If I have 10mm for shallow compartments, with wind protection/air gap delimiting thin hardboard, and I'm thinking it might be possible to compress the insulation these 10mm instead of starting to layer down the thickness of the insulation, which of the following, do you think any of the products below can be easily compressed?
-Icell boards of cellulose
-Hunton Nativo boards of wood fiber
-Isolina boards of linen

Best answer
Maybe you can feel them in the store? A hunton board is fairly solid. Of course, you can compress a 220 to 210mm, but if there is an air gap on the other side, the risk is that the air gap gets compressed and works a bit worse. If I've understood your construction correctly... maybe I'm misunderstanding you.
I haven't worked with the other boards. But glass wool and mineral wool can be compressed a bit easily.

If you absolutely feel the need to have something insulating in such a thin gap (air itself insulates, as in an insulated glass unit), then porous board could be an option. It will insulate better than compressed anything. Porous board is diffusion-open which is a smaller risk than, for example, engine compartment insulation from Feltema or condensation insulation mats like vermaculite (might remember the name wrong, do not quote me 
)

But hey, TS doesn't say that the thickness is 10 mm. TS says the insulation should be compressed by 10 mm. It's guessed that 220 mm of insulation compressed to 210 mm functions almost exactly the same as 210 mm of insulation.
However, TS should actually state how thick the board is if someone is to answer whether it's possible to compress by 10 mm...

120mm thick sheets of insulation. The thing is, I don't have a rip saw for studs that governs the depth of the compartments and I'm trying to find material that ends up with good construction dimensions when they're combined. Either there will be a bit of empty space, or I'll need to compress the insulation by 10mm, and it should be an open construction so that moisture can pass through, so mineral wool is not an option. It's 10 miles to the hardware store, so there's no time to go and feel the materials.
Can't you add 10mm to the rule then? For example, with a suitable construction board.
Problem solved, found läkt in a format that provides a 120mm deep compartment perfectly
