Chicken wire, invented in 1844 by British ironmonger Charles Barnard, was originally designed to keep chickens from fleeing their coop. However, its use expanded to include glass doors, with the first instance of chicken wire glass manufactured in 1894 by the Pilkington Group, headquartered in St. Helens, United Kingdom. The wire mesh in the glass serves multiple purposes, including strengthening the glass, improving heat resistance, and preventing the glass from falling out of the frame in the event of cracking or breakage. This makes chicken wire glass an effective barrier against intruders, fire, and even certain types of wildlife.
| Characteristics | Values |
|---|---|
| Strengthening component | The wire mesh strengthens the glass by holding it in place and preventing it from falling out of the frame, even if it cracks under thermal stress. |
| Fire resistance | Chicken wire glass is fire retardant as the wire mesh prevents glass shards from falling, stopping the spread of flames. |
| Security | The wire mesh makes it harder for intruders to break in by preventing them from reaching through the glass to unlock the door. |
| Aesthetic appeal | Chicken wire glass is valued for its beauty and can be made with various designs, such as a maize-like pattern or as a clear polished plate. |
| Ultraviolet protection | Chicken wire glass intercepts 99% or more of incoming ultraviolet rays, protecting furniture near windows from discoloration caused by sunlight exposure. |

Chicken wire strengthens glass doors
Secondly, chicken wire enhances the fire resistance of glass doors. In the event of a fire, the wire mesh keeps glass shards from falling, reducing the spread of flames. This property of chicken wire-reinforced glass makes it particularly useful in service elevators and institutional settings, where fire safety is a priority.
Chicken wire also provides protection against pests and animals. It can be used to prevent rodents, such as rats, squirrels, and chipmunks, from digging and entering enclosed spaces. Additionally, it can deter larger animals like coyotes and goats from breaking through or chewing on wooden structures.
While the presence of the wire mesh may give the impression of added strength, it is important to note that wired glass may be weaker than unwired glass due to the incursions of the wire into the glass structure. Wired glass can also cause heightened injury during fractures due to the wire amplifying the irregularity of breaks.
Despite this, chicken wire-reinforced glass doors remain a popular choice for security and fire resistance, especially in schools, banks, museums, and other buildings where safety is a priority.

It holds cracked glass in place
Chicken wire glass is a type of glass that has a grid or mesh of thin metal wire embedded within it. It was invented in 1894 by the Pilkington Group, headquartered in St. Helens, United Kingdom. The process of creating chicken wire glass involves sandwiching steel wire mesh between two separate ribbons of semi-molten glass and then passing the "sandwich" through metal rollers that squeeze the wire and glass together.
One of the main benefits of using chicken wire on front doors is that it holds cracked glass in place. If the glass cracks, the wire prevents it from falling out of the frame, even under thermal stress. This feature also makes it harder for intruders to break in by reaching through the broken glass to unlock the door from the outside.
In addition to security benefits, chicken wire glass is also valued for its fire-resistant properties. The wire mesh keeps glass shards from falling, preventing flames from spreading. This makes it ideal for use in service elevators and institutional settings to prevent fire ingress and provide protection against heat and hose streams.
While wired glass may be weaker than unwired glass due to the incursions of the wire, it is still widely used for its ability to resist fire damage and provide security against intruders.

Chicken wire is fire-resistant
Chicken wire, also known as hex mesh, is made from thin, flexible galvanised steel wire twisted into hexagonal patterns. It was invented in 1844 by British ironmonger Charles Barnard, who was inspired by cloth-weaving machines to create a mesh fence to contain chickens.
Chicken wire is often embedded in glass to increase its fire resistance. The wire mesh keeps glass shards from falling, preventing flames from spreading. It is also heat-resistant, with a higher melting point than materials such as plastic or wood, allowing it to withstand heat for longer before failing.
However, it is important to note that chicken wire's fire resistance is limited. When heated, the zinc coating on galvanised wire can vaporise, releasing harmful fumes. Additionally, the wire mesh embedded in glass may amplify the irregularity of fractures, leading to heightened injury risks.
Chicken wire is also used in doors and windows for security and pest control. It can prevent intruders from reaching through broken glass to unlock doors and provides a physical barrier against pests when buried underground.

It is a burglar-proof solution
Chicken wire glass is an effective burglar-proof solution for front doors. The wire mesh embedded within the glass strengthens the glass, making it harder to break. Even if the glass cracks or breaks, the wire holds the shards in place, preventing intruders from reaching through to unlock the door. This feature also makes it more difficult for intruders to break in by providing an additional physical barrier.
Chicken wire glass also offers fire-resistant benefits. The wire mesh helps to prevent the spread of flames by holding glass shards together, reducing the risk of fire damage. This fire-resistant property is particularly valuable for service elevators and institutional settings, where fire safety is a priority.
In addition to its practical advantages, chicken wire glass can also be aesthetically pleasing. It can be designed with various patterns, such as a maize-like design, ribbed, rough-rolled, or clear polished plate. The wire is thoroughly covered, preventing rust or corrosion and adding to its visual appeal.
The use of chicken wire glass in front doors provides a sense of security and peace of mind for homeowners. It serves as a physical deterrent to potential intruders and reinforces the strength of the glass. This added layer of protection can make it significantly more challenging for burglars to gain entry, contributing to a safer home environment.
While chicken wire glass offers enhanced security and fire protection, it is important to note that it may not be suitable for all applications. In some cases, it may cause heightened injury due to the wire amplifying the irregularity of fractures. As a result, its use in schools and other institutional settings has declined, replaced by modern impact-resistant glass alternatives.

Chicken wire is aesthetically pleasing
While the practical benefits of chicken wire on front doors are clear, the addition of chicken wire to glass can also be aesthetically pleasing. Chicken wire glass can be made with a variety of designs, including a maize-like design, ribbed, rough-rolled, or as a clear polished plate. The wire is so thoroughly covered that rust or corrosion is highly unlikely, and it can be customized to different dimensions, with a thickness of 1/4, 3/8, or 1/2-inch, a width of up to 40 inches, and a length of up to 100 inches. Chicken wire glass is valued for its unique appearance, and its ability to intercept 99% or more of incoming ultraviolet rays, protecting furniture from discoloration caused by sunlight exposure.
Chicken wire has been used for more than just functional purposes. Its rustic and primitive aesthetic has been incorporated into interior design, such as in cabinet doors, window frames, and wall decor. The wire mesh pattern adds a farmhouse or country-style charm to various home decor pieces.
Chicken wire's visual appeal is not limited to the interior of the home. In 1894, glass-enclosed rooftops became trendy, and innovative glass manufacturers, including the Pilkington Group, began to embed chicken wire within glass. This wire mesh glass provided safety and fire-resistant benefits, but it also contributed to the overall design and style of the glass rooftops.
The process of creating chicken wire glass involves sandwiching steel wire mesh between two ribbons of semi-molten glass, resulting in a cohesive and unified appearance. The wire is embedded at a specific temperature to ensure the cohesion between the metallic netting and the glass, creating a smooth and integrated surface.
Chicken wire's versatility extends beyond its practical applications. Its simple yet distinctive pattern enhances the visual appeal of various architectural and decorative elements, making it a unique and aesthetically pleasing choice for those seeking a blend of functionality and style.
