The insulation is also used for heat waves in summer.
Certain also say here not serious the heating, one saves on the heating! but in summer when go cook what we all do air conditioning! Like the Americans, they eat more current in summer than winter.
A well-insulated house prevents heat from entering the house, at night you store the friache ..

You are right André.
The ideal is a house insulated from the outside and with walls having a high thermal inertia to keep the cool inside (or the adobe walls - earth + straw - as in Africa or some old houses in my region, not far towards Lyon / Roanne -the country of camel1-).
In my case, there are 20 cm of rock wool in the hollow walls without thermal bridges + red cedar cladding, and 20 cm in the roof.
The wooden frame has a drawback: no thermal inertia in the walls. I know something about it, the temperature rises slowly during the day, but it is easy to make it drop at night by making drafts (picture windows and open windows) because we are in the countryside and the temperature drops well the night. If in the future temperatures were to rise again in summer, I will consider the Canadian well.
Another important precaution: close the shutters securely where the sun "beats" strong => otherwise greenhouse effect.
In the end no need for air conditioning. In hot weather, it can go up to 25 - 27 ° C maximum. We withstood the heat waves particularly that of 2003 (15000 dead in France - mainly elderly people)
