Annealed glass
Clear Glass
Annealed (float) glass is produced by melting sand, soda ash, dolomite, and limestone together to produce a continuous ribbon which flows from a furnace and “floats” over a bed of molten tin, which is then carefully cooled to “anneal” the glass.
Ultra Clear Glass
Ultra clear glass has an additional process included to clear glass process, to remove the iron content from sand used when making glass, giving it a clearer purer colour. Ordinary annealed glass has a green hue to it, which comes from the iron content. Ultra clear glass provides maximum transparency and clarity by providing a crystal-clear glass. When painted, ultra clear glass represents particular light colours more accurately than traditional clear glass.
Tinted Glass
Tinted glass is made using the same process as annealed glass. The tint is added using metal oxides to the float glass process. The thicker the glass selection, the darker the tone will appear. The addition of the oxides to tint the glass does not affect the basic properties of the glass except for lowering the amount of visible light and solar energy transmittance.
Tempered Glass
Toughened or tempered glass is a type of safety glass. It is made by heating annealed (float) glass uniformly through a furnace to temperatures exceeding 600° C. The annealed (float) glass is then transferred to the quenching chamber of the furnace where it is rapidly cooled.
This process increases the compression forces on the surface and the tension forces inside the glass, which gives toughened glass four to five times more strength than ordinary annealed (float) glass of the same thickness, combined with much greater resistance to impact.
Heat-Soaked Glass
Toughened Glass can sometimes spontaneously break; the reasons can be many. The main cause determined by leading experts are that there are microscopic traces of Nickel Sulphide (NiS) inclusions within the glass which can be activated during the heating process in producing tempered glass
At Hawk Glass, the heat soak treatment is a quality control process carried out by placing the toughened glass panels inside an oven chamber and subjecting the glass to a prolonged temperature of up to 270°C in a controlled cycle to accelerate nickel sulphide expansion. This causes glass containing nickel sulphide inclusions to break in the heat soak chamber, thus reducing the risk of potential breakages after installation.
Heat Strengthened Glass
Heat strengthened glass is a type of safety glass. It is made by heating annealed (float) glass uniformly through a furnace to temperatures exceeding 400°C. The annealed (float) glass is then transferred to the quenching chamber of the furnace where it is rapidly cooled.
Heat strengthened glass is approximately 2 times stronger than ordinary annealed glass but is not as strong as toughened glass. This glass, when broken, will break into comparatively larger pieces than the toughened glass .
Laminated Glass
Laminated glass is produced by bonding two sheets of glass together with an interlayer known as PVB (Polyvinyl Butyral). Due to the interlayer, laminated glass does not shatter when broken, reducing the risk of injury. Laminated glass is also known for its UV protection, it can block 99% of all ultra violet light which helps to protect carpets, curtains and furniture.

IGU Build Up
Glass
Glass in an IGU is used to provide natural light and maintain internal temperature conditions and protection from outside conditions.
Spacer Bar
Glass panels in an IGU are separated by a ‘spacer’. Spacers can be found in a number of materials, each of which has an effect on the performance of the IGU. They are often made of aluminium or an insulating plastic composite known as warm edge spacers..
Warm edge spacers get their name because they are more insulating and not as conductive as aluminium spacers. Current available materials are aluminium, steel, stainless steel, thermoplastic, and plastic.
Gas fill
To improve the performance of an IGU, gas filling is an option provided by manufacturers. Inert gasses such as Argon and Krypton are used in place of just air in the internal cavity of the unit.
Sealants
Sealants are used in the construction of an IGU in two stages. A primary seal is used to fix the glass panels to the spacer bar, and a secondary seal is used to seal the outer edges of the complete unit. The sealants purpose is to prevent moisture penetration into the unit.
Primary sealants are often used in conjunction with aluminium spacer bars and act as a barrier to stop thermal transfer from the two glass panels touching it. Warm edge spacers are often applied with a self-adhesive primary seal, and due to their material makeup are already far less conductive than their metal alternatives.
The secondary seal (outer seal) is always required when constructing an IGU. It provides structural strength to the IGU edge. Secondary sealants generally come in the following variants; hot melt butyl, two-part polysulphide, two-part polyurethane and silicone.

