The Content Of The Article:

I want to isolate lost roofs. I am proposed to do this by insufflation of rockwool. Part of the attic is sloping. Will there be a settlement of the wool in the sloping part and cause the wool in the lower part?

The insulation of the attic lost by insufflation bears a relatively limited slope, because the packets of loose insulation "stand" between them. If this slope is really too great, it is necessary to replace on this zone the insulation by insufflation, by insulation in rolls or in semi-rigid panels.
