ROOF WINDOWS

Roof Windows – Light, Air and Views under the Roof

Introduction

The attic is often considered the cosiest part of a house. Whether used as a bedroom, study or creative studio, the quality of living under the roof depends largely on how much light and air enters the space. Roof windows play a key role here. They bring daylight under sloped ceilings, improve ventilation and open up new design possibilities. At the same time, they contribute to energy efficiency, indoor comfort, and even increase the property’s value.

What are roof windows?

A roof window is a specially designed window installed directly into the roof surface. Unlike traditional facade windows, it features:

• an inclined installation position,

• extra-robust construction to withstand rain, snow and wind,

• integrated seals, insulation layers and safety mechanisms.

Roof windows are available as classic centre-pivot windows, top-hung windows, panoramic roof windows or even balcony-style roof solutions.

Advantages of roof windows

More daylight
Roof windows allow up to twice as much natural light to enter compared to facade windows of the same size. Rooms appear larger, brighter and more inviting.

Better ventilation
They enable warm air to escape upwards, which improves indoor climate in summer. Combined with facade windows, they provide effective cross-ventilation.

Living comfort and atmosphere
Roof windows open views to the sky, adding charm and a unique atmosphere.

Energy efficiency
Modern roof windows with triple glazing, thermal coatings and insulated frames reduce heat loss and save on heating costs.

Space-saving
Since they do not swing into the room, roof windows are suitable even for compact attic spaces.

Value increase
Adding roof windows enhances living space usability and raises property value significantly.

Disadvantages

• Higher investment compared to facade windows.

• Stronger solar gain can overheat rooms in summer without shading.

• Require regular cleaning and maintenance, as they are more exposed to dirt.

Types of roof windows

• Centre-pivot windows: sash rotates around a central axis, very common and space-saving.

• Top-hung/centre-pivot windows: open outward for unobstructed views.

• Panoramic roof windows: large window constructions for maximum daylight.

• Roof balcony windows: special designs that transform into a mini-balcony when opened.

• Electric roof windows: motorised, sensor-controlled and smart-home compatible.

Materials

• uPVC roof windows: affordable, easy to maintain, and ideal for kitchens or bathrooms.

• Wooden roof windows: natural look, excellent insulation, create a cosy atmosphere, but require more upkeep.

• Wood-aluminium roof windows: premium solution with warm wood inside and weatherproof aluminium outside.

Applications

• Attic bedrooms, children’s rooms or studies.

• Bathrooms and kitchens under pitched roofs.

• Winter gardens, studios and creative loft spaces.

• Schools, offices or public buildings needing light-filled roof levels.

Future trends

• Integrated shading systems such as blinds, shutters or awnings.

• Higher energy efficiency through triple glazing and solar-reflective coatings.

• Smart-home integration with app control, rain sensors and automated ventilation.

• Use of sustainable materials like recycled aluminium or certified wood.

Conclusion

Roof windows are a central element in modern roof design. They bring more daylight and fresh air into attics, improve energy efficiency and enhance property value. Although they require higher upfront investment and regular maintenance, their long-term benefits in comfort and functionality make them indispensable. Anyone looking to transform an attic into a bright and liveable space will find roof windows the ideal solution.
