Insulation - Building

Insulation is one of the main ways to sustainably improve a building's energy performance. By limiting heat loss, it reduces heating and cooling needs while improving occupant comfort.

Powesco implements solutions tailored to your property: triple insulation, external thermal insulation (ETI) and treatment of specific points, in order to address the main sources of energy loss.

  • Triple insulation — attics, ground floors and thermal insulation: up to 30% savings on heating.
  • External Thermal Insulation (ETI) — improvement of the thermal performance of the building envelope.
  • Isolation of singular points — treatment of losses on networks.
  • Thermal diagnosis, work plan and available financial assistance.

What insulation provides

  • 30–60 %

    of combined savings

  • Up to 30%

    heating savings

  • ~15 %

Good insulation reduces heat loss and helps maintain a cool temperature throughout the year, thus decreasing the need for heating and air conditioning systems and significantly lowering energy costs. It also stabilizes the indoor temperature, preventing sudden and uncomfortable fluctuations for the occupants.
