🔍 Which building elements are worth insulating?

wall insulation

External Wall Insulation

The greatest heat losses occur through uninsulated external walls. We offer wall insulation with polystyrene, mineral wool and polyurethane foam (PUR). Wall insulation improves the insulation of the building and eliminates the problem of moisture and mold. The most popular wall insulation methods in Luxembourg: ETICS system - external thermal insulation using polystyrene or mineral wool. Spray wall insulation - polyurethane foam perfectly seals any surface. Insulation of walls from the inside - an effective solution for historic buildings where external insulation cannot be used.

roof insulation

Roof and Attic Insulation

Warm air rises upwards, which is why proper roof and attic insulation is crucial. We recommend insulating the attic with PUR foam, mineral wool or cellulose, which provides excellent thermal and acoustic properties. Roof and attic insulation methods: Polyurethane foam spray (PUR) - effective sealing of even hard-to-reach places. Roof insulation with mineral wool - high fire resistance and good acoustic insulation. Eco-friendly cellulose insulation - a natural solution with high efficiency.

basement insulation

Basement and Foundation Insulation

Lack of proper insulation of the basement and foundations leads to cooling of the rooms on the ground floor and damp walls. We perform waterproofing and thermal insulation of foundations, which protects the building from heat loss and moisture. Most commonly used methods of foundation insulation: XPS Styrofoam (extruded polystyrene) - resistant to water, perfectly insulates foundations. Sprayed polyurethane insulation - seals and insulates at the same time. PIR boards - a modern solution with a very high insulation coefficient.

floor insulation

Insulation of Ceilings and Floors

Lack of proper insulation of ceilings and floors causes significant heat loss, especially in houses with unheated basements or ground floor premises. Proper insulation of these elements improves thermal comfort, reduces energy loss and eliminates the problem of cold floors. The best methods of insulating ceilings and floors: EPS/XPS polystyrene boards - a lightweight and effective solution for floors and ceilings above basements. Mineral wool - ideal for insulating wooden ceilings, also provides good acoustic insulation. Sprayed polyurethane foam (PUR) - jointless sealing eliminating thermal bridges. PIR boards - a modern solution with a very high insulation coefficient, used mainly in floors on the ground. Thanks to the insulation of ceilings and floors, you can improve the energy efficiency of the building, minimize heat loss and ensure comfortable conditions inside all year round.

Different methods, one result

🏠 Which insulation method should I choose?

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

Styrofoam (EPS – expanded polystyrene)

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:

  • Low weight, which facilitates transport and installation
  • Good thermal insulation (λ = 0.031 – 0.045 W/mK)
  • Resistance to moisture and fungi
  • Relatively low cost compared to other materials

❌ Contraindications:

  • Low resistance to high temperatures – not suitable for places exposed to strong UV radiation or close to heat sources
  • Poor acoustic insulation
  • May be subject to mechanical damage

Extruded polystyrene (XPS)

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:

  • Very low water absorption (ideal for places exposed to moisture)
  • High compressive strength, suitable for mechanical loads
  • Better thermal insulation than EPS (λ = 0.029 – 0.040 W / mK)
  • Lange Lebensdauer


❌ Contraindications:

  • Higher price compared to standard polystyrene
  • Lower vapor permeability, which can lead to problems with moisture in walls without adequate ventilation
  • Not resistant to chemical solvents

Mineral wool (glass and rock)

Mineral wool (glass and rock)

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:

  • Excellent thermal insulation (λ = 0.030 – 0.045 W / mK)
  • High fire resistance – non-flammable material (class A1)
  • Very good acoustic insulation, dampens sounds in the building
  • Vapor permeability – allows walls to “breathe”


❌ Contraindications:

  • May absorb moisture, therefore requires appropriate protection against water
  • Higher weight compared to EPS and XPS
  • Dusting during installation – respiratory protection required

Polyurethane foam (PUR – spray foam insulation)

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:

  • High thermal insulation (λ = 0.022 – 0.030 W/mK)
  • No thermal bridges – uniform insulating layer
  • Very low water absorption, resistance to mold and fungi
  • Durability and resistance to settling


❌ Contraindications:

  • Expensive compared to traditional insulating materials
  • Requires specialist equipment for application – it cannot be installed independently
  • Not resistant to UV radiation, requires protection

  • Sensitivity to some chemical solvents

Cellulose (eco-friendly blown-in insulation)

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:

  • Ecological and sustainable solution (recycled raw material)
  • Very good thermal and acoustic insulation (λ = 0.037 – 0.040 W / mK)
  • No thermal bridges – fills every gap
  • Humidity regulation – does not retain water, but allows walls to “breathe”


❌ Contraindications:

  • May require impregnation against moisture
  • Sensitive to settling over a longer period of time
  • Necessity to use specialist application equipment
