​For some time now, metal roofs have gained more and more importance in architecture as they allow attractive roof geometries and therefore more design options. The sports trained in the Cambridge Sports Centre require different hall ceiling heights. To optimally balance the different height requirements, the 5,000m² roof was arched 

The top of the steel beams was covered with one layer of trapezoidal steel sheet and a vapour barrier, followed by LINITHERM PAL OSB sloped-roof insulating elements with a thickness of only 135mm.
