Glass that has been gradually cooled during manufacture, this is glass that has not been tempered or strengthened and can be cut and processed.
A small, rough beveling that has been performed to the edge of the glass to smooth out imperfections and make it safer to handle.
A barrier that has been placed between a hand rail and the floor, typically used in fencing or staircases.
The material used to hold glass in place (usually timer or aluminium) between the framing and the rebate.
A sloped edge applied to an object, generally used for mirrors on glass.
Sometimes referred to as a "case," this is a wholesale unit of glass containing multiple full sized sheets.
Polyisobutylene, a compound used for sealed double glazed units, preferred for its resistance to moisture.
Computer Assisted Drawing. A drawing or diagram made using a special program that contains precise measurements, angles, details and anything else of importance. These can be given to a machine such as a waterjet to replicate precisely.
Computer Numeric Control. A type of machine that takes an instruction, or a CAD drawing and then executes those commands, such as for cutting glass or templates.
Abbreviation for 'cut to size.'
Sometimes referred to as a "block," this is a wholesale unit of glass containing multiple full sized sheets.
When two pieces of glass are utilized in a single opening, this can be done either as a hermetically sealed unit or through the use of special framing with two separate pockets. Both have their own distinct advantages and uses.
An object or materials ability to radiate or emit energy.
Where the edges of a glass panel are ground down to make a flat, uniform surface along the edge. No polishing is applied, but the edges are smooth and safe to handle.
Where the edges of a glass panel are ground down to make a flat, uniform surface and a polish is applied to give the edges a clear shine.
Glass made using the 'float' process. This is where all glass starts it's journey as the float process is the current industry standard. It's name comes from how the glass mixture is floated on a hot bed of molten material, this helps to give the finished sheet a uniform thickness and high quality finish.
The process of installing glass into it's framing, pocket or opening. Be it a window, door, partition or any other such use.
A type of Low E coating that is incredibly hard. Applied to the face of the glass, the coating is suitable for uses in single glazed Low E applications and can be difficult to damage.
A process in which a piece of glass is heated up to incredible temperatures for a prolonged period of time. This process removes any imperfections left over inside the glass panel and is typically done after toughening, although it is not required.
A lesser form of toughening, the glass is treated in a similar manner but instead of shattering into small pieces, the glass will instead break all the way to the ends. Can be useful for places where toughening alone might not comply, but it will not comply itself as a safety glass. Heat soaking renders heat strengthening redundant.
Something that has been sealed in such a way so that air may not pass between the interior and exterior.
A type of glass consisting of two or more individual pieces of glass that have been joined together with a special interlayer.
The amount of visible light transmitted through a piece of glass, displayed as a percentage of total light.
Low Emissivity. A type of glass designed with a specialized coating applied to one face where it aids in reducing heat gain or loss, such that the glass acts as a much better insulator than regular glass. Used as an exterior application, most modern buildings have some form of Low E glass on their facade.
High quality float glass that has been manufactured in such a way that it contains much less iron than regular float. Iron is what gives glass its green tinge and while most of the time this is unimportant, low iron glass works well for use in splashbacks, display cabinets or buildings where a more neutral colour is desired.
A type of small bevel performed to both faces of a glass on the edges or corner in order to remove the sharpness of an edge or edges.
A single pane or piece of glass that hasn't been laminated or double glazed with any other piece of glass.
A vertical member used in framing or construction.
Poly Vinyl Butyral. The material most laminated glass is made using.
A property of a material that shows its level of sound reduction measured in dB.
The ability of a piece of glass to reflect light. Measured in percentage, this shows how much light is reflected back into a space or back out to the exterior.
SentryGuard Plus. A special type of interlayer owned by SentryGuard. This is used for high security or structural applications as the interlayer is incredibly rigid and will hold its shape after a breakage.
Solar Heat Gain Coefficient. The ratio of transmitted and absorbed energy from the sun that passes through the glass as compared to having no glass at all.
Glass that has been processed in such a way (such as toughened or laminated) that it complies with the definition set out in AS2208. It has it's name because we deem these glass types much safer for use than those that aren't. Typical application is for things such as doors, shop fronts, fencing, balustrades or anywhere human impact is a risk.
A direct ratio between light trans and SHGC, showing the tradeoff between better SHGC but lower light transmission. A higher number is better.
A special type of glass polish performed by a special machine that allows the process to be done to shaped edges rather than just straight lines.
A type of incredibly high performing Low E coating applied to a glass. It earns it's name due to it's fragility. Because of this, soft coat Low E products are provided ONLY as a double glazed unit, however the benefit of their performance heavily outweighs any drawbacks.
A measure of the total percentage of solar energy that is reflected back to the outside of the glass.
The total percentage of solar energy that is transferred through a piece of glass.
The special material used in double glazing (either our special foam spacer or aluminium) that surrounds the outer perimeter of the two pieces of glass and keeps them at the predetermined distance from each other. This is usually filled with a desiccant and then sealed with polyisobutylene.
Glass that has been processed through a special glass furnace. The toughening process is similar to how steel is hardened in that it heated up to incredibly high temperatures and then has its outer layer rapidly cooled. This process builds incredible tension between hot inner part and the now cooled outer layer increasing the durability of the glass.
Glass that has been manufactured to have a level of diffusion through it such that the vision is not totally clear.
A horizontal member used in framing or construction.
The total measure of heat transmission between the inside and outside of a piece of glass. Displayed as watts per m2 per degree celsius, a lower number indicates better insulation and thereby, better performance.
Ultra-Violet. The EMF range just above visible light. This is the first series of wavelengths that are ionizing (able to strip electrons away from their nucleus) and has well known ill effects such as being a leading cause of cancer and also contributes to fading the colour of furniture or clothing.
The total percentage of energy in the UV spectrum that is transmitted through a piece of glass.
Mirror which has a sheet made from a vinyl material applied to the back of the glass already. The vinyl holds in the event of a breakage not unlike a laminated glass. This is what the overwhelming majority of mirrors are made from.
A special type of CNC machine that uses a high powered stream of water to cut through materials. Useful for cutting shapes out of the middle of a piece of glass, such as for a powerpoint.
