After the roof, the walls are the second-largest surface through which your home loses heat. Insulating them from the outside is like wrapping the building in a continuous layer of insulation, without affecting the interior or losing a single centimeter of living space.
SDC Ecogroup provides exterior wall insulation throughout Belgium.
The principle is simple. Insulation panels are attached to the exterior of the walls and then covered with a finish that protects them from the elements. The building is completely enveloped, which eliminates thermal bridges at floor junctions and corners—the areas where heat escapes the most.
The insulation is covered with a finishing coat in the color of your choice. This is the most unobtrusive solution—the one that most closely resembles a traditional facade—and it blends well into a residential setting.
A cladding system—in the form of boards or panels—is installed over the insulation. This results in a more noticeable change in appearance and provides an opportunity to give an aging building a fresh new look.
Exterior insulation changes the appearance of the facade, and most Belgian municipalities require prior authorization. You must also take into account roof overhangs, window sills, downspouts, and the added thickness of the window frames. These points are reviewed during the technical inspection.
Everything happens outside. Your rooms retain exactly the same volume, and your interior is never affected.
The envelope is continuous, with no breaks at the floors or corners. That’s where exterior insulation makes all the difference.
The work is being done outdoors. No need to clear out any rooms, no furniture to move, and no dust in the home.
Insulation is accompanied by a new finish. The building becomes more energy-efficient and gets a new look—all as part of the same construction project.

We inspect the condition of the walls, roof overhangs, window and door frames, downspouts, and any specific structural issues affecting your building.
You will receive a proposal detailing the selected system, the chosen finish, and the work to be done, item by item, with no obligation.
The project is entrusted to one of our certified partner companies, selected based on its area of expertise and service area. SDC Ecogroup remains your single point of contact from start to finish.
In most cases, yes, because the building’s exterior appearance is altered. The rules vary from one municipality to another, and even more so in protected areas. We address this issue during the site inspection.
From the outside, if you can change the appearance of the facade, this is the most effective and least intrusive solution. From the inside, if the facade must remain as is, for regulatory or aesthetic reasons.
It depends on the surface area to be treated, the finish you choose, and the weather conditions. We will provide you with the estimated timeframe in the quote.
It is technically possible—for example, on a particularly exposed gable—but the continuity of the building envelope is precisely what makes this method effective. We’ll discuss this during the tour.
No. Everything takes place outside; you can continue to use the premises as usual.
Yes, throughout Belgium, through our network of authorized partner companies.
