insulation, a weapon to fight against heat waves

For the construction of their house five years ago, in Chessy (Seine-et-Marne), Vincent Deneuville and his wife Marie-Odile had one priority: insulation. With the repeated heat waves, they do not regret their choice. They gain more than 6°C thanks to optimal insulation. For this, they installed 22 cm of insulation on the roof, as well as for the walls. They also placed an insulating slab on the floor, as well as an airlock at the entrance to prevent hot air from entering the house.

No radiator, no air conditioning in this house, which is called a passive house. The additional cost is 10% to 20% compared to a conventional construction. However, these additional costs quickly pay for themselves. “In electricity, we are at around 100 euros per month, all inclusive”, believes Vincent Deneuville. However, this technique is difficult to implement everywhere, because it takes up space, which is not suitable for housing with smaller surfaces.
