Description
Kozza KB5100 – French balcony aluminium H1100 mm, glass 16–17.52 mm, matt anodised

Kozza KB5100 is a complete French balcony kit designed for mounting directly onto the window frame. This flat system, made from anodised aluminium with matt anodised finish, combines minimalist design with high strength confirmed by testing. Thanks to the large glass surface with thickness 16–17.52 mm, it ensures maximum daylight penetration whilst serving as an aesthetic and safe protective barrier.
An ideal solution for installation companies carrying out modernisation projects, multi-family buildings and single-family homes — wherever a traditional balcony is impossible or uneconomical. Ready-made mounting holes and complete kit equipment allow quick installation completion without additional orders and specialist tools.

Kit contents

The kit contains everything needed for complete installation — without the need to purchase additional components:
- Two aluminium profiles with factory-prepared mounting holes
- Covers (profile cover strips)
- Glass seal (rubber, dedicated)
- End caps
Precisely positioned holes in the profiles eliminate the need for on-site drilling, which shortens installation time and minimises the risk of errors. For installation teams, this means time savings and higher finishing standards.

Application and installation
The Kozza KB5100 French balcony performs well wherever limited space or structural conditions exclude the installation of a traditional balcony — on upper floors of multi-family buildings, in modern single-family homes and when renovating existing buildings. Installation does not require significant intervention in the building structure, making it a trouble-free solution in both new construction and modernisation.
Installations — appearance after mounting


The structure confirmed by strength testing and wind load resistance guarantees many years of comfort and safe use. The minimalist aluminium profile with matt anodised finish is resistant to corrosion and weather conditions, maintaining its aesthetic appearance for years of operation.
