Why insulate your home in Luxembourg?
Insulation plays a crucial role in the comfort and durability of a home. Beyond energy savings, it helps preserve the building's structure and improve the quality of life for its occupants.
Reduce thermal losses and energy consumption
A poorly insulated house loses up to 30% of its heat through the walls, 25% through the roof, and 10% through the floor. By improving insulation, these losses are limited, allowing for less energy consumption for heating and cooling.
Improve indoor comfort all year round
Good insulation ensures a consistent temperature in all rooms and prevents cold wall sensations or drafts. Residents thus enjoy constant well-being, both in summer and winter, without sudden fluctuations.
Enhance your property value
In Luxembourg, a well-insulated home benefits from a better energy rating, a major advantage when selling or renting. This enhancement attracts more buyers or tenants and allows for a better price.
Reduce your environmental footprint
By consuming less energy, your home emits less CO₂. Insulation is therefore a concrete action to contribute to the fight against climate change while achieving sustainable savings.

The different types of insulation offered by Avenir Rénovations Luxembourg
Each type of insulation meets specific needs according to the configuration of the home and the areas of heat loss to be addressed.
Roof insulation is the priority in any energy renovation project, as it is where most heat escapes. Our experts insulate your lost or convertible attics with high-performance materials for optimal comfort.
This technique involves placing insulation on the interior walls to enhance the energy performance of the home. It is ideal when the facade cannot be altered or for listed buildings.
External thermal insulation (ITE) not only improves energy performance but also enhances the aesthetics of the facade. This method wraps the building in a continuous insulating layer, eliminating thermal bridges.
Often overlooked, insulating the ground floor helps prevent cold rising from the basement, garage, or crawl space. It is an essential step to optimize the overall comfort of your home.
Joinery is a significant area of heat loss. By opting for high-performance double or triple glazing windows, you significantly improve the thermal and acoustic insulation of your home.
How much do insulation works cost in Luxembourg?
The cost of insulation depends on the type of surface to be insulated, the chosen material, and the technique used. Here is an estimate of the average rates observed.
| Type of service | Price per m² (EUR) | Average total price (EUR) |
| Insulation of lost attics | 43 to 62 € | 1,900 to 3,800 € |
| Roof insulation | 95 to 171 € | 7,600 to 14,250 € |
| Wall insulation from the inside | 57 to 95 € | 3,800 to 8,550 € |
| Wall insulation from the outside | 114 to 190 € | 7,600 to 19,000 € |
| Insulation of the ground floor | 48 to 86 € | 1,900 to 5,700 € |
These amounts include supply, installation, and labor, but a tailored quote is essential for an accurate estimate based on the surface area, materials, and technical constraints.
What insulation materials to use?
The choice of materials depends on the desired performance, budget, and type of building. Avenir Rénovations Luxembourg advises you on the most suitable products for your project.
Mineral wool (glass or rock wool)
Widely used, it offers excellent thermal and acoustic resistance at an affordable cost. It is ideal for insulating attics, walls, and partitions.
Expanded or extruded polystyrene
Lightweight and efficient, this material is often used for external insulation of facades. It has very good moisture resistance and an excellent cost-performance ratio.
Wood fiber
A natural and ecological material, wood fiber is valued for its thermal and acoustic properties. It regulates humidity and improves summer comfort due to its high inertia.
Expanded cork
Ecological, rot-proof, and durable, cork is a high-performing natural insulator, ideal for floors and interior walls. It also has good sound insulation qualities.
Cellulose wadding
Made from recycled paper, it is a sustainable and ecological solution. It is suitable for lost attics, partitions, and timber-framed walls.

Regulations on insulation in Luxembourg
Before starting insulation work, it is essential to know the legal obligations and standards in force in Luxembourg. These regulations ensure the quality of the work and its compliance with national energy requirements.
Permits and administrative procedures
For interior insulation work, no specific permit is generally required. However, external insulation, particularly through the facade, may require a municipal permit, especially if it alters the appearance of the building or encroaches on public space. Avenir Rénovations Luxembourg assists you in all the steps to obtain the necessary permits.
Energy standards to be met
Luxembourg imposes high standards regarding the energy performance of buildings. Insulation work must comply with the Grand-Ducal regulation on the energy performance of buildings (PEB), which defines the maximum thermal transmission coefficients (U). These values ensure an effective and sustainable level of insulation.
Available aids and subsidies
The Luxembourg state actively encourages energy renovation through financial aids such as subsidies from the Klimabonus program. These aids cover part of the expenses related to thermal insulation, whether for attics, walls, or floors. Avenir Rénovations Luxembourg helps you prepare your aid application to maximize your funding.
Work in co-ownership or terraced houses
In collective buildings or terraced houses, the insulation of exterior walls often requires the agreement of the co-ownership or neighbors. Our advisors check the feasibility of the work for you while respecting the specific regulations for each case.
Safety and environmental impact
All materials used must comply with European standards regarding fire safety, VOC (volatile organic compounds) emissions, and environmental impact. Avenir Rénovations Luxembourg prioritizes sustainable and ecological insulators, reducing the overall carbon footprint of the project.
Additional benefits of good insulation
A profitable long-term investment
Even though insulation represents an initial cost, the savings made on energy bills allow for a quick amortization of this investment. Depending on the case, the return on investment occurs between 5 and 10 years, while increasing the property value.
Improved acoustic comfort
Insulation is not limited to temperature: it also plays a crucial role in reducing noise disturbances. Modern materials absorb external and internal noises to provide a peaceful and pleasant atmosphere.
Better indoor air quality
Well-designed insulation, combined with appropriate ventilation, prevents condensation and mold formation. It thus promotes healthier indoor air, essential for the health of the occupants.
An ecological contribution
By insulating your home, you actively participate in the energy transition. Less heating means lower CO₂ emissions and better use of natural resources, which perfectly aligns with Luxembourg's climate objectives.
