The XRD installation base is designed for the type F flat roof window – it allows to raise the window above the roof by 5.9" (15cm). It reduces to a minimum time required to install the window in roofs where it is necessary to raise the window (e.g. green or gravel roofs). Design versatility of the XRD installation base allows overlapping of frames one on top of the other in order to achieve higher base for the window. Up to two frames can be overlapped. Lengthened frame element, the so-called fin allows connection of the base with water insulation of the roof. Profile of the XRD base is manufactured from the recycled material (grey colour), hence the product is eco-friendly. The profile is filled inside with insulation material (polystyrene), thus ensuring very good insulation parameters. The base is adjusted to standard sizes of flat roof windows. Custom sizes avaialble to match non-standard dimensions of the type F flat roof windows.

In case of the construction of a higher base it is necessary to cut protruding part of the fin around perimeter and overlap bases one on top of the other.
