Sliding sashes
Variations of available sizes (max W × max H, mm), as well as the number (2-3-4-5-6-7-8) and configuration of sliding sashes in the ALU-GLASS glazing system:


Recommendation: We suggest glazing the entire patio with sliding glass walls — offered at the same cost as fixed panels. In the summer season, the panels can be fully opened with ease, allowing natural airflow to circulate freely, helping to regulate temperature and create a more comfortable outdoor environment.
Custom designs and project-specific dimensions are available upon request.
