Hello!
A while ago, I tried a thermography equipment at home in my villa from 1964. A clear conclusion from that investigation was that it's cold in the wall/ceiling angle. An idea I got then is that the heat economy might be relatively easily improved by placing a “crown” of, for example, rock wool along the sides of the house up in the attic. An attic otherwise insulated with wood shavings. Good idea, too risky for the house's well-being, or no noticeable difference at all?
It's important to remember that most likely there is no intended vapor barrier to speak of on the warm side of the house. Additional insulation measures in the attic may potentially make it colder up there, thereby increasing the general risk of condensation in the attic. This could lead to issues with moisture and mold in the long run. So, what do you think simply
?
Best regards!

It will always be colder at the wall/ceiling connection. If you mean covering the sawdust with insulation so it blocks the air gap, that's probably not a good idea. And just replacing a small part of the sawdust with insulation doesn't seem like a great idea either.
I think it's relatively safe to insulate the entire attic as long as you don't add too much insulation and you use hygroscopic insulation. A bit of condensation and mold spots aren't the end of the world; you almost never avoid them with modern insulated attics.
It's important to have negative pressure in the house; natural ventilation usually doesn't work, so mechanical exhaust is needed.
