Coated and Low E Glass

Coated and Low E glass

refers to those products which have been coated with a fine layer of metallic particles. It is the reflective qualities provided by these metallic particles that give this type of

glass

it's outstanding thermal performance which results in reduced heat and cooling costs and improved occupant comfort. Recent technology has led to the development of coated products that provide low maintenance, improved scratch resistance and anti-reflective properties.

The

coating can be applied either Off-line (sputtered) via a secondary coating line or On-line (pyrolytic) which occurs during the float manufacturing process.

G.James

manufactures the Solarplus PDF 88Kb range of

off-line coated glass

suitable for commercial

windows and doors

,

curtain walls

, non-vision spandrel and overhead glazing applications.

With

recent machine upgrades and having one of the best resourced optics laboratories in Australia, G.James has the capability to design and manufacture a coating to meet your specific project requirements.

Off-line (Sputtered) Coatings

Glass

is conveyed along series of rollers and into a vacuum chamber which houses a cathode and a 'target'. The target comprises the material to be deposited onto the glass and an array of magnets behind it to create a magnetic field. A controlled amount of gas is fed into the chamber, and a negative charge is applied to the cathode, resulting in a glow discharge (or plasma) within the magnetic field region. This plasma creates positive ions which are attracted to the negatively charged target bombarding the target with such force that atoms of the target are ejected and deposited, atom by atom, onto the

glass

panel being coated.

The process

of sputtering a coating onto a

glass

surface is known as a Physical Vapour Deposition (PVD).

G.James

operates the only off-line, architectural

glass coating

facility in Australia producing a range of

coated glass

products.

On-Line (Pyrolytic) Coatings

On-line coated (or pyrolytic) glass

is produced by depositing a metallic oxide onto the

glass

surface during the manufacture of float

glass

in a process known as Chemical Vapour Deposition (CVD). An on-line coater contains a reactor wherein a 'contained' chemical reaction of the precursor chemicals occurs, leading to the deposition of a solid coating onto the

glass

surface. The thickness of the coating produced is dependent upon the reaction rate of the process.

On-line processing

results in a series of reflective coatings that are extremely hard and durable. The application process does however limit the range of available colours when compared to off-line coatings. chemicals occurs, leading to the deposition of a solid coating on the

glass

surface.
