Effective insulation of a house in Luxembourg is the key to lower heating bills, greater living comfort and better energy efficiency. Thanks to modern methods of insulating walls, attics, roofs, basements, ceilings and floors, you can significantly reduce heat loss and reduce energy consumption. Using polystyrene, mineral wool, PUR foam or PIR boards, we provide excellent thermal insulation, protecting the building from moisture, cold and overheating on hot days.
We offer comprehensive thermal insulation services for buildings, including design, selection of appropriate materials and professional execution. Our solutions meet the highest energy efficiency standards, which translates into significant savings and an increase in the value of the property. Additionally, we help in obtaining subsidies for Thermal barrier in Luxembourg, which allow for partial financing of the investment.
Take advantage of our knowledge and experience to make your home warmer, more ecological and energy-efficient all year round. Invest in effective building insulation and enjoy lower operating costs and maximum living comfort!
Did you know that proper home insulation can reduce energy bills by up to 50%? Professional building thermal sollution is the key to lower heating costs, greater living comfort and environmental protection.
✔ Lower heating and air conditioning bills – a well-insulated home needs less energy to maintain an optimal temperature.
✔ Greater comfort all year round – in winter the heat stays inside, in summer the house does not overheat.
✔ Lower CO₂ emissions – Thermal barrier allows you to reduce energy consumption, which translates into ecology.
✔ Increase in property value – modern insulation solutions increase the attractiveness of the building.
✔ Possibility of obtaining subsidies – in Luxembourg, government subsidies for thermal insulation are available.
The largest heat losses in buildings often occur through poorly protected external walls. At Voltmax, we improve the energy efficiency of your home by applying high-quality solutions such as polystyrene, mineral wool, or polyurethane foam (PUR). Adding an extra layer to the walls not only helps keep the heat in but also prevents issues like moisture and mold. In Luxembourg, the most popular methods for improving wall thermal performance include: ETICS system – external protection using polystyrene or mineral wool, commonly used in modern homes. Spray foam application – polyurethane foam creates a seamless barrier that fits any surface perfectly. Interior wall treatment – ideal for historic buildings where modifying the facade is not an option. These solutions increase comfort, reduce heating costs, and help maintain a healthy indoor environment.
Since warm air naturally rises, the roof and attic are areas where significant heat loss can occur. That’s why proper protection in these spaces is essential for improving your home’s energy efficiency. At Voltmax, we recommend using PUR foam, mineral wool, or cellulose—materials known for their excellent thermal and acoustic performance. Popular methods for protecting the roof and attic include: Polyurethane foam spray (PUR) – perfect for sealing even hard-to-reach corners and irregular surfaces. Mineral wool installation – offers high fire resistance along with soundproofing benefits. Cellulose filling – an eco-friendly and highly effective solution made from natural materials. These options help maintain consistent indoor temperatures, reduce heating costs, and increase comfort all year round.
Without proper protection, basements and foundations can become a source of significant heat loss and moisture problems. Cold floors on the ground level and damp walls are often the result. At Voltmax, we carry out both waterproofing and the application of an insulating layer around the foundations to shield your building from unwanted cooling and humidity. Popular foundation protection methods include: XPS Styrofoam (extruded polystyrene) – highly resistant to water and ideal for foundation applications. Spray-applied polyurethane foam – combines insulation and sealing in one efficient process. PIR boards – a cutting-edge solution offering excellent thermal performance with minimal thickness. By properly securing your foundations, you not only improve the comfort of your home but also protect its structure for the long term.
Poorly protected ceilings and floors are a major source of heat loss, especially in buildings with unheated basements or ground-level spaces. By securing these areas, you can significantly improve thermal comfort, reduce energy waste, and eliminate the problem of cold floors. Effective solutions include: EPS/XPS boards – lightweight and efficient, ideal for floors and ceilings above basements. Mineral wool – great for wooden ceilings, also enhances sound insulation. Spray polyurethane foam (PUR) – seamless application that eliminates thermal bridges. PIR boards – ultra-efficient and perfect for insulating floors in contact with the ground. Improving floor and ceiling protection boosts the building’s overall energy efficiency and ensures a comfortable indoor climate all year round.
Different methods, one result
The choice of insulation method for a building depends on the type of construction, budget and customer expectations. Our experienced team of advisors will help you choose the best thermal insulation solutions to make your home warmer, more energy-efficient and comfortable.
In Luxembourg, subsidies for thermal insulation are available, thanks to which you can significantly reduce investment costs.
Available Funding Programs: As part of thermal modernization, you can use various forms of financial support, including subsidies, tax relief or low-interest loans for ecological investments. These programs are often aimed at specific activities, such as thermal insulation, replacing windows and doors, modernizing heating systems or installing photovoltaics. By choosing our company, you receive support throughout the application process – from preparing the necessary documents to consulting on choosing the right programs.
Styrofoam is one of the most commonly used insulating materials due to its lightness, ease of installation and good thermal insulation. Its main application is the insulation of external walls in the ETICS system (light-wet insulation) and foundations.
✅ Advantages:
❌ Contraindications:
XPS is an improved version of polystyrene with a higher density and closed cell structure, which gives it better resistance to moisture and greater mechanical strength. It is mainly used in the insulation of foundations, floors on the ground and inverted roofs.
✅ Advantages:
❌ Contraindications:
Mineral wool is an excellent choice for buildings where, in addition to thermal insulation, fire resistance and good acoustic insulation are also important. It is used in the insulation of roofs, attics, partition walls and ventilated facades.
✅ Advantages:
❌ Contraindications:
PUR foam applied by spraying creates a seamless insulating layer that perfectly adapts to the shape of the insulated surface. It is often used in the insulation of attics, roofs, frame walls and foundations.
✅ Advantages:
❌ Contraindications:
PIR boards are a modern insulating material with an exceptionally low thermal conductivity coefficient, which allows the use of thinner insulation layers. They are mainly used in roof, wall and floor insulation.
✅ Advantages:
❌ Contraindications:
Cellulose is a natural insulating material made from recycled paper, protected against mold and rodents. It is applied using the blowing method, which allows for precise filling of hard-to-reach places in walls and ceilings.
✅ Advantages:
❌ Contraindications:
The choice of the right insulating material depends on the type of building, the specific needs of the investor and the budget.
Styrofoam and XPS are the most commonly used, economical solutions, mineral wool provides fire and acoustic resistance, PUR foam and PIR boards offer the highest insulation, and cellulose is an ecological option for conscious users.
Each material has its own unique properties, so it is worth consulting the choice with an expert to ensure the optimal energy efficiency of the building.
