Fakro DXF-D U6 Non-Opening Flat Roof Window

The Fakro DXF-D U6 Non-Opening Flat Roof Window is a high-performance daylighting solution designed to bring plenty of natural light into modern residential and commercial buildings. With its fixed, non-opening design, it is ideal for areas where ventilation is not required but excellent insulation, security and a clean architectural appearance are important.

High-Performance Triple Glazing

The DXF-D U6 features high-quality triple glazing designed to provide excellent thermal performance while helping to create a more comfortable indoor environment. The glazing incorporates 6mm toughened external glass and laminated internal anti-burglary glass rated P2A or higher, providing a strong and secure solution for flat roof applications. The window achieves a whole-window U-value of up to 0.70 W/m²K, helping to minimise heat loss and support better energy efficiency throughout the year. Its advanced glazing construction also helps reduce external noise, making rooms quieter and more comfortable.

Fixed Design for Added Security

As a non-opening flat roof window, the Fakro DXF-D U6 is designed for spaces where ventilation is not needed. The fixed construction provides a secure installation while helping retain indoor heat. With no opening mechanism to maintain, it also offers a straightforward, low-maintenance solution for bringing natural daylight into your property.

Insulated and Durable Construction

The window is supplied with a 150mm insulated UPVC kerb upstand finished in RAL9010 white PVC. The multi-chamber construction provides strength, rigidity and effective thermal insulation, helping the window deliver dependable performance over the long term.

Modern Architectural Appearance

The Fakro DXF-D U6 combines practical performance with a contemporary appearance. Its RAL9005 black profiles, subtle grey-tinted glazing and darkness-effect glazing edge create a sleek finish that works particularly well with modern architectural designs.

Designed for installation on flat roofs with pitches between 2° and 15°, the DXF-D U6 offers flexibility across a variety of building projects. Its fixed design makes it particularly suitable for rooms where the main priority is natural daylight, thermal performance and security rather than ventilation.

Roof Tiles & Fittings:

We recommend ordering an additional 10% of roof tiles to allow for any breakages that may occur during delivery or handling. Roof tiles are naturally fragile, and having a few extra on site helps prevent delays and ensures your roofing project can be completed without interruption.
