Product overview
Eaves windows are frameless “up and over” glass structures designed to follow the line of a roof and create uninterrupted glazing from vertical wall to overhead glass. Using the Invisio structural glazing system, these installations can be designed with no visible supports or frame, creating a glass box rooflight effect with clean architectural detailing.
The system uses specialist strengthening interlayers within the vertical glass, allowing the panels to carry the load of the glass above. This makes it possible to create frameless eaves glazing, roofline windows, glass box extensions and architectural roof glazing with a clear, minimal finish.
Sieger Systems supplies and installs frameless eaves windows and structural glass systems across London, Buckinghamshire, Berkshire, Oxfordshire, Hertfordshire, Surrey, Bath, Bristol and Somerset.
