External thermal insulation is an insulation system installed on the exterior of a building’s walls, rather than inside the house. Essentially, the entire building envelope is “wrapped” with insulating material, preventing the walls from being directly exposed to external temperature fluctuations. The result is twofold: the building maintains a more stable indoor temperature throughout the year, with reduced need for heating or air conditioning, while at the same time the walls are protected long-term from rain, moisture, and intense sun exposure. Since the entire installation is carried out externally, the interior of the house remains unaffected — no space is lost, furniture does not need to be moved, and no work is required inside your living areas.
