A special work of art has been erected in the desert of Qatar: “Shadows-travelling-on-the-sea-of-the-day”. It consists of 22 round roofs with a diameter of no less than 10 metres. The roofs are made of lightweight composite: a combination of fibreglass and vinylester.
Mirrors are mounted on the underside and the whole thing stands firmly on a curved metal tube. However, the mirrored underside makes it seem as if the roof is balancing on a narrow ring. The production of the composite elements took place in our factory in Lelystad, the assembly in Qatar was carried out by a local contractor.
The size of the individual roofs required a special production method: not in one piece, but a construction of four separate elements. For this purpose, we designed our own mould for each element, in which the materials were placed. This was combined with the vinylester using the vacuum injection method.
