Product Information

Fakro DMG P2 Manually Operated Double Glazed Flat Roof Window

The Fakro DMG P2 Manually Operated Double Glazed Flat Roof Window is designed to bring natural daylight and fresh air into flat-roof spaces while providing reliable insulation and security. With its simple manual opening mechanism, you can easily control ventilation and adjust airflow to suit the comfort of your room. Combining practical performance with a modern appearance, the DMG P2 is well suited to both residential and commercial properties. Its secure double glazing, insulated UPVC kerb and durable construction make it a dependable choice for improving daylight and ventilation without compromising on thermal efficiency.

Easy Manual Ventilation

The straightforward manual opening mechanism makes the Fakro DMG P2 simple to operate. You can open the window when you need additional airflow and close it again when the room reaches a comfortable level. This makes it a practical option for spaces where controlled natural ventilation is important.

Secure Double Glazing

The window features a P2A laminated glazing unit designed to provide a combination of security, durability and thermal performance. It includes 4mm toughened external glass and 6.2mm laminated internal anti-burglary glass. The low-emission coating further helps to improve the glazing's insulating properties.

Excellent Thermal Performance

With a whole-window U-value of 0.92 W/m²K and a glass U-value of 1.1 W/m²K, the DMG P2 helps limit heat transfer through the roof. This can contribute to a more comfortable indoor temperature throughout the year while supporting better overall energy efficiency.

Insulated UPVC Kerb Upstand

The Fakro DMG P2 is supplied with a 150mm multi-chamber insulated UPVC kerb upstand, finished in RAL9010 white. The robust kerb provides a strong base for the window while also helping to improve thermal insulation. Its clean finish works well with a variety of modern interior designs.

Modern and Stylish Appearance

The DMG P2 combines practical performance with a contemporary look. The internal RAL9010 white PVC finish provides a clean appearance, while the RAL9005 black aluminium profile and 80mm black border around the glazing create a distinctive modern finish.

Suitable for Flat Roofs

Designed for flat roofs with pitches between 2° and 15°, the Fakro DMG P2 can be used across a range of architectural applications. Whether it is being installed in a residential extension, office, commercial property or another flat-roof space, it provides a convenient way to combine daylight and natural ventilation.

Durable and Weather Resistant

The DMG P2 is made using durable materials designed to withstand everyday exposure to the elements. Its robust construction provides long-lasting performance while keeping maintenance requirements relatively low, making it a practical choice for projects where reliability is important.

Delivery

Every order is personally reviewed by our experienced team to ensure everything is correct before dispatch. We offer delivery from as little as the next working day on selected products, so please refer to the dark blue Estimated Delivery box above for the expected delivery timeframe for this item.

We work with trusted manufacturers and specialist delivery partners to ensure your order arrives safely and on time.

Roof Tiles & Fittings:
