CARCASS WORK:
- Insulation 
The insulation of a building reduces the heat transfer between the building and the outside environment, and thus reduce the need for heating and, if necessary, cooling. This insulation must be thought of in terms of climatic constraints on where the building is located. Thermal insulation is the basic principle of the passive house. It traps heat inside in winter and keeps the house cool in summer.
The fight against energy waste passes through thermal insulation of heated buildings. In many countries, it is the subject of regulations.
