Description
Kozza KB5100 – complete French balcony aluminium H1100 mm, glass 10–11.52 mm, matt anodised

French balcony Kozza KB5100 is a complete set of aluminium profiles in a flat system, designed for mounting directly on the window frame. Thanks to its minimalist construction and matt finish (anodised), it allows installation companies to offer clients modern, aesthetic protection for open windows — without the need to interfere with the building façade.
The system supports glass with thickness from 10 to 11.52 mm and maximum dimensions of 1000 × 1100 mm (width × height). The large glazed area allows maximum natural light into the interior, whilst test-proven resistance to wind and loads guarantees years of safe use.
Quick installation without complications

Profiles are supplied with precisely pre-drilled holes, which significantly reduces installation time. Ready-made elements eliminate the need for additional drilling and machining on site — standard mounting tools are sufficient.
Kit contents:
- 2 aluminium profiles with pre-drilled holes
- 2 cover strips (covering strips)
- 1 glass seal
- 2 end caps
- 2 spacer washers
Installation instructions — step by step
The photographs below show the successive stages of kit assembly: from component layout, through inserting the seal into the profile (green markers show mounting points), to the finished, assembled kit.

The profile is mounted directly to the window — without interfering with the wall construction. The system ensures aesthetic finishing from the external side thanks to cover strips and glass seal.
Application
French balcony KB5100 is ideal for:
- Multi-storey buildings on upper floors — secures opening balcony doors
- Modern single-family houses — as a minimalist façade element
- Modernisation and renovation of older buildings — installation does not interfere with wall construction
- Wherever maximum interior lighting is important without a traditional balcony
Final result — installations


Matt, anodised aluminium harmonises with both light and dark window frames, giving the façade an elegant, modern character.
