Roof window ventilation

What makes a FAKRO roof window better?

FAKRO roof windows are designed to provide a focal point for any room whether you use them individually or in combinations. Their stylish appearance is matched by the highest standard of manufacturing and finishing which means you can rest assured they will go on looking good for years to come. Our windows offer a perfect combination of style, sustainability, security and long design life.

To achieve such high performance involves ongoing refinement and improvement to every roof window that we design.


Energooszczędna konstrukcja      

The highest level of energy saving performance

What really sets FAKRO windows apart is their low level of heat loss. Unlike some manufacturers who provide U-values just for glazing units, FAKRO provides information for the whole window. When comparing our performance with other products you will see how our non-vented, quadruple glazed FTT U8 Thermo, with a U-value of 0.58 W/m2K, leads the market. Our standard FTP-V centre pivot windows also offer a level of performance which competing windows invariably fail to match.

Duża ilość naturalnego światła

Ample natural light

The design of FAKRO roof windows provides appropriate illumination of the room within the loft space. Specially shaped profiles of the frame and sash as well as an air inlet location in the upper part of the frame allows for the influx of high quantities of natural light.

Window reinforced structure – topSafe system

Window reinforced structure – topSafe system
Roof windows have to ensure safety of use and protect against easy access to the room from the outside. The patented system of the window structure reinforcement topSafe significantly improves resistance of roof windows to break-in attempts and protects against the sash opening under foot pressure if inadvertently stepped on.

The topSafe system consists of: 

  • innovative installation system
  • specially shaped hinges
  • metal element strengthening the locking system
  • metal slat making break-in attempts with the use of tools much more difficult
III safety class

III safety class
Toughened glass together with the topSafe reinforced structure found on FAKRO roof windows enable them to meet the minimum class III safety for the whole window including glazing as per EN 13049. FAKRO was the first company to introduce to the market a full range of windows achieving at least class III safety, setting a new standard in the roof window sector.

Anti-burglary protection Anti-burglary protection
Anti-burglary protection is a crucial issue in FAKRO products. The standard window for pitched roofs – the FTP-V P2 Secure and flat roof windows – DMF DU6 and DXF DU6  meet European 2nd anti-burglary class RC 2 N as per EN 1627. In addition, flat roof windows type DMF DU6 and DXF DU6 feature the highest impact resistance class SB1200 as per EN 1873. Installation of this type of windows in the roof considerably enhances safety and anti-burglary resistance of the building.

Timber quality
The pine we use offers the clearest visual evidence of our roof window quality. Not only does its close grain look stylish, we obtain timber from FSC certified sources. Our double vacuum process using water-borne preservatives provides lasting dimensional stability and all windows are finished with two coats of environmentally friendly lacquer. Compare this with another leading manufacturer which states - “The timber has received basic treatment and a finished coating at the factory. It must receive further treatment at least every four years and whenever required. Windows exposed to strong heat, strong sunlight and/or high levels of humidity (e.g. in kitchens or bathrooms) must however receive treatment at least every two years”. We therefore actively encourage customers to compare our window finishing with that of other manufacturers.

Windows for bathrooms, wetrooms and kitchens
FAKRO offers two types of roof window for rooms in which high levels of humidity are created. You have the choice of either white polyurethane-coated pine or PVC in white, golden oak and pine finishes. So, whether you want to match existing windows and doors or have a smooth timber finish in white, FAKRO has the perfect solution. FAKRO PVC veneers also achieve the highest level of measurable performance - Class A - EN12608.

Warm glazing spacers
Many roof windows use metallic spacers to separate panes and these can encourage condensation to form by forming a cold ‘bridge’ between them. By contrast, FAKRO uses only warm spacers in order to ensure that this otherwise common problem does not affect our products. 

Ease of installation
Our easy-to-use “bracket fix” installation system enables windows to be fitted either to rafters or battens. Windows can also be fitted onto sarking.

Performance Guarantees
Whether buying natural pine, PU-coated pine or PVC FAKRO offers a 10-year warranty for all windows and glazing units. We also offer a no-quibble lifetime warranty against damage by hail stones.


We are sure of the QUALITY that’s why we offer a long-term warranty.
