Yes apparently but we are not going to make cheese out of it, eh!

I am in the process of making an apartment and I was wondering about the insulation of the walls, I saw wood wool which seems to me an excellent product but the price seems a bit high to me 12 euros per m2 in 100mm at me plus the port.
I therefore thought to use behind the plasterboard either slices of straw bale or loose wood chips I could in my case easily make partitions higher than the walls (about 50cm of lost attic) to solve the problem of the settling of the chips .
What do you think?

I did not really understand your history of wood chips ...
Otherwise, I'm using wood wool, and I think it's okay.
The installation is not problematic, no scratching etc ... and the lambda is 0; 036 (actis from L **** M ****)
On the other hand, it is true that it is not given as insulator. I'm not even talking about the price of panels in 140 see more ...

Well that depends on what you compare.
If it's to replace glass wool (loose insulation), yes it's more expensive.
If it is to replace expanded polystyrene (panel insulation), then wood panels are of an equivalent price or even cheaper!
The thickness does not matter on the price. It is the price per m3 that counts.
If actis distributes at LM I think it will be a great commercial success this product ... I would think of asking them for my commission in kind the next time I need insulation!

I would like to share a little feedback.
I insulated a ba13 wall from behind with 100mm wood wool.
For that I had to make an access hatch that I made myself and insulated in 80mm extruded ps.
I carried out measurements, the surface insulated with wood wool is around 13 ° c and the trap door with the extruded pextruded is at + 15 ° c.
I thought that the wood wool would have as much to see better insulated than the pse part ...: - /
I have the same phenomenon with another hatch.

The Lambda coefficient of wood wool = 0.04
that of pse = 0.03
==> R wood wool 0.10 / 0.04 = 2.5
R pse 0.08 / 0.03 = 2.67
Pse advantage
BUT for cold only ...
Ldb advantage for heat and noise level.
For the price it all depends on the supplier and the discounts.
Everyone's choices

Sometimes it is better to stop, reflect, and ask the right questions ...
Back to "Heating, insulation, ventilation, VMC, cooling ..."
