Flip up a batten behind the panel and attach it with brads. This way, the insulation won't be visible. Cheap solution too.

Good!

If it's just because you don't want to see the insulation, perhaps expanding window tape might work?

If it's just to keep the insulation out of sight, perhaps expanding window foam seal could work?

Good idea. I'll take it with me, it could be a solution.
