DUOL continues to redefine excellence in air-supported structure technology. In just October and November 2025, DUOL successfully completed six new air domes across Germany, while two additional projects are already underway — an extraordinary achievement that highlights DUOL’s remarkable production capacity, precise project coordination, and strong on-site installation support.

DUOL tennis bubble / air dome is a cost-effective and flexible means of covering tennis courts permanently or only during the winter months.

A collaboration built on trust, proven performance and more than three decades of airdome expertise.
