GEALAN-LUMAXX®:
More glass, less frame
Traditional systems look heavy with bulky profiles. Lumaxx revolutionizes design for more natural light (+25%).
STV® Technology:
Invisible stability
The secret to slim profiles is STV®. The glass is bonded directly to the sash, making it a single load-bearing element.
- Unbeatable rigidity: No more sashes "sagging" over time.
- Large dimensions: We create large glass surfaces with total safety.
- RC2 Protection: Bonded glass is nearly impossible to pry open.
Maximum Glass Surface:
From Slim Profile to Hidden Sash
