Davis Cup Halle Graz

For the Davis Cup Halle in Graz, we fabricated the largest double-skin, pneumatically tensioned thermal roof membranes we have ever produced. The venue accommodates up to 18,000 visitors and covers a total area of 9,600 m² (120 × 80 m). The lower layer of the roof membrane consists of an anthracite-colored, opaque material that deliberately reduces daylight and creates optimal conditions for lighting and event production. Notably, after the original fabrication in 1994, our customer relied on our solution again in 2024 and had us carry out the roof replacement.
