Centre glazed narrowline windows place the glass in the centre of the aluminium frame profile, creating an aesthetically balanced look with ultra-slim sightlines that maximise natural light and unobstructed views.
The narrow profiles deliver a contemporary, architecturally refined appearance, making them the preferred choice for projects where visual elegance and maximum glass area are priorities. Face-matched mullions, transoms, and frame profiles ensure a consistent, seamless look across the entire facade.
At Smart Doors & Windows, we supply and install centre glazed narrowline systems across Melbourne for residential high-rises, commercial fitouts, healthcare facilities, and educational institutions.
