Installation base XRD | FAKRO

Installation base XRD.

The XRD and XRD/W installation bases are designed for flat roof windows. They make it possible to raise the window above the flat roof by 15cm. Bases reduce to a minimum time of the window installation on roofs where an upstand to raise the window is required (e.g. green or gravel roofs). The XRD/A base is intended for type F & type G windows and raises their installation pitch by 3°.

• Versatility of the XRD bases allows them to be overlapped in order to achieve a higher base under the window. A maximum of two bases can be applied on top of one another. The extended element of the base, the so-called fin is used to connect the base and the roof waterproofing layer.
• The XRD/W base provides greater stability and rigidity of the upstand under the window when compared to standard XRD base, which increases the comfort of use. Three bases under one window can be combined.
• The profile of the XRD and XRD/W base is made of recycled material (grey colour) and is eco-friendly. The profile is filled inside with insulation material (polystyrene). The difference between these two bases is the application of impregnated wooden blocks in the XRD/W base. Blocks are in sizes adapted to fit chambers of the profile of the base in order to enhance its rigidity.
• Bases are adapted to standard sizes of flat roof windows. It is possible to produce bases in non-standard sizes.
• The XRD/A bases designed for type F & type G windows are fitted directly under the window, increasing its installation pitch by 3°. They consist of four wooden painted and impregnated elements creating wedge-shaped frame once assembled. They are fully compatible with the XRD and XRD/W bases. The XRD/A base is made on request.
