The solution took the form of a RAICO THERM+ aluminum

Alongside the large glazed areas, the transition between
the transparent and opaque areas represented a
further challenge. “Opaque sections are important in

Stéphane Kocher, Project Manager at Progin métal

performance and versatile range of applications
and practical possibilities. These metal construction
professionals constructed a façade totaling 3,600 m²,
including 3,250 m² in the form of the THERM+ aluminum
mullion-and-transom curtain wall system. This provided
the framework not only for the fixed glazing but also
for 169 FRAME+ 90 WI/WB insert elements with a
size of 1028 x 3028 mm. Of these glazing elements,
approximately 2,250 m² were transparent and some
1,000 m² were opaque. “In this project, the transition
from transparent to opaque glazing was demanding due
to the different thicknesses of glass and questions relating
to load transfer,” explains Kocher. “That is why we are so
appreciative of the economic efficiency of RAICO products
in projects like this, as well as of the company's service
and personal contact.”
