Glass balcony systems transform balconies into four-season living spaces. However, choosing the right system is important.

Folding Glass Balcony

Glass panels open by folding with a hinge mechanism. The entire balcony can be opened, offering up to 90% opening ratio.

Advantages: - Wide opening ratio - Entire balcony can be opened - Aesthetic appearance - Easy cleaning

Considerations: - Requires reinforced hinges in windy areas - Slightly higher cost compared to sliding systems

Sliding Glass Balcony

Glass panels slide on a rail system. Panels stack on top of each other and gather at one side.

Advantages: - Economical solution - Simple mechanism, low maintenance - More stable in windy areas

Considerations: - Lower opening ratio compared to folding (60-70%) - The area where panels gather cannot be used

Double Glazing Option

Double glazing (thermal glass) can be applied to both systems. Double-glazed models increase thermal insulation in winter, providing energy savings.

How to Decide?

  • **Wide opening** → Folding system
  • **Budget-focused** → Sliding system
  • **Winter use priority** → Double glazed models
  • ICS Alüminyum's technical team recommends the most suitable system based on your balcony measurements and intended use.
