Double glass plates have a satin finish inside and a clear finish outside with glass thickness 3.0 + 2.5 mm. Perimeter frames are white lacquered aluminium with a white PVC inner frame and overall depth matching standard 8 cm glass blocks.
Fresh, controllable airflow – with an easy and secure opening system
A manual opening mechanism allows the inner closure to be operated for variable airflow while preserving the double-glass assembly. Inner closure attaches to the outer side, enabling ventilation without removing glazing elements.
Adjustable ventilation lets rooms breathe when needed while maintaining security. Simple operation makes airing a brief task rather than a project.
Durable, low-maintenance installation – with white lacquered aluminium frames and a white PVC window frame
Perimeter frames use white lacquered aluminium for UV resilience, while the window frame is made from white PVC that resists weathering. External and internal protective films simplify handling during installation.
Long-term resistance to sunlight and minimal upkeep reduce follow-up maintenance. A robust frame combination keeps appearance tidy without ongoing treatment.
Straightforward replacement of glass blocks – with 8 cm depth matching traditional blocks
Overall depth equals the standard glass block thickness of 8 cm, designed to occupy the space of two 19 x 19 x 8 cm glass blocks. Windows can be mounted vertically or horizontally for flexible orientation.
Direct-fit dimensions avoid reworking the wall opening in most cases. Orientation options suit wider openings or taller arrangements depending on wall layout.
