The glass fin (mullion) is the original backup structure first introduced by Pilkington over 40 years ago. Today, it is still the most widely specified support member in structural glass design.
These fin supported systems exploit the full potential of glass as a structural material while providing support for the Pilkington Planar™ facades and allowing maximum transparency.
The glass fin system uses monolithic or laminated fully tempered glass fins as a means of support to transfer wind loading to structure. Various "moment" and "pin" type connections can be used to transfer loads to the structure in different ways.
