Due to the large dimensions and the special shape of the roof shells, their production required a lot of specific knowledge and skills. For example, the production techniques of the composite elements are based on the standard production methods for hulls of sailing ships. Holland Composites has extensive experience in (composite) shipbuilding, plus the right knowledge, craftsmanship and tooling in-house, so this special assignment was in good hands with us.
The wing-roofs consist of a curved construction of several complex roof shells, varying in thickness from 200 to 300 mm. The total roof consists of 75 unique elements that are glued and finished on site. These free-supporting sandwich wing-roofs have a maximum span of 31 metres, with one of the points hanging freely 9 metres.
The segments are assembled upside down and provided with prefabricated reinforced strips. They were then checked again for the correct dimensions, finished and reinforced with gauze and filler. The bottom was given a fire resistant layer and the top an infrared resistant layer. As a final step, the shells were flipped over and finished evenly on all sides.
