FAKRO Roof Windows: Everything You Need to Know Before Installing

By Tecnisun C.B.

What Are FAKRO Roof Windows?

Roof windows, also known as skylight windows or dormer windows, are purpose-built fenestration designed for installation in pitched roofs. They transform under-roof spaces into habitable, bright and well-ventilated rooms. FAKRO, the world's second-largest manufacturer of roof windows, offers a complete range combining technological innovation, energy efficiency and durability.

At Tecnisun C.B. we are the exclusive distributors of FAKRO in the province of Granada and official installers of the brand, allowing us to offer the full product range with specialised technical advice and professional installation. With over 25 years in the trade, we know the roofs of homes, attics and lofts across Granada and its province well.

💡
Did you know?

A loft space with FAKRO roof windows can gain up to 40% more natural light than with conventional vertical windows of the same size. This is because the angle of incidence of sunlight through the roof slope allows deeper and more uniform illumination of the space.

Types of FAKRO Roof Windows

FAKRO offers different series adapted to every need. The two main materials are PVC and wood, each with specific advantages depending on the installation environment and project requirements.

FAKRO FTP-V — PVC Roof Window

The FTP-V series is the most requested for homes in Granada thanks to its balanced performance and total moisture resistance. Made by FAKRO with multi-chamber PVC profiles reinforced with galvanised steel, it offers exceptional thermal insulation with zero maintenance required.

  • Centre-pivot opening: 180° rotation for exterior cleaning from inside
  • Laminated safety glass: resistant to impacts and hail
  • topSafe system: integrated safety device against falls
  • Moisture resistance: ideal for bathrooms, kitchens and humid zones under the roof
  • Uw values: from 1.0 W/m²K (U5 model with triple glazing)

FAKRO FTT — Timber Roof Window

The FTT series is manufactured from laminated pine wood with triple protective treatment. It is the preferred choice for spaces where a warm, natural aesthetic is desired, such as bedrooms, loft living rooms or studios.

  • Nordic pine wood: fungicidal, insecticidal and hydrophobic treatment
  • White lacquered or natural finish: perfect integration with any décor
  • Triple glazing available: Uw from 0.85 W/m²K
  • Microventilation system: air renewal even with the window closed
  • Motorised options: electric opening with remote control or home automation

Benefits of Installing Roof Windows

Installing FAKRO roof windows in your Granada home radically transforms under-roof spaces. These are the main benefits our clients highlight after installation:

Abundant Natural Light

A 78x118 cm roof window provides light comparable to a considerably larger vertical window. Being positioned on the roof slope, it captures direct sunlight for more hours per day, especially in winter when the sun is low. In Granada, with over 2,800 hours of sunshine annually, the natural light harvesting is exceptional.

Efficient Ventilation

Roof windows harness the natural chimney effect: when you open the upper window, hot air rises and evacuates, creating a natural ventilation current that renews the room's air. This is especially useful during Granada's hot summers, where temperatures under the roof can easily exceed 45°C without adequate ventilation.

Energy Efficiency

FAKRO windows with triple glazing and low-emissivity coating reduce heat loss in winter and limit excessive solar gain in summer. The result is a comfortable space year-round, with less reliance on heating and cooling than with old skylights or no ventilation.

More Living Space

Converting an under-roof space into habitable area adds usable square metres to your home: a study, a bedroom or a playroom where there used to be a storage room. It is one of the improvements that most changes how a house is used.

Professional tip

To maximise natural light, we recommend installing roof windows on the south or southeast-facing slope. In Granada, this orientation provides direct sunlight for much of the day even during winter months. If you need cross ventilation, combine windows on two opposite slopes.

Roof Window Installation: Technical Considerations

Installing a roof window is not a DIY job. It requires specific knowledge of construction, waterproofing and building regulations. These are the key factors we evaluate in every project:

  • Roof type: flat tiles, curved tiles, slate, sheet metal — each material requires a different flashing kit
  • Roof pitch: the incline determines the window type and optimal opening system (15° to 90°)
  • Load-bearing structure: rafters and purlins must be assessed to determine if structural reinforcement is needed
  • Waterproofing: correct sealing with the roof membranes is critical to prevent leaks
  • Planning regulations: in some Granada districts (Albaicín, Historic Centre) specific permission may be required
  • Perimeter insulation: the gap between the window frame and roof structure must be filled with appropriate insulation

You can start with a free, no-obligation online quote by sending us measurements and photos of your roof. If needed, the technical home visit has a cost, which we tell you before arranging it. Every installation includes the FAKRO flashing kit specific to your roof type and professional waterproofing.

Caring for FAKRO Roof Windows

One of the great advantages of FAKRO windows is their low maintenance. Our recommendations to keep them in perfect condition for decades:

  • Glass cleaning: a few times a year, rotating the sash 180° to access the exterior comfortably from inside
  • Gutter cleaning: check and clean drainage channels before the rainy season
  • Weatherseals: inspect visually from time to time and replace if cracked
  • Hinges and hardware: lubricate with silicone oil
  • Dust filter: clean or replace periodically (models with integrated ventilation)
  • Varnishing (wood models only): periodically, using original FAKRO varnish

What Does the Quote for a FAKRO Roof Window Depend On?

There is no single price: the quote depends on the model, size, glazing type, the flashing kit for your roof, accessories and the complexity of the installation. These are the most requested models in Granada:

Frequently Asked Questions About FAKRO Roof Windows

Can roof windows be installed on any type of roof?

Yes, FAKRO manufactures flashing kits for all roof types: flat tiles, curved tiles (very common in Granada), slate, corrugated sheet, etc. The only essential requirement is a minimum roof pitch of 15° (although special solutions exist for flat roofs).

Is there a risk of leaks?

With professional installation, there should not be. The FAKRO waterproofing system includes a flashing with lead or aluminium apron that integrates under the tiles, creating a hermetic seal.

Do I need planning permission to install roof windows?

It depends on the municipality and the area. In many cases a prior notification to the Town Hall is enough, but in protected areas such as the Albaicín or the Historic Centre of Granada, planning permission may be required. We advise you on the procedure for your case.

Can roof windows be motorised?

Yes. FAKRO offers factory-fitted electric models and motorisation kits for manual models. Electric versions include a rain sensor that automatically closes the window if it starts to rain.
