Why insulate your roof in Luxembourg?
An immediate improvement in thermal comfort
Insulating your roof helps limit heat loss, which accounts for up to 30% of a home's energy losses. This intervention ensures a consistent temperature in the rooms and reduces feelings of cold in winter and excessive heat in summer.
A significant reduction in energy consumption
Good roof insulation decreases dependence on heating and air conditioning. Energy expenses decrease sustainably, resulting in a notable reduction in bills while enhancing the property's value in the long term.
A sustainable increase in property value
Homes with high-performance insulation display a better energy label. This improvement in the Energy Performance Diagnosis (DPE) increases the value of the property, a significant asset in case of sale or rental.
Structural protection of the house
In addition to thermal benefits, roof insulation protects the framework and covering from moisture effects. Well-installed insulation prevents condensation formation and prolongs the roof's lifespan.
The steps of a roof insulation project with Avenir Rénovations Luxembourg
Our experts follow a rigorous process to ensure optimal and durable insulation. Each step is carried out with care to meet technical and regulatory requirements.
The different types of roof insulation offered by Avenir Rénovations Luxembourg
Depending on the configuration of your home and your budget, our experts will advise you on the most suitable method among several recognized techniques for their effectiveness.
This method involves placing insulation on the framework before the covering. It offers excellent thermal performance and avoids any loss of interior space. Ideal during a complete renovation, it ensures perfect continuity of insulation.
Internal insulation involves placing the insulation under the framework, directly in the attic. It is a more economical and quick solution to implement, often preferred for light renovations or converted attics.
When the attic is not habitable, insulation of the attic floor is carried out. This solution effectively limits heat loss from above and is achieved at a lower cost, particularly by blowing in loose insulation.
For contemporary buildings or flat roof extensions, Avenir Rénovations Luxembourg offers rigid insulations suitable for horizontal configurations. These materials guarantee perfect waterproofing and excellent durability against the elements.
How much does roof insulation cost in Luxembourg?

The materials used for roof insulation
The choice of insulating material depends on the desired performance, the type of roof, and the budget. Our experts select only certified materials suitable for the Luxembourg climate.
Rock wool
Rock wool is a highly effective mineral insulator against cold and noise. It is perfectly resistant to moisture, mold, and fire, ensuring significant longevity over time.
Glass wool
Cost-effective and easy to install, glass wool remains a very popular solution. Its excellent thermal and acoustic performance makes it an ideal material for converted or unconverted attics.
Polyurethane
Polyurethane offers very high insulating power with a low thickness. It is particularly suitable for flat roofs and renovations requiring thin insulation without losing interior volume.
Wood fiber
An ecological and breathable material, wood fiber naturally regulates humidity and temperature. It provides exceptional summer thermal insulation, making it a preferred choice for timber-framed houses or eco-designed buildings.

Regulations regarding roof insulation in Luxembourg
Before starting roof insulation work, it is essential to comply with the regulations in force in Luxembourg. Avenir Rénovations guides you through all the administrative procedures to ensure your project's compliance.
Municipal authorizations and building permits
In certain cases, particularly for external roof insulation (sarking) or any visible modification of the roof, a municipal authorization is required. The file must include the project plans and the materials used. Our experts can assist you in preparing this file.
Compliance with energy standards
The insulation work must meet the requirements of Luxembourgish regulations regarding the energy performance of buildings (PEB). The insulation materials used must guarantee a low thermal transmittance coefficient (U) to optimize overall energy efficiency.
Work in co-ownership
If your dwelling is in co-ownership, authorization from the general assembly is necessary before any intervention. Avenir Rénovations Luxembourg ensures your project's compliance with the building's internal regulations.
Environmental standards and sustainability
The materials used must comply with environmental standards and have a low ecological impact. The Avenir Rénovations team prioritizes certified, recyclable products that are respectful of the occupants' health.
Financial aid for roof insulation in Luxembourg
The Luxembourg government encourages high-performance insulation work through several aid and grant schemes.
Grant for energy renovation
This grant is intended for individuals undertaking insulation work in their primary residence. The amount varies according to the performance achieved and the insulated area.
Municipal and cantonal support
Some municipalities offer additional grants to encourage thermal renovations. Avenir Rénovations can help you identify and apply for these local aids.

FAQ on roof insulation in Luxembourg
Is a permit required to insulate your roof in Luxembourg?
Yes, if the work modifies the exterior appearance of the building, especially for external insulation. In other cases (interior insulation or lost attics), a simple declaration may suffice depending on the municipality.
What is the lifespan of roof insulation?
Well-installed and maintained insulation can last between 30 and 50 years. Modern materials like rock wool or polyurethane retain their thermal properties for several decades.
Can you insulate an old roof without completely replacing it?
Yes, interior or blown insulation can improve energy performance without removing the existing covering. This method is ideal for old buildings with solid frameworks.
What materials offer the best value for money?
Glass wool and rock wool remain the most economical while ensuring good thermal performance. Polyurethane and wood fiber are better suited for projects requiring high energy efficiency.
Does roof insulation improve sound insulation?
Absolutely. In addition to reducing thermal losses, insulating materials dampen external noises such as rain, wind, or traffic, contributing to better acoustic comfort.
Can insulation and roof renovation be combined?
Yes, it is strongly advised to combine these works. This optimizes energy performance and avoids having to dismantle the covering again in the short term.
