Over-insulating?

[ows]

I have a garage with 70mm insulation in the walls. I'm thinking of improving this a bit while I'm replacing the panel.

If I add an extra 70mm, the majority of the finished wall will hang outside the slab. This doesn't feel quite right.

Is there a clever way to build to get an extra 70mm?

If I play it safe and add 45mm extra insulation, "only" half the wall is hanging in the air. Is this OK?

140 mm insulation on a garage!
I have 25 mm sawdust in my house.

Built a workshop with 120mm in the wall and 45mm insulation thickness, really good energy efficiency. There's 500mm loose fill insulation in the ceiling.

Mjo 140mm might be a bit much. But if I'm going to become a ping pong pro and need to keep it warm all winter, I want some economy in that.

At the very least, I'll add 45mm and then almost 60% of the wall is hanging in the air. Feels a bit backwards, but at the same time, we're not talking about gigantic weights/forces.

So, OK?

Yes, it's okay.
Is the eave enough just to protect the walls?

But you shouldn't have it so warm when you train pingis.
It's a very active sport, so you stay warm anyway.

Good luck with pingis! The competition is tough, right?

The roof is enough. Just built a new one.

Table tennis was just an example. In reality, we who build don't have time for anything other than building.

Thanks for the input KOW.

Is the inside of the garage covered with plastic? If it's not covered with plastic there but just a windbreaker or nothing at all, you can add insulation on the inside.

Thanks for the tip, but it is laminated. Also, I'd preferably avoid renovating electrical/surface layers inside right now.

I have 190 in the walls and 400 in the ceiling of my garage =)

Maybe a little difference in insulation needs between Västerbotten and VG...

Perhaps a slight difference in insulation needs between Västerbotten and VG...

Of course, there's a difference—have you ever heard of a ping-pong player from Västerbotten? Probably not, because they have too warm garages there.

But it's just a guess from me
