Project detailsx

Surface:15,000 m2 roof area
Material: Duplicor® biobased fire-resistant composite
The Van Gendt Hallen: five monumental factory halls from the late 19th century in Amsterdam Centre-East. The Netherlands’ first steam trains and diesel engines were built here and these halls were the heart of Amsterdam’s industry and trade for over 100 years.
After years of standing empty, they were saved from demolition and are now being renovated with love and entirely according to modern and sustainable requirements. We are proud that with our new bio-based and fire-resistant composite Duplicor®, we were able to make an important contribution to this renovation: the striking steam hoods.
As much as 15,000 m2 of Duplicor® was processed into roof elements, giving the Van Gendt Hallen back its iconic look.
The load-bearing capacity of the original monumental structure could not take much additional weight. Yet the architect and client wanted to see the original ‘steam hoods’ back on the roof and also apply PV panels for renewable energy output.
With its unique lightweight fire-resistant properties, Duplicor® brings the solution for roof replacement on listed buildings. The prefabricated elements for the steam hoods span over several “old wooden and steel” roof trusses. The façade elements are self-contained elements supported on foundations. The exterior and interior finishes are so tight that no further finishing was required after assembly.
The structural composite façade elements have dimensions of 12.50 x 3.50 m, with a thickness of 300 mm. The total facade area covers 5650 m². These large dimensions saved a lot of assembly and labour costs and enabled a very efficient construction of the façade.
Duplicor® is a fully bio-based composite (building) material. Manufactured from a 100% natural resin, virtually non-flammable, lightweight, CO2-saving and also affordable.
With Duplicor®, the full potential of composite can finally be exploited in the construction world. Not only for new construction projects, but also for (large-scale) renovation projects. From facades to roofs and from floors to balconies: many kinds of applications are possible.
