Safe and comfortable access to the roof 

A larger window size means more freedom – you can easily access the roof, for example, to inspect the chimney, install an antenna, or clean the gutters. The carefully designed dimensions make it easy to pass through and meet building requirements, so you can be sure that everything is in compliance. The sash opens wide and is safely supported by gas springs. An additional PVC strip protects the wood every time you go out.

Simple installation and flexible fit  

FAKRO roof windows are easy to install – they fit the same flashings as roof windows. This allows them to be aesthetically combined with other windows. The installation range of 15 to 55° makes it easy to adjust to different roof pitches. Before installation, you can select the sash opening direction – right or left. The window is supplied as right-hand as standard.

Glazing unit U41

The 44 mm thick triple-glazed unit features two low-emission coatings, glazing cavity filled with argon and a warm TGI spacer. This gives it a very good heat transfer coefficient rated at Uw = 1.0 W/m²K when used with the Thermo flashing. It provides acoustic comfort of 35 dB, which effectively reduces noise and improves conditions for rest in the attic.

External cladding

The external cladding was designed in cooperation with the Institute of Industrial Design. Its modern, minimalist form emphasises the aesthetics of the window and harmonises with the roof line. The anthracite colour (RAL 7016) fits perfectly with current architectural trends. The colour consistency of the cladding, accessories and flashings creates a harmonious, elegant set that is resistant to weather conditions.

Internal finish

Carefully selected pinewood, vacuum-impregnated and coated with a clear acrylic varnish, emphasises the natural character of the wood. This makes your interior cosy, warm and elegant. The finish is durable and resistant to everyday use, maintaining its aesthetic appearance for many years.

Handle

An ergonomic handle located in the middle of the sash allows for quick and easy opening of the window. After releasing the lock, the sash opens easily and a gas spring keeps it in a stable position. The handle also has a release function for gentle ventilation.

Gas spring

It facilitates opening the sash and holds it in a stable position up to 90°. It prevents accidental closing, increasing safety when accessing the roof.

PVC protective strip

It potects wooden elements from damage during use. A practical safeguard that extends the window's durability and increases comfort.

Universal design

The sash can be installed with left or right opening. This convenient solution simplifies installation and allows the window to be adapted to the specific room layout.

Design

The modern flashing design, developed in cooperation with the Institute of Industrial Design, emphasizes the minimalist aesthetics of the window. Three colour options — anthracite (RAL 7016), black (RAL 9005) and grey‑brown (RAL 7022) — allow for a cohesive match with the roof and accessories.

Durable protection

The P50 glazing units ensures durability and safety. The external toughened glass is covered by a lifetime hail resistance warranty. The internal P2A class laminated glass protects against injury in the event of breakage and makes it difficult to force the window during break-in attempts.
