police statIon, cujik
case study
#3
With its innovative use of profiled glass, this new police station in Cujik, the
Netherlands by Dutch architect Wiel Arets might be considered an interesting
compromise between single and double façade buildings. It was the architect’s
intent to create a glass box, part of the appeal of the double façade, yet also to
provide adequate shading for the interior. By creating a cavity between two
layers of c-shaped glass, he was able to place, where desirable, an insulated
composite wall system. The building remains, however, a glass box.

Transparency is provided by windows
punched through the two layers of
profiled glass. As shown in the photo,
structure for these windows is also
sandwiched between the glass.

alternative glass types

1: glass used (translucent)
2: clear glass
The project uses a translucent glass, which is
the most common for this type of profiled
glass. The chart shows that transparent glass
is usually unavailable or available through
special order, significantly raising the
production costs.

Typical double-glazing details
Details from typical applications of this glass show
a minimal gap between each row. The 30 cm
gap used in this project, however, allowed for an
interesting play between transparency-opacity
and for the creation of homogenous exterior and
interior façades, despite varying degrees of
transparency.