Performance Data Definitions
Hot Air always moves towards cold air. By reducing the loss of heat from the warm side to the cold side of the window, IGU’s can reduce the heat loss in cold weather, or vice versa.
VLR: The percentage of visible light that is reflected from the glass surface(s).
VLT: Expressed as the percentage of visible light that is transmitted through a glass type
SHGC: Solar Heat Gain Coefficient. The proportion of directly transmitted and absorbed solar energy that enters into the building’s interior. The lower the number the better the glass is able to exclude solar radiation.

SOUND PERFORMANCE OF IGUs
If you require sound proof glass, IGUs have many benefits compared to single glaze windows, one of which is its sound insulating ability. Changing the thickness of glass used in the IGU or combining a laminated glass panel can greatly improve the insulating properties of the IGU.
Compare the sound insulation characteristics of the following configurations:
Configuration 1:
• This would have the least amount of sound insulation.
• 6mm Clear Float window has a rating of 31 (Rw)
Configuration 2:
• This would have a better sound insulation, but not the best.
• 6mm + 12mm spacer + 6mm IGU has a rating of 34 (Rw)
Configuration 3:
• This build up uses glass panels of different thicknesses. Due to the change of thickness the frequency dampens significantly when passing through, giving improved acoustic performance.
• 10mm + 12mm spacer + 6mm IGU has a rating of 36 (Rw)
Configuration 4 – Optimal IGU Configuration:
• This build up provides even better performance in sound insulation and a thinner and lighter IGU. The build-up uses an acoustic laminate glass to provide better acoustic performance and an overall thinner and lighter IGU.
• 6mm + 12mm spacer + 6.5mm IGU has a rating of 38 (Rw)

Frosted Glass:
Generic term used to describe glass whose surface tends to diffuse or scatter incident light and has a “frosted” appearance. Frosted glass is produced by a variety of methods including etching with chemicals, using abrasives, engraving, application of ceramic inks or decals and by attaching or incorporating translucent films.
Sand Blasted: Glass is produced by using high-velocity air to spray a stream of hard, abrasive particles against one or both surfaces giving the area a frosted appearance.
Acid itched: Glass that has been chemically treated with an acidic material, such as hydrofluoric acid, to produce a surface finish that will diffuse transmitted light, reduce glare, and has a frosted appearance.
Digital Printed Glass
Digital art is a visual feature created on a computer in digital form. The digital file can be purely computer generated or taken from another source, such as a scanned photograph or an image drawn using vector graphics software. Digital art can then be transferred by printing onto glass, inter-layers or other films and substrates.
Colored Glass
Colored glass contains metal oxides added to the raw glass, batch created glass with color extending through its mass. For example, cobalt produces blue glass, chromium – green, silver – yellow, and gold – pink. Visible light transmittance of colored glass varies from 14% to 85%, depending on the hue and thickness. Thicker the glass darker the color shade.
Lacquered Back Painted Glass
A coating applied to glass that completely covers the surface is virtually opaque and available in various solid and metallic colors. In some applications the glass can be partially coated with clear areas for design. Typical applications for painted glass are wall cladding, spandrel glass and furniture.

Self-cleaning glass
With the latest technology, this dream of self cleaning glass is entirely possible. Our Nano Glass Coating is a transparent shield that is applied to any glass or ceramic surface, giving it a hard and durable water repellent and “self-cleaning” surface. Dirt and other deposits cannot cling to the treated glass surface and either wash away easily or can be simply cleaned with water and a cloth
What happens is that our glass coating makes the glass water repellent and the water can’t get into the pits and valleys of the glass. In fact the water will sit high on the surface and the droplets will tend to curl up and quickly roll away. Dirt, grime, slime, calcium and other deposits will not be able to embed or cling strongly to the surface and will wash away easily.
This is why it is known as self cleaning glass – it does practically clean itself.
