New Rhine-Neckar-Arena

Description

The new Rhine-Neckar-Arena in Sinsheim has been recently completely finished. A stand roofing system made of technical textiles round off the newly built stadium and offers protection for more than 30.000 spectators. CENO TEC GmbH, an enterprise from Greven-Germany, produced and installed the roofing system within only a few months.

High-tech materials for functional use
A total area of 19.500m² is covered by technical textiles. The amount of material used is around 60.000m². For optical and acoustic reasons not only the upper side, but also the lower side of the steel supporting structure is covered with the membranes. Two different membranes were used, depending on the function. The upper membrane that faces the outside is intended to protect against the weather whilst at the same time allowing light through onto the stands. 56 roof fields, each with 5 support arches, are covered with architectural membranes made of translucent PVC-coated polyester fabric (type III) having a dirt-repellent fluoropolymer coating. This varnish is more weathering resistant than traditional varnishes. The lower membrane that faces the stands is in-tended to have an optically calming effect. A fine-meshed PVC-coated polyester screen fabric is used for this. A total of 750 steel frames are finished with semi-transparent material.
Another special feature of the roofing system is the fact that the 750 covered steel frames were produced in accordance with a joint model such that they can be displaced in order to achieve a closed homogenous ceiling. The architect's design has been consequently implemented with many technical individual solutions.
The roof edge glazing planned for the inside of the stadium is also part of CENO TEC’s scope of delivery. Around 6.000m² of polycarbonate panelling will provide for protection against the weather and translucence around the entire circumference of the playing field.
