Glass mullion system
A glass mullion system is a type of glazing system that can be used to construct vertical glass curtain walls, canopies, skylights, and so on, allowing large areas of glazing to be created whilst maintaining a high level of transparency.
It is formed by sheets of tempered glass held in position by clamps and joined to the glazing by a structural silicone sealant or by metal patch plates. The glass mullions are typically suspended from the head structure above and can span distances of more than 20 m or more, transferring wind, snow and self-weight loading back to the primary structure.
