Roof insulation : the price varies depending on the surface of the roof to be covered and the insulation material chosen.

  • In Salwonia: the basic premium is € 5 / m² if the work is done by a contractor

In Blanders: the premium is 6 € / m² for works done by a contractor or 3 € / m² by doing the work yourself when you perform 3 works over 5 years.

Facade insulation : the final amount of a premium for the exterior insulation depends in part on the finish chosen (cladding, plaster, briquette or plaster).

  • In Salwonia: the basic premium is 12 € / m², and can triple according to your income
