ATRIUM
It is possible to install VELUX roof windows in flat roofs (roof
pitches form 0° to 15°) to produce an atrium type eect. However,
this installation requires special cover and flashing components
that must be ordered as special products.
Cover and flashing components are based on a kerb construction
similar to VELUX Flat Roof Kerb ECX.
The kerb for the atrium is not part of the VELUX product pro-
gramme and should be made on site. Certain dimensions must be
respected, see drawings opposite.
The dimensions of the kerb vary depending on chosen window sizes
and frame distance.
Before installing the windows, ensure that the construction is
structurally stable.
Install the windows according to the installation instructions for
the window. Supplementary instructions are enclosed with the
special flashing.
