Why choose external thermal insulation?
ITE involves wrapping the building in a continuous insulating layer, covered with a coating, cladding, or finish. This technique applies to both renovation and construction, on single-family homes, buildings, or apartments.
Superior thermal performance
Unlike ITI, ITE eliminates all thermal bridges (at the level of floors, corners, junctions), ensuring continuous and homogeneous insulation. It significantly helps reduce heat loss and stabilize the indoor temperature.
No impact on living space
Since insulation is done externally, ITE preserves 100% of the interior space. It is an ideal solution for small rooms or homes where space is precious.
Aesthetic enhancement of the facade
ITE allows you to deeply renovate the appearance of your facade. You can choose from many finishes: colored coating, plaster, wood cladding, composite panels, bricks… The result is modern, clean, and durable.
External insulation techniques
The choice of method depends on the nature of the substrate (brick, concrete, stone...), your aesthetic preferences, and the available budget. All offer very good thermal performance if implemented correctly.
Is ITE eligible for renovation grants in Belgium?
Yes, external wall insulation is one of the most subsidized works under regional energy renovation policies.
- Thermal resistance R ≥ 3.7 m²K/W
- Carried out by a certified professional
- Compliance with regional technical standards
- Integration into a comprehensive renovation project
- Wallonia: Housing Grant (up to 45 €/m² depending on income and performance)
- Brussels: Renovation Grant (up to 60 €/m² depending on PEB category)
- Flanders: Mijn Verbouwpremie (variable amount depending on income)
We assist you from technical estimation to compiling the complete file, with material sheets, certificates, and administrative documents.
What is the price for external wall insulation in Belgium?
The cost of an ITE is higher than that of interior insulation, but it is offset by its lasting performance, the aesthetic of the refurbished facade, and eligibility for energy bonuses.
Factors that influence the price
- Type of insulation
- Installation technique (rendering, cladding, integrated panel)
- Height of the building (scaffolding)
- Condition of the facade (cleaning, prior repairs)
- Finishes (classic render, decorative, high-end wood cladding)
- Additional work (gutters, thresholds, window sills...)
Indicative prices in Belgium
| Type of ITE | Average price including tax per m² (installation included) |
| ITE under coating with EPS | 100 to 130 € / m² |
| ITE under coating with rock wool | 120 to 150 € / m² |
| ITE with wood or composite cladding | 150 to 200 € / m² |
| Integrated decorative insulating panels | 130 to 170 € / m² |
| Preparatory facade work | 10 to 25 € / m² |
| End of site: supports, finishes, zinc work | 20 to 50 € / m² |

Which insulators to use for effective external insulation?
The choice of insulating material has a direct impact on thermal resistance, durability, and the aesthetic appearance of your facade.
- Expanded polystyrene (EPS): lightweight, economical, widely used under render
- Rock wool / glass wool: excellent thermal and acoustic performance, fire resistant
- Wood fiber: natural insulator, good moisture regulation, good thermal lag in summer
- Polyurethane (PUR): high thermal performance for low thickness
We select certified materials, compliant with European standards, with thermal resistance R ≥ 3.7 m²K/W, required for regional grants.

FAQ – External wall insulation (EWI) and energy renovation in Belgium
Is EWI more effective than internal insulation (II)?
Yes. External insulation allows for the elimination of thermal bridges (floors, wall junctions, lintels) and completely envelops the building. It offers a better continuity of insulation, resulting in higher thermal performance, improved comfort, and a greater reduction in heat loss.
Can we benefit from grants for EWI in Belgium?
Absolutely. EWI is eligible for the main energy renovation aids in the three Regions:
- Housing Grant in Wallonia
- Renovation Grant in Brussels
- Mijn Verbouwpremie in Flanders
These grants depend on criteria such as:
- The insulation coefficient (R ≥ 3.7 m²K/W)
- The insulated area
- The household income
- The overall energy performance level
Our teams assist you in obtaining maximum subsidies.
Which insulator to choose for EWI in energy renovation?
The choice depends on your priorities.
- EPS (expanded polystyrene): very common, economical, good for renders.
- Rock wool: excellent thermal + acoustic insulation, fire resistant.
- Wood fiber: ecological, effective in winter and summer, breathable.
- Polyurethane (PUR): very high insulating power, ideal when thickness needs to be limited.
We help you select the certified insulator that best suits your facade and project.
Does EWI change the appearance of the house?
Yes, and this is a major advantage: it allows you to refresh or completely transform the facade with a modern, natural, or traditional look depending on the chosen finish (render, plaster, wood cladding, decorative panels...). EWI is both an energy gain and an exterior makeover.
Can we insulate only certain facades from the outside?
It is possible, especially on non-adjoining facades. However, to achieve optimal thermal performance and maximize grants, it is advisable to insulate all exterior walls. A technical on-site assessment allows us to determine priority areas, while adapting to your budget.
