A glazing system where glass panels are supported at discrete points rather than along their edges, typically using mechanical fixings through holes drilled in the glass. This creates minimal visual interruption and allows for large expanses of glass.
From 'point' (discrete location) and 'fixed' (attached), terminology developed in the 1980s as glass technology advanced to allow drilling and point loading. The technique emerged from curtain wall innovations.
The Louvre Pyramid uses point-fixed glazing with over 600 glass panels held by just four point fixings each - the entire pyramid appears to float above the courtyard! This technique inspired countless glass atriums and skylights that seem to defy structural logic.
