What precautions should you take to install such insulation outside the home? How to prepare the ground? What about the connection with the foundation wall?
Because I saw that the Bellouate® was made from recycled newspapers (see the Afnor standard => unsold dailies, according to what they say) if this is the case, put it outside, even with a breathable plaster + plaster ... it is quite harsh conditions ... especially in very humid regions with high rainfall.
We realize this type of insulation when the technical conditions lend themselves to it (house on one level, easy access in foot of walls, etc ...) otherwise the constraints of use of the wadding are too important (in wet projection , because we do not blow under pressure in vertical) and it becomes more interesting economically (but not necessarily technically ...) to use wood wool panels.
So when it is possible, we realize a framework (in 2 thicknesses crossed most often) which makes it possible to create the place for the wet projection of wadding (often on 120 mm).
The feet of walls are treated with expanded cork, which is buried to cut the thermal bridge of the slab. The wadding is always more than 30 cm from the ground.
Above the planed wadding, one installs either the HPV + slats + cladding or Fibralith + breathable coating, according to the customer's choice for its exterior cladding.
All wadding is made from unsold newspapers (and a very small percentage of recycled newspapers with very strict criteria).
There is no problem using it outdoors, as soon as the rainscreen is properly put in place. Cellulose wadding does not store moisture, it exchanges with the outside environment, hence the importance of choosing the correct HPV rain protection.
You have to get out of the logic of "all synthetic, all mineral, all concrete"and that you open up to natural, high-performance and durable products that have an infinitely lower environmental impact than all the products you have been taught to use during your professional life.
