Yes, I am aware of it, but I do not think to apply it myself and to appeal to a specialized company, .... if I find one!
Does anyone know of a company of this type.
Do not exaggerate anyway ... The one that is sold in sprays in DIY stores, does not have the same coefs as that used in the building industry ...
By drilling holes in the partition, it allows to evacuate the overflow of pressure, there is nothing else to do than go easy in the filling, to let it swell in height epicetou.
Calling a pro in this case will not save you from a pressure problem against a wall. Worse, if the employee who does the job is a poacher or the boss is self-proclaimed insulation specialist ... it may well be that you can not turn against them in the event of improper application (unless take your precautions by coating it black on white ...) and in the worst case, that it is necessary to redo the wall because their products are more powerful than those found in mass distribution ...

nb: vermiculite has the advantage of not being safe for rats or others because if it engages in the layer, they drown
installed for over twenty years, never had problems
I've been reading this here several times already ... but where did you see that vermiculite was a "thermal insulator", to put between partitions ....? And how would this material prevent air from circulating because moreover if it circulates, that proves that it is not "isolated ..."
It is used as:
- high temperature heat shield.
- refractory material.
It is however simple to know it, if it is not very light, it is not a good insulator ...
