If you are looking for a toughened glass solution that will provide strength and safety without compromising on transparency or clarity, then you have probably looked into tempered and toughened glass already. But what if you need an extra layer of protection, beyond what can be provided by a single sheet of tempered glass?
In this situation, you’re in luck – there is another type of toughened glass which combines the advantages of tempered glass and laminated glass, creating a very strong, very durable pane of glass which will not fall apart if shattered, holding itself together even when broken. This toughened laminated glass is made by sandwiching sheets of hardy, transparent polymer between sheets of toughened glass, creating a durable, clear glass that offers unmatched protection.
H2 – What is Laminated Glass?
Laminated glass is a sort of composite glass which is made of one or more layers of glass and tough, clear plastic. The glass is firmly affixed to the flexible, transparent plastic, creating a completely clear pane. If subjected to sufficient force to break the glass, the glass will break but be held together by the flexible plastic, preventing it from falling away from the frame.
In the case of toughened laminated glass, the glass layers are composed of tempered glass, making them much tougher and safer than conventional (annealed) glass.
H3 – How is Laminated Glass Made?
The first step in making toughened laminated glass is to prepare the sheets of glass that will be used. Usually, this glass is poured or rolled as normal, before going through a tempering process to make it into toughened, tempered glass.
The tempering process is most commonly carried out by heating the glass to a high temperature, before using jets of cold air to rapidly cool the outside of the pane, making it cool and contract much faster than the hot interior of the pane can. This causes differential stress patterns to form throughout the glass, putting it under immense stress. However, this stress actually works to force the glass to stay together, even under external strain. In order for the glass to break, these forces must first be exceeded, greatly raising the amount of force needed to shatter the glass.
Even then, the glass is safer than other glass types – when tempered glass shatters, it doesn’t shatter into the long, jagged shards typical of ordinary (annealed) glass. Instead, toughened glass smashes into many small, rounded, roughly cube-shaped pieces, making an injury much less likely and leading to the common name “safety glass.”
The next step in the production of toughened laminated glass is combining the tough, transparent polymer sheets with the tempered glass panes. This is done using a very powerful transparent glue, which bonds the glass and plastic along every part of their surface area. This process can be repeated for a number of layers, until the desired number has been achieved.
The new toughened laminated glass pane can then be installed!
H2 – What are the Characteristics of Toughened Laminated Glass?
Toughened laminated glass benefits from the characteristics of both tempered glass and laminated glass. This attributes confer a number of advantages onto toughened laminated glass that make it the ideal choice where safety and security are required. These characteristics include:
H3 – Strength
Where strength is required, few types of glass can measure up to toughened laminated glass. Each layer of tempered glass is stronger than ordinary glass on its own, but in a multi-layered arrangement, securely fastened to a very tough, flexible polymer sheet, the strength is more than 4 or 5 times as much as in an equivalent sheet of annealed glass.
H3 – Safety
Toughened laminated glass has a number of key advantages when it comes to safety. First off, it is very difficult to break – more than 5 times tougher than ordinary glass. This makes any kind of breakage much less likely, but if a breakage does occur, the glass will shatter into small, rounded pieces, rather than sharp shards.
In addition to this extra layer of safety, laminated glass is held together by a flexible sheet of tough plastic, which cannot shatter – this holds all the glass together even after it has shattered, stopping it falling out of the frame and preventing any spall – pieces of glass flying off as the result of an impact or breakage. This helps make toughened laminated glass one of the safest glass types available!
H3 – Soundproofing
Toughened laminated glass has excellent acoustic properties, and is well-suited to stopping the transfer of sound across the glass barrier.
H3 – Durability
If you need a tough, long-lasting glass for your home or business, toughened laminated glass is ideal for you. Well-suited for use in stairs, balustrades, dividers, doors and windows, toughened laminated glass will last for much longer than other glass types, and is hard to damage, and easy to clean and maintain!
H2 – Why Should I Invest in Toughened Laminated Glass?
Toughened laminated glass is a much more durable, much stronger, harder to break glass when compared to ordinary (annealed) glass. Requiring up to 5 times the force to smash it, this glass breaks into small, rounded pieces and does not splinter into the sharp shards usually seen with ordinary glass.
In addition to this safety feature, the glass is physically held together with a sheet of strong, clear polymer, which is flexible and cannot smash. This keeps the laminated glass together even if it is completely shattered.
