Glossary

a
Annealed Glasssearch for term

Refers to float glass that has undergone a heat treatment process where it has been slowly cooled to relieve the internal stresses created during its formation. This glass is not suitable for point-supported applications as it is generally not strong enough and, in the event of a breakage, would break into large shards that could cause injury.

Articulatingsearch for term

This term refers to the ability of a glass bolt to rotate in such a way that the glass can flex under load, relieving the stresses around the holes in the glass.

b
Bucklingsearch for term

Generally referred to in fin or tension truss design the glass will collapse due to compression

Bushingssearch for term

A non-metallic material placed into holes in the glass, it ensures that there is no direct contact between glass and steel. Also known as ferrules.

d
Dead Loadssearch for term

These loads are the self weight of components put on the structure like glass and the structure itself. Typically they are relatively constant throughout the structure’s life, and so they are also known as Permanent loads.

Deflectionsearch for term

The distance that a structural member (such as glass) displaces when under load. This is an important factor to consider in design to manage the stress in the glass.

f
Facettedsearch for term

A surface that appears curved, made of flat pieces of glass.

i
IGUsearch for term

Stands for Insulated Glass Unit. Another term for double glazed glass. Other terms could include Sealed Glass Units.

Inner litesearch for term

A term generally used in laminated or double glazing. Refers to the glass located on the interior of the building.

Interlayersearch for term

The material that holds two pieces of glass together to form laminated glassConsists of two or more pieces of glass held together with an interlayer. In the event of a breakage, the interlayer holds the shards of glass together. Tempered laminated glass is required by most codes for overhead applications such as canopies and is recommended for situations where people could be injured by falling glass.. Materials include PVB (Polyvinyl Chloride), SGP (Sentry Guard Plus®) or liquid resins.

Live loadssearch for term

These loads, sometimes referred to as probabilistic loads, include all the forces that are variable within the object’s normal operation cycle not including construction or environmental loads. They include (but are not limited to) wind, snow, seismic, human loading and storage.

n
Neoprenesearch for term

A synthetic rubber that Stella uses as a gasket with our glass bolts to provide a “soft connection” between the glass and the support structure.

o
Outer litesearch for term

Term generally used in laminated or double-glazing. Refers to the glass located on the exterior of the building.

t
Tempered Glasssearch for term

Glass that has been heat treated and processed to increase its strength to about 4 times that of annealed glassRefers to float glass that has undergone a heat treatment process where it has been slowly cooled to relieve the internal stresses created during its formation. This glass is not suitable for point-supported applications as it is generally not strong enough and, in the event of a breakage, would break into large shards that could cause injury.. As well as being stronger, this glass is also safer in the event of a breakage as it breaks into small cube shaped pieces versus annealed glass which breaks into large, dangerous shards. Tempered glassGlass that has been heat treated and processed to increase its strength to about 4 times that of annealed glass. As well as being stronger, this glass is also safer in the event of a breakage as it breaks into small cube shaped pieces versus annealed glass which breaks into large, dangerous shards. Tempered glass is generally reccomended for point-supported glass systems. is generally reccomended for point-supported glass systems.

w
Wind Loadsearch for term

Loads created by positive or negative wind pressure (the blowing on or sucking in on glass).
