CFRP Carbon Fibre Roof, Glass Walls With a Beam-Free Design

key features

Composites elements: 44 CFRP panels, each 23m long, with one centrepiece.

Why composites: carbon fibre panels enabled the construction of a roof without internal supports, reducing weight, minimising individual components, and providing a visually striking solution.
Weight
The carbon fibre roof weighs 80 tons, representing a 51% reduction in mass compared to traditional materials. This allowed for the creation of a roof with no internal floor support, a feat impossible with traditional materials.
Cost
While the raw material cost of CFRP is higher than traditional materials, the design freedom, weight savings, and other benefits significantly reduced downstream costs. The project required only 45 panels and 38 support brackets, compared to 452 panels and 1,800 brackets with traditional materials. The roof was assembled and lifted as a single unit, reducing installation time to just 2.5 hours—a timeline unachievable with traditional methods.
Strength
Thanks to the high strength-to-weight ratio of carbon fibre, the supports and infrastructure were optimised for the lightweight roof, providing advantages not possible with conventional materials.
Durability
The carbon fibre composite panels meet all weather and environmental requirements, ensuring long-term performance.
Maintenance
Minimal to no maintenance is required over many years, as is typical with composite parts.
LCA/Environmental Impact
Composites have a lower CO₂ footprint and are fully recyclable. In the future, the carbon fibre can be recovered and repurposed for other high-value structural applications instead of being disposed of in landfill.
