ESTER Casement Window
ESTER: the slim frame window
Uncompromising and forward-thinking Italian design meets contemporary styling and modern energy efficiency credentials.
ESTER is the latest innovation from ES Finestra, creators of slim and non-frame aluminium windows. A window system with a thin 44mm frame that brings attention to where it’s deserved: the glass, light, and the view. The window is specially designed to allow full transparency on the outer side of the glass, meaning no frame is seen, allowing up to 40% more light than traditional windows. On the inside, a number of different framing materials and colours are available, from weathered steel, wood, aluminium, and more.
Systems
ES Finestra's ESTER glazing system can be specified in a number of systems that are designed to work interchangeably with other ES Finestra models.
