Closed Cavity Façade (CCF) System 

Closed Cavity Façade (CCF) System

Bespoke Closed Cavity Façade (CCF) systems, delivered by Staticus is engineered to meet demanding performance requirements in thermal insulation, acoustic control, and long-term durability. It features a double-skin assembly with a sealed cavity that is supplied with subtle overpressure of dehumidified air . This prevents condensation and dust accumulation and allows integrated solar shading to operate reliably throughout the year with minimal maintenance.

Jointly developed façade solution for high-performance projects

The system has been developed in collaboration with Wicona, a long-term technical partner with a proven track record of CCF implementations across Europe. Together, we have adapted the system for efficient production, reliable on-site installation, and long-term serviceability, backed by tested performance data and maintenance protocols.

 

Key features and benefits of our CCF system

  • High thermal insulation

    CCF system achieves thermal transmittance values as low as Uw = 0.54 W/m²K, with glass U-values of 0.5 W/m²K, contributing to improved energy efficiency and reduced heat loss. Because the cavity is closed and pressurized, air inside acts as a thermal buffer.
  • Effective acoustic control

    Tested performance of up to Rw = 48 dB significantly reduces external noise transmission, supporting acoustic comfort in noise-sensitive urban environments.
  • Low-maintenance cavity system

    A sealed cavity flushed with filtered, dehumidified air prevents condensation and internal contamination. No manual cleaning is required inside the cavity.
  • Integrated shading with simplified maintenance

    Venetian blinds are installed within the protected cavity. Only the exterior and interior glass surfaces require cleaning, unlike traditional double-skin façades with four surfaces. Blinds have a longer service life and require less maintenance, as they are shielded from wind, rain, dust, and pollution. Shading devices and coatings remain clean and free from mechanical wear. Internal blinds are unaffected by wind loads, with no ice, snow, or dirt buildup – ideal for cold or dusty climates.
  • Adaptability to complex geometries

    The façade system accommodates varying design requirements, including curved elements, angled transitions, and setbacks, ensuring architectural consistency across complex building forms.
  • Energy-efficient

    The dry-air system requires approximately 8.6 kWh/m²/year (based on 5,223 m² of glazed area), supporting energy targets for buildings aiming for BREEAM Excellent or equivalent certifications

Via Vika - First CCF Application in Northern and Eastern Europe

Via Vika is the first building in Northern Europe to implement a Closed Cavity Façade (CCF). Staticus delivered the complete façade package – design, testing, production, and installation, covering over 2,000 units. Read more.

Via Vika’s technical ambition and execution also earned industry recognition. The project was shortlisted for the SFE Façade Design and Engineering Awards. Read more.

This project advanced high-performance façade systems in the Nordic region, showcasing how precision-engineered, low-maintenance CCF technology meets energy, acoustic, fire safety, and environmental demands in architecture. The system has since been further developed and applied in other signature projects, including the K8 tower in Stavanger.
