K2 Systems S-Dome 6.15 Windbreaker Short 2004179

On a flat commercial rooftop in Hamburg, a solar installation crew secures the last row of photovoltaic modules as gusts sweep across the open expanse. To avoid heavy concrete ballast, they bolt on the K2 S-Dome 6.15 Windbreaker Short—a sleek aluminium deflector that tames airflow, cuts uplift forces, and slashes ballast requirements. This short variant fits the rear edge of the module row, integrating seamlessly with the 6.15-degree tilt of the S-Dome system.

Key specifications

• Compatible with K2 S-Dome 6.15 flat roof mounting system
• Short windbreaker for rear module row installation
• Material: Aluminium (AlMgSi0.5) with high corrosion and UV resistance
• Colour: Silver (natural aluminium)
• Function: Aerodynamic optimization and wind load reduction
• Packaging unit: 1 piece

Why choose it

Engineered for flat roof PV installations, this windbreaker reduces the need for heavy ballast, lowering structural load and installation cost. Its robust aluminium construction ensures decades of weather resistance, while the short design offers flexibility in array layout. By smoothing airflow over the modules, it enhances system stability in high-wind regions and helps meet local building codes without over-engineering the roof.

Ideal use cases

• Commercial and industrial flat roofs with ballasted PV systems
• Projects in windy or exposed locations where ballast reduction is critical
• Retrofit installations adding aerodynamic shielding to existing arrays

Good to know

This windbreaker is part of the K2 S-Dome system, designed for ballasted flat roof mounting at a 6.15-degree tilt. It is manufactured from AlMgSi0.5 aluminium, offering excellent corrosion and UV resistance for long-term outdoor use. The short variant is specifically intended for installation at the rear of the module row to optimize airflow and reduce wind uplift.
