Definitions
- the present invention relates to the thermal renovation of buildings and more particularly the thermal insulation from the outside (IDE).

- the insulating material is deposited in a fluid form on the facade.
- the insulating material may be deposited in an additive process, in successive layers.
- the deposited layers can be stacked vertically, or even horizontally as well. This can make it easier to vary the thickness of the insulation depending for example on the insulation to be brought locally. For example, some parts of the building are already insulated from the inside and require less external insulation.
- the fact of being able to vary the amount of insulation deposited locally to adapt it to the real need for insulation can make it possible to locally reduce the quantity of insulation required, and to reduce the quantity of total material and therefore the carbon footprint of the insulation. 'work. It is also possible to increase the amount of insulation depending on the location of thermal bridges on the facade.

- An example of an external thermal renovation method according to the invention making it possible to produce such an insulation, may comprise, as illustrated in FIG. 1, a first step 10 consisting in making a scan of the facade to be renovated.
- This scan can be performed by any suitable technical means, for example using a drone that flies in front of the facade and scanning it to record one or more images that are then processed by computer to isolate the contours of the facade and openings present on it, and identify any elements likely to disturb the installation of thermal insulation.
- the images can be taken other than by a drone, for example from the ground or a neighboring building.
- the scan can take place in the visible range and possibly in F IR to highlight local heat losses, for example to reinforce the insulation at their level.
