Why choose Avenir Renovations?
The elements that determine the installation price of windows
In Luxembourg, the budget required to install new windows can vary significantly depending on several parameters. Whether it is a renovation project aimed at improving energy performance or new construction, the total cost includes both the supply of joinery and installation fees.
The type of glazing is one of the main criteria influencing the price of a window. It plays a major role in the thermal and acoustic insulation of the home, and its choice depends on comfort and energy efficiency requirements.
Today, single glazing has become marginal, as it offers limited insulation despite a lower cost. Double glazing remains the most common solution in Luxembourg, as it provides a good compromise between performance and budget. Triple glazing, on the other hand, is particularly suitable for low-energy homes or those located in cold or noisy environments.
Some models also incorporate reinforced insulation glazing or argon gas filling, further optimizing energy performance.
The windows installed in Luxembourg are mainly made of PVC, aluminum, or wood, sometimes with mixed wood/aluminum combinations.
PVC is appealing due to its accessible price and low maintenance, making it a very common choice. Wood, valued for its warm appearance and natural insulating qualities, requires regular maintenance. Aluminum, known for its robustness and contemporary aesthetics, offers excellent durability but generally represents a higher investment.
The chosen material influences not only the purchase cost but also the installation method and the required technicality.
The size of the windows has a direct impact on the budget. The larger the glazed area, the greater the amount of materials and the complexity of manufacturing increases. A large sliding glass door will naturally cost more than a small standard window.
At Avenir Rénovations Luxembourg, precise measurements are taken to establish a personalized quote perfectly suited to your openings.
The number of sashes also influences the final price. A single-sash window remains more economical than a model with two or three openings. However, a greater number of sashes allows for improved ventilation and brightness. The choice will therefore depend on the configuration of the room and your usage preferences.
The opening mechanism is another determining factor. Traditional casement windows are generally the most accessible. Tilt-and-turn models, which combine classic opening and tilted position, offer more comfort but are more expensive. Sliding systems, often used for large glazed areas, require more technical design. Hopper windows, frequently installed in bathrooms, meet specific needs.
The more elaborate the mechanism, the higher the installation cost.
Finally, the labor cost depends on the number of windows to be installed, the chosen technique, and the specific constraints of the site. In Luxembourg, the average rate for installing a window generally ranges from €100 to €500, depending on the dimensions and necessary adjustments.
Avenir Rénovations Luxembourg provides qualified professionals to ensure a careful, durable installation that complies with current standards while keeping your budget in check.

Window installation prices in Luxembourg by material
In Luxembourg, the material chosen for your windows has a direct influence on the overall budget. Each solution has different characteristics in terms of insulation, durability, and aesthetic appeal. Here are indicative price ranges suited to the Luxembourg market (installation included).
PVC windows: the most economical solution
Widely used, PVC is appreciated for its good level of thermal and acoustic insulation while remaining easy to maintain on a daily basis. It is generally the most accessible option for replacing joinery.
Average price in Luxembourg: between €300 and €750 including VAT (installation included).
Wooden windows: comfort and natural charm
Wood is appealing for its warm appearance and insulating performance. However, it requires regular maintenance to preserve its appearance and withstand the elements over time.
Average price in Luxembourg: between €500 and €1,200 including VAT (installation included).
Aluminum windows: contemporary design and great durability
Aluminum is particularly valued for its modern style, strength, and corrosion resistance. It is also lightweight, making it easier to handle, especially for larger dimensions. To ensure good insulation, it is recommended to choose models with thermal break.
Average price in Luxembourg: between €450 and €1,000 including VAT (installation included).
Mixed wood/aluminum windows: high-end and longevity
Mixed windows combine wood on the inside for aesthetics and comfort, with aluminum on the outside for protection and durability. This more expensive solution is often chosen for premium projects.
Average price in Luxembourg: between €650 and €1,400 including VAT (installation included).
Installation cost of windows in Luxembourg according to the type of glazing
The choice of glazing strongly influences the thermal and acoustic performance of your joinery. In Luxembourg, the installation cost varies depending on the technology chosen and the level of insulation sought. The more efficient the glazing, the higher the initial investment, but long-term energy savings can be significant.
Installation of a PVC window with double glazing
Double glazing is currently the most common solution. Composed of two glass panels separated by an air gap or an insulating gas, it significantly improves insulation compared to single glazing. It helps limit heat loss and reduce noise disturbances, while remaining budget-friendly.
In Luxembourg, the price of a PVC window equipped with double glazing, including installation, generally ranges between 350 € and 900 € VAT included, depending on the dimensions and quality of the joinery.
Cost of a window with triple glazing
Even more efficient, triple glazing is distinguished by enhanced insulation against cold and external noise. Its design, incorporating a third pane and additional insulating layers, explains its higher price. It is particularly suitable for low-energy homes or properties located in areas exposed to low temperatures or significant noise disturbances.
In Luxembourg, the price of a window with triple glazing, installation included, varies on average between 750 € and 1 400 € VAT included, depending on the chosen material and the glazed surface.
Replacement cost of windows in Luxembourg according to the installation technique
In Luxembourg, the cost of changing windows does not only depend on the chosen model. The installation method also plays an important role, as it determines the work time, the level of finish, and the complexity of the project.
Total removal
Total removal involves completely removing the old joinery, including the frame, before installing the new window. This solution is often considered the most effective, as it allows for optimal sealing and a perfectly clean finish. In return, it is also the most expensive technique, as it requires more labor and sometimes masonry work.
Surface-mounted installation
This method involves fixing the window directly onto the masonry, usually as part of an energy renovation or interior insulation. It offers very good results in terms of air tightness and thermal performance. Its cost is generally a bit higher than a renovation installation, as it requires precise adjustments.
Renovation installation (on existing frame)
Renovation installation is the fastest and often the most economical option. It relies on the preservation of the old frame, onto which the new window is fixed. This technique limits the work and reduces the duration of the project, but it is only possible if the existing frame is in good condition.
Financial aid for window replacement in Luxembourg
In Luxembourg, several aid schemes allow you to ease the budget related to the replacement of your windows, especially when the work aims to improve the energy performance of your home. By combining grants and tax benefits, it is possible to significantly reduce the overall cost while increasing the thermal comfort of the dwelling.
State aid for energy renovation
In the context of window replacement, financial aid may be granted provided that the new joinery meets the current technical requirements, particularly regarding the thermal insulation coefficient (Uw).
- The amount of the grant can reach approximately €40 to €60 per m² of glazed surface, depending on the level of energy performance achieved and the criteria applicable at the time of the application.
- Aid is subject to change according to government reforms and national climate goals.
The super-reduced VAT rate of 3%
In Luxembourg, renovation work carried out in a primary residence may, under certain conditions, benefit from a super-reduced VAT rate of 3% instead of the normal rate of 17%.
This tax advantage applies to the supply and installation, within the limit of a legal ceiling set by the administration. It constitutes an important lever to reduce the total cost of replacing your windows, especially as part of a comprehensive energy renovation.
Preferential rate loans
To facilitate the financing of energy improvement work, reduced-rate credit solutions may also be offered by certain partner institutions or as part of public schemes. These loans allow you to spread the cost of the work while maintaining an attractive interest rate.
By combining direct aid, the reduced VAT rate, and any advantageous financing, replacing your windows in Luxembourg becomes a more accessible investment. You thus improve the thermal and acoustic insulation of your home while managing your budget.
