Fakro DMF-D U6 Manually Operated Flat Roof Window

The Fakro DMF-D U6 Manually Operated Flat Roof Window is a practical, high-performance solution for bringing natural daylight and fresh air into modern buildings. Designed with manual operation, it gives you simple control over ventilation while maintaining excellent thermal insulation. It is well suited to both residential and commercial spaces where comfort, energy efficiency and ease of use are important.

Manual Operation for Better Ventilation

The manually operated design makes it easy to open the window whenever you want to introduce fresh air into the room. Smooth and reliable operation allows you to control ventilation without relying on an electrical system, making the DMF-D U6 a straightforward choice for everyday use.

High-Performance Triple Glazing

The Fakro DMF-D U6 features triple glazing with toughened external glass and laminated anti-burglary internal glass rated P2A or higher. This glazing combination provides a balance of thermal insulation, durability and security while allowing plenty of natural light into the room. The entire window achieves a U-value as low as 0.70 W/m²K, helping to reduce heat loss and support energy-efficient performance throughout the year.

Comfortable and Quieter Interiors

The advanced glazing also provides sound insulation of up to 34dB (-1, -3). This helps reduce external noise entering through the roof, creating a more comfortable indoor environment for homes, offices and other occupied spaces.

Durable Insulated Construction

The window is supplied with a 150mm multi-chamber UPVC kerb upstand finished in RAL9010 white PVC. This robust construction provides strength and rigidity while contributing to the window's overall thermal performance and long-term durability.

Modern Architectural Appearance

The Fakro DMF-D U6 combines practical performance with a contemporary aesthetic. Its RAL9005 black profiles and dark-edge glazing effect create a sleek, modern finish that works well with a variety of architectural styles.

The DMF-D U6 is designed for installation on flat roofs with pitches between 2° and 15°. This makes it suitable for a broad range of residential and commercial projects, whether you're adding daylight and ventilation to a home, office or other modern building.

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.
