Product Description

This FAKRO modular double glazed flat roof window has been designed to maximise the amount of natural light that enters a room without compromising on thermal efficiency. The FAKRO flat roof window can be opened manually, and is available in a number of different sizes in order to create the perfect daylight solution for your home.

This FAKRO double glazed modular flat roof window should be installed on flat roofs with a pitch between 2 and 15 degrees, ensuring that there is a minimum of 2 degrees to allow rainwater to flow off the surface of the roof window. The modular double glazed flat roof window is manually operated, meaning that it can be opened manually with a 2.2m control rod to provide ventilation when required.

Maximise daylight

The double glazed flat roof window from FAKRO has been carefully designed to maximise the amount of sunlight that enters the room. The specially designed shapes of the sash and frame ensure that the flat roof windows feature up to 16% greater glazing area compared with other manufacturer’s windows of the same size.

Minimise heat loss

Another key feature of the FAKRO manual modular flat roof window is the glazing. The flat roof window offers P2 laminated double glazing, which includes a layer of glass on the outside, with an argon gas cavity, as well as a 6.2mm internal glass pane with a low emission coating.

The glazing is combined with a uPVC upstand, which has a multi-chamber design. This combined with the double glazing creates an incredibly thermally efficient flat roof window.


Due to the manual operation, the FAKRO modular flat roof window is a source of natural ventilation as well as natural daylight. By opening the FAKRO modular double glazed window, you create a flow of fresh air which improves the internal comfort of the environment.

Ease of installation

This modular quad glazed flat window is supplied with a kerb for installation. The window is also supplied with a specially profiled covering material, which sits beneath the drip cap of the frame. This helps to create a tight connection between the roof window and the roofing material.

If required, the fixed modular flat roof window can be installed on an additional XRD base. This allows the flat roof window to be installed on green roofs and in other situations where the window needs to be lifted slightly above the surface of the roof.

Questions & Answers


Is 800x800 the full window size or the opening?


This is the roof opening size.


Can you open it up and get out?


No, this product is not suitable as an access hatch I am afraid.
