Georgian Wired Glass is sometimes also known as 'Safety Glass', although this name isn't particularly accurate (more on this later). Essentially it is glass manufactured with wire mesh embedded into it to prevent it from shattering and breaking whilst also increasing its fire rating.
What glass is considered a safety glass?
Safety glass is a type of glass made in such a way that it is less likely to cause injury if it breaks. Tempered glass is one of the most well-known forms of safety glass, but it's not the only one. Safety glass can also be laminated, engraved, and made of wire mesh.
Is wired glass safe?
It is less than half as strong as ordinary glass and extremely dangerous upon impact. “Most people believe the purpose of wire in glass is safety and security, but it isn't,” says Drew Gilliand, Associate Director of Physical Activity and Recreation Services, at the University of Oregon.
How can you tell if glass is safety glass?
To identify whether your property has laminated or toughened glass, you will need to look for a printed kitemark code in the corners of the glass:
- BS EN 14449 – laminated glass.
- BS EN 12150 – toughened glass.
What are the different types of safety glass?
Two types of safety glass are heat-strengthened and tempered. Heat-strengthened glass is cooled at a rate faster than regular annealed glass. Tempered glass, in turn, is cooled at a faster rate than heat-strengthened glass. Another way to strengthen glass is to use more than one lite of glass in the application.

Definition of wire glass
: glass with wire netting embedded in it during manufacture to reduce the probability of its shattering when cracked by shock or by heat. — called also safety glass.
Is safety glass same as toughened glass?
Toughened glass, also known as tempered glass after its method of production, is a type of safety glass that is five times stronger than annealed and laminated glass of the same size and thickness.
Is all safety glass marked?
According to section 7 of BS 6262-4:2005, the safety glass needs to be permanently marked so that it is clearly visible after installation. By marking glass, consumers and Building Control Officers have confidence that it conforms to standards and regulatory requirements.
How do you tell if glass is tempered or laminated?
You can tell if you have laminated glass by viewing it on edge. Laminated glass has a visible interlayer. It also sounds different from annealed or tempered glass when knocked on (but it may require an ear attuned to the difference).
How do you tell the difference between glass and tempered glass?
Examine Its Edges
Normally, tempered glass has completely smooth edges due to the extra processing it goes through, while other types of glass usually have scuffed or ridged edges. If the edges of the glass are exposed, run your fingers along them.
Why is wired glass not used now?
Despite its traditional status as a form of “safety” glass due to its internally reinforced structure, wired glass is increasingly being viewed as both obsolete and hazardous due to the serious injuries it can inflict upon impact, as well as the development of viable alternatives.
Is wired glass fire rated?
Wired Glass is a monolithic glass. It offers reliable, integrity only, fire-resistant glazing in a range of applications, including doors, screens and overhead glazing. It can also be used in a variety of internal and external applications for vision or privacy purposes.
Do they still make wired glass?
Alternatives to Georgian Wired Glass
The US banned wired glass in 2006 and Canada has removed wired glass from its national building standards. With new products such as Plasiax™ Wire offering a safer alternative whilst retaining your visual heritage, it could be time to leave Georgian Wired Glass in the past.
Is laminated glass the same as safety glass?
Both laminated and tempered glass are considered safety glass because they meet the requirements set forth by various code organizations that enable them to be used in the situations above.
Is safety glass toughened?
Toughened glass is sometimes known as tempered glass or safety glass. The glass is four times as strong as standard annealed glass and if broken, shatters into small granular pieces that don't have sharp or jagged edges.
Can glass be both laminated and tempered?
Finally, there is a way to make glass both laminated and tempered. The process can be difficult and expensive, but the outcome is worth it. Many car manufacturers are switching to a tempered, laminated glass.
Is tempered glass bullet proof?
Tempered glass is made to withstand some damaging forces, but it won't be able to protect you against any kind of bullet fired from a gun (except maybe a small BB gun).
What should be stamped on safety glass?
The markings should include: ∎ The manufacturer's name or trade mark ∎ The product number for the type of glass * ∎ The impact performance classification e.g. 1, 2 or 3 to BS EN 12600 or A, B or C to BS 6206.
Is all toughened glass stamped?
Toughened glass is required to be marked with BS6206a, this can take the form of the circulaur BS Kitemark or a simple line. It is also possible that the glass is laminated, which will also satisfy the requirement for safety glass, if so it is unlikley to be marked.
Do all windows need safety glass?
Safety glass should be fitted in all doors and other windows or glazed areas that are lower than 800mm from the floor level. Glass panels less than 250mm wide can be fitted with 6mm glass or laminated glass instead of toughened glass. In doors where the glass comes within 1500mm from floor level.
What type of glass is used in car windows?
Auto glass is either tempered or laminated. The glass usually used for the front and rear door windows and the rear window are made from tempered glass, the windshield is made from laminated glass.
What thickness is safety glass?
The most common form of safety glass (and the lowest cost) is 4mm toughened glass. This glass is used for almost all residential safety glazing and 4mm toughened comes in a large range of obscure patterns as well as the energy saving glass – Pilkington K glass.
Where do we use wired glass?
Wired glass is used in windows and partitions of schools, institutions, public buildings, government offices, hotels, etc. Wired glass is generally installed in windows of fire escape routes of the structure, to gain time for evacuating people in case of fire emergencies.
What is wired glass and why it is used?
Wired glass was an early form of safety glazing, as the wire would catch much of the glass and prevent it from falling. The glass was also frequently treated with a fire retardant to prevent the glass from breakage if exposed to high temperatures and the wire to hold it together in case it did break.
Which type of glass is used in wired glass?
Wired glass typically has a grid size of around 12.5mm and is used as a low-cost fire resistant glass in which the wire holds the glass in place if high temperature causes it to break.
