Designed by Frankfurt-based architect Prof. Christoph Mäckler, the terminal extends over 1,500 meters and features a modular layout focused on future growth and sustainability. The first section spans 55,000 square meters and accommodates up to five million passengers annually. The design relies on natural light and integrates utilities discreetly, creating open, energy-efficient spaces that reduce reliance on artificial lighting during the day.

 

Largest flat roof insulation project with Multipor from Xella

A key element in achieving the terminal's sustainability goals is the innovative use of Multipor flat roof insulation from Xella. The mineral-based insulation boards were selected for their non-combustibility (A1 fire rating), compressive strength, and eco-friendly properties. Made from sand, lime, cement, and water, the boards are recyclable and free of fibers and pollutants. Their excellent thermal conductivity (0.045 W/mK) contributes significantly to energy savings.

 

In total, around 4,400 cubic meters of insulation were used to cover 25,000 square meters, making it the largest flat roof project in Multipor’s history. Xella provided custom gradient plans for water drainage, and the installation was carried out efficiently thanks to strong collaboration with the roofing contractor. This setup ensures durability, weather resistance, and the ability to support various loads, from walkways and gravel to green roofs and HVAC (heating, ventilation, and air conditioning) systems.

 

Sustainable construction for the future of air travel

Terminal 3 is scheduled to begin operations in 2026. When fully expanded, it could serve up to 25 million passengers annually. A newly built SkyLine train line connects terminal 3 with the existing terminals over a 5.6 km track, ensuring seamless integration with road, rail, and even bicycle traffic. From materials to mobility, terminal 3 stands as a model for forward-thinking, sustainable airport development.
