Types of windows available in Luxembourg

Compare the main frame materials. The right choice depends on your home, exposure, budget and desired finish.

PVC windows

PVC is the most common material for windows in Luxembourg. It offers excellent thermal insulation, good value for money and virtually no maintenance.

Indicative range: 500 to 1,200 euros per installed window, depending on dimensions and glazing.

Strengths

  • High-performing thermal insulation
  • Controlled price
  • Very limited maintenance
  • Wide choice of colours and finishes

Points to watch

  • Thicker profile sections
  • Long-term colour retention of dark shades to monitor

Bay windows, French doors and roof windows

Beyond standard windows, Luxembourg carpenters also work on specific formats that transform light input and room use.

Bay windows

Sliding, pocket or lift-and-slide bay windows. Ideal for opening a living room onto a terrace or garden, with large aluminium glazed areas to make the most of the light.

French doors

Classic solution for accessing a balcony, terrace or garden. Available in PVC, wood or aluminium, double or triple glazing, with or without an accessible threshold.

Roof windows

Velux or equivalent windows for converted lofts, under-roof spaces and extensions. Natural light input and ventilation, with glazing adapted to large temperature variations.

Installation, replacement and renovation of windows

Depending on the condition of your openings and your objective, work can range from simply replacing the sash to fully replacing the frame and masonry.

Installing new windows

For new construction or extension. The carpenter works from plans and installs windows in masonry designed from the start to accommodate them. Adjustments are made with precision, without constraints related to existing structure.

Replacing existing windows

Two common approaches in Luxembourg: full removal (frame and sash removed, better performing but heavier site) or renovation on existing frame (faster, less costly, slight reduction in glazed area).

Renovating old openings

On traditional Luxembourg buildings or listed houses, it is sometimes preferable to restore original carpentry rather than replace it. The carpenter can rework wood, hardware and seals while improving the glazing.

Improving thermal and acoustic insulation

Replacing windows is one of the most effective levers to reduce energy loss and noise. Combine high-performance glazing, thermally broken frames and careful installation for a lasting result.

Why choose the right glazing?

Glazing represents a large part of a window's performance. It affects thermal comfort, sound insulation, energy consumption and room use.

Glazing typeIndicative Ug coefficientRecommended useSound insulation
Single glazing5.8 W/m²KEmergency repair, unheated buildingVery low
Double glazing1.0 to 1.1 W/m²KStandard for most Luxembourg homesGood, reinforced option available
Triple glazing0.5 to 0.7 W/m²KPassive houses, low-energy buildings, very noisy areasExcellent

The lower the Ug coefficient, the better the thermal insulation. For acoustics, an asymmetric laminated glazing can be more effective than standard triple glazing, depending on your home's exposure.
