Insulating glass (IG) more commonly known as double glazing (or double-pane, and increasingly triple glazing/pane), consists of two or three glass window panes eparated by air space or gas filled space to reduce heat transfer across a part of the building envelope.
DGU: Double Glazed Unit: it contains only 2 panels of glass with Aluminum spacer in between. The gap may contain 100% air or may contain 90 % Argon gas for higher performance
Multi IGU: it contains 3 panels of glass with 2 aluminum spacer, usually use this type for higher thermal performance. The gap may contain 100% air or may contain 90% Argon gas for higher performance.
Laminated Glass
Laminated Glass
Is a type of safety glass that holds together when shattered. In the event of breaking, it is held in place by an interlayer, typically of polyvinyl butyral (PVB) or ethylene-vinyl acetate (EVA), between its two or more layers of glass. The interlayer keeps the layers of glass bonded even when broken, and its high strength prevents the glass from breaking up into large sharp pieces.
This process does not significantly affect the strength of the glass but it does improve the safety of the glass as laminated glass typically remains intact and retains some strength even after fracture. For this reason, it is possible that future practice may allow higher stresses for such glass
SINGLE INTERLAYER LAMINATION
This type has single interlayer and only 2 panels of glass
MULTI INTERLAYER LAMINATION
This type has 2 interlayers or more and more than 2 panels of glass
Tempered Glass
Tempered Glass
Is a type of safety glass processed by controlled thermal or treatments to increase its strength compared with normal annealed glass. Tempering puts the outer surfaces into compression and the interior into tension. Such stresses cause the glass, when broken, to crumble into small fragments instead of splintering into jagged shards as plate glass (a.k.a. annealed glass) does.
Fully Tempered
In this type the glass will gain its maximum strength, and when broken the fragments will be very small
Heat Strengthened Glass
In this type the glass will gain less strength than full tempered glass and will make bigger fragments when broken. both heat strengthened and fully toughened have a surface compression induced by temperature increase and sudden quenching. the existence of the surface compression means that it must be overcome by load before any surface tensile stress is achieved. the magnitude of the surface compression is of the order of 3 to 6 times the typical stress values used in annealed glass design. this leads to a similar strength increase without any effect on the glass stiffness and deflections.
Frameless Glass
Is single glass units, usually installed internally e.g. Partitions and Fins.This glass may com in different thickness from 8mm, 10mm, 12mm, 15mm, 19mm
Decorative Glass
Sandblasted Glass
Glass can be decorated by sandblasting the surface of a piece in order to remove a layer of glass, thereby making a design stand out. Items that are sandblasted are usually thick slabs of glass into which a design has been carved by means of high pressure sandblasting. This technique provides a three-dimensional effect but is not suitable for toughened glass as the process could shatter it
Digital Printed Glass
It is one of the most common decorative glass technologies that uses ink to print any desirable picture or pattern over the glass. This technology can be used in single, double or laminated glass
Georgian Bar Glass
It has Aluminum bars attached to the aluminum spacer in between the glass panles
