For a house in Aix-en-Provence, what are the best solutions to isolate the best under tiles, on the ground (attic 80 m lost2) and two concrete walls supporting the roof?

For attics, there is no need to isolate both on the ground and under cover crawlers. It is possible to just blow about thirty centimeters of loose insulation on the floor. Cellulose wadding benefits from a better phase shift (heat transmission time), which leads to favoring it in hot regions (less overheating in summer). For the walls, the ideal would be to make an insulation by the outside (ITE) to avoid overheating of the blocks. Different solutions are possible, again with cellulose wadding or with polystyrene and coated.
