Many locations require the installation of laminated or tempered Glass.
Safety glass types
Before the development of safety glass, regular Glass, also known as annealed Glass, was the most common type available.
Because of the rising number of injuries caused by regular Glass, most buildings must now conform to current requirements requiring the installation of safety glass replacement in high-risk locations vulnerable to human impact whenever Glass Replacement is needed.
It is the most often used safety glass in residential and commercial structures: in glass doors, panels adjacent to doors, low-level windows, and other locations where humans may come into contact with the Glass.
Laminated Glass comprises two or more sheets of annealed or toughened Glass glued together with a PVB plastic interlayer.
Various sizes and thicknesses are available, laminated in clear, grey, or bronze annealed laminate.
When laminated glass cracks, the PVB interlayer between the two sheets of Glass keeps the Glass together, preventing big harmful fragments from coming out.
Other benefits of laminated Glass include the suppression of 99% of transmitted UV radiation, enhanced sound insulation capabilities, and superior security that inhibits access by thieves or intruders.
Although laminated Glass meets all safety criteria for current standards, tempered Glass is required in specific applications.
Tempered Glass breaks into hundreds of little harmless pieces when cracked. While this is a significant safety feature, the primary reason for its usage is its temperature resistance and improved strength of up to five times that of annealed Glass.
Tempered Glass is often used in the following applications:
- Assemblies with no frames
- Shower enclosures
- Doors made of Glass
- Glass at a low level
The disadvantage of tempered Glass is that it develops a tiny corrugated distortion during the toughening process, which is noticeable under close examination.
Another issue is that it cannot be cut or changed after the toughening process; as a result, each panel is cut and processed to produce a unique product that, in most situations, cannot be utilized anywhere else.
Furthermore, the whole sheet disintegrates when toughened glass fractures, leaving an open passage, reducing the security and safety advantages.
