Roof Windows for Loft Conversions: FAKRO Guide 2026

Introduction: transform your loft with FAKRO roof windows

Lofts and attics are the most underused spaces in homes across Granada. Many families have square metres under the roof that could become bedrooms, studies or playrooms, but dismiss them due to a lack of natural light and ventilation. FAKRO roof windows solve exactly this problem: they deliver up to 40% more natural light than an equivalent vertical window (according to FAKRO manufacturer data), turning dark spaces into comfortable rooms.

At Tecnisun C.B. we are exclusive FAKRO distributors in Granada and official installers of the brand, which means we work with the full range and with direct technical advice. With over 25 years in the trade, we know detached houses, historic buildings in the Albaicín and renovated farmhouses across the Vega de Granada well.

Types of FAKRO roof windows for loft conversions

FAKRO offers a complete range of roof windows suited to every roof type and use. As exclusive distributors in Granada, we work with every model:

FTP-V: the best-selling centre-pivot window

The FTP-V series is the most popular model for habitable lofts. Its centre-pivot opening allows comfortable ventilation and lets you clean the exterior glass from inside by rotating the sash 180°. Available in PVC (FTP-V U5) and pine wood with acrylic varnish (FTP-V U3). Thermal insulation values reach Uw 1.0 W/m²K in the U5 version, comfortably exceeding CTE requirements for Granada's C3 climate zone.

FTT: triple glazing for maximum insulation

The FTT ThermoPro series features triple glazing with argon gas and low-emissivity coating, achieving Uw values as low as 0.77 W/m²K (per FAKRO technical datasheet). It is the recommended option for properties in Sierra Nevada, the higher areas of Granada and any location with harsh winters. The PVC frame eliminates thermal bridges and resists condensation even with extreme temperature differences.

FPP-V: top-hung projecting opening

The FPP-V series combines pivot opening with a top-hung projecting opening, allowing the window to remain ajar in permanent ventilation mode without letting rain in. Ideal for loft kitchens and bathrooms where constant ventilation is needed.

Special windows: balconies, roof access and skylights

FAKRO also manufactures balcony windows (FGH-V Galeria) that transform into a balcony when opened, roof access exits for maintenance, and fixed skylights for illumination without opening. At Tecnisun we advise on the best combination for your project.

Benefits of installing roof windows in your loft

Converting a loft into living space with FAKRO windows provides tangible benefits that go far beyond aesthetics:

• A more complete home: a renovated attic with roof windows adds a useful, bright room to the house.
• Energy efficiency: natural ventilation through the chimney effect reduces air-conditioning needs in summer, while FAKRO's thermal insulation minimises heat loss in winter.
• Health and wellbeing: overhead light stimulates vitamin D production and regulates circadian rhythms, improving sleep and mood.
• Additional living space: without expanding the building footprint, you gain functional square metres by using the existing roof space.
• Natural ventilation: roof windows create natural air currents that refresh the interior without mechanical systems.

Roof window installation in Granada's climate

Granada's climate poses specific challenges for roof windows: cold winters with frequent frost (down to -10°C in mountain areas), intense summers with high solar radiation, and occasional snowfall at mid-altitude. We know these conditions and apply tailored solutions:

Regulations and permits for roof windows in Granada

Installing roof windows must comply with the applicable regulations. As general guidance:

• CTE DB-HE (energy saving): windows must meet maximum thermal transmittance values for the climate zone. FAKRO windows comfortably meet this requirement for Granada's C3 zone.
• Planning permission: replacing existing windows is usually a simple procedure; opening new roof apertures usually requires a works licence in most municipalities. Each town council sets its own requirements.
• Albaicín-Sacromonte protected zone: in these UNESCO World Heritage areas, roof modifications require additional authorisations. FAKRO windows in dark wood or with copper flashings tend to blend in best.
• Community of owners: in apartment buildings, roof window installation may require community approval if it affects communal elements.

We advise you on the procedure your case requires.

What does the quote for a FAKRO roof window depend on?

There is no single price: it depends on the model, size, glazing, accessories and, above all, the complexity and accessibility of the roof. These are the models we install most in Granada:

Essential accessories for roof windows

FAKRO roof windows achieve peak performance when combined with the right accessories:

• AMS mosquito screen: compatible with all FAKRO windows. Tool-free installation.

Frequently asked questions about FAKRO roof windows

Can a roof window be installed on any roof?

Yes, provided the pitch is between 15° and 90°. FAKRO has specific models for low pitches (15-55°) and steep pitches (25-90°). We assess feasibility from the photos and measurements you send and, if needed, during a technical visit (which has a cost, which we tell you beforehand).

Is it a complicated job?

Replacing an existing roof window is a contained job. If a new opening must be cut into the roof, the works are larger because they include interior and exterior finishing. The quote explains how it will be organised in your case.

Do roof windows leak?

They should not, if installed correctly with the appropriate FAKRO flashing kit for the roof type (flat tile, curved tile, slate). FAKRO provides its own warranty, subject to the manufacturer's terms.

Is the quote free?

Yes. The online quote is free and without obligation. The technical home visit has a cost, which we tell you before arranging it.
