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, which means we offer the full product range, direct factory technical advice and prices with no middlemen. We have over 30 years of experience installing roof windows in detached houses, historic buildings in the Albaicín and renovated farmhouses across the Vega de Granada.

Types of FAKRO roof windows for loft conversions

FAKRO offers a complete range of roof windows suited to every roof type, use and budget. 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:

• Property value increase: a renovated attic with roof windows can raise the property's valuation by 15-25% (according to Andalusian real-estate sector studies).
• Energy savings: 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. Our installation team knows these conditions and applies tailored solutions:

Regulations and permits for roof windows in Granada

Installing roof windows in Granada requires compliance with specific regulations:

• CTE DB-HE (energy saving): windows must meet maximum thermal transmittance values for the climate zone. In Granada (C3) the limit is Uw ≤ 2.3 W/m²K. All FAKRO windows comfortably meet this requirement.
• Planning permission: replacing existing windows generally does not require a licence. Opening new roof apertures does require a minor works licence in most Granada municipalities.
• Albaicín-Sacromonte protected zone: in these UNESCO World Heritage areas, any roof modification requires approval from the Municipal Heritage Commission. FAKRO windows in dark wood or with copper flashings are most commonly accepted.
• Community of owners: in apartment buildings, roof window installation may require community approval if it affects communal elements.

• 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°). Our technician assesses feasibility during the free site visit.

How long does installation take?

Installing a standard roof window takes 3 to 5 hours. If a new opening must be cut into the roof, it can take 1-2 days including interior and exterior finishing.

Do roof windows leak?

No, if installed correctly with the appropriate FAKRO flashing kit for the roof type (flat tile, curved tile, slate). Our installations include a 10-year watertightness warranty.
