Fakro XRD Additional Installation Base

Fakro XRD Additional Installation Base

The Fakro XRD Additional Installation Base is designed to provide extra height, insulation and flexibility when installing compatible Fakro flat roof windows. It is particularly useful for green and living roofs, as well as roof constructions where additional build-up height is required. The XRD base provides a practical way to raise the position of a flat roof window while maintaining strong thermal performance. Its lightweight construction and compatibility with several Fakro flat roof window ranges make it a useful addition for a variety of roofing projects.

Adjustable Installation Height

Each XRD installation base provides 150mm of additional height, helping accommodate thicker roof constructions and green roof systems. For applications requiring greater height, up to two XRD bases can be stacked, providing additional flexibility during installation. This allows the window height to be adjusted to better suit the individual requirements of the roof build-up.

Excellent Thermal Insulation

The XRD Additional Installation Base is filled with polystyrene insulation and provides a U-value of 0.4 W/m²K. This helps reduce heat transfer through the installation and supports the overall thermal efficiency of the flat roof window system. The insulated construction is particularly useful where maintaining good energy performance is important.

Made from Recycled Materials

The XRD base is manufactured using recycled materials and has a grey finish. This provides a more sustainable option for increasing the height of a flat roof window while maintaining a durable and practical construction. Its lightweight design also makes the base easier to handle during installation.

Compatible with Multiple Fakro Flat Roof Windows

The Fakro XRD Additional Installation Base is designed to work with a range of compatible Fakro flat roof windows, including:

• FAKRO DXF
• FAKRO DMF
• FAKRO DEF
• FAKRO DXC
• FAKRO DMC
• FAKRO DEC

This compatibility makes the XRD a versatile solution for projects using different models within the Fakro flat roof window range.

Ideal for Green and Living Roofs

Green and living roofs can require additional build-up height to accommodate the roof structure, growing medium and vegetation. The XRD installation base provides a convenient way to raise the flat roof window above the surrounding roof construction. It can also be useful for thicker roof systems where a standard installation height is not sufficient.

Roof Tiles & Fittings:
