A

Anti- reflective glass
Surface-coated glass which minimises light reflectance and therefore shows virtually no visual reflection

Aspect ratio
This is the ratio of the longer side of a pane, to its shorter side.

C

Curtain walling
This is generally a non-load bearing aluminium facade cladding system, which forms an integral part of a building’s envelope.

D

Desiccant
Generally a silica gel-based product which is placed within the cavity spacer bar of double-glazed units; its purpose being to dehydrate, or to remove any residual moisture in the unit.

E

Energy Absorptance
The percentage of solar radiant heat energy absorbed and re-emitted externally and internally by the glass.

Effective U-value
This is the difference between the amount of heat gain and heat loss through glazing

Energy Reflectance
The percentage of solar radiant heat energy reflected by glazing.

F

Float glass
The creation of a transparent flat glass manufactured by floating molten glass on a “tin-bath” at extremely high temperature.

I

Infill panel
The glass panel underneath the handrail in a barrier that provides containment. It does not provide structural support to the main frame of the barrier.

P

Photocatalysis
This refers to the ability of a material to breakdown organic compounds on a surface using UV radiation. This is the process utilized by Saveheat Self Clean.

R

Rebate
The section of the frame surround which forms an angle into which the glass is placed and secured.

S

Self-cleaning glass/Saveheat Self Clean
This is a glass product with a photocatalytic and hydrophilic coating. The coating uses the dual-action of UV light and rain (or water) to break down organic dirt and reduce the adherence of mineral material. The glass stays cleaner for longer and is easier to clean.

T

Transom
This refers to the horizontal framing bar between glass panes. It can also be used to refer to a fanlight over a door.
