What is the thickness of safety glass?
Laminated glass is constructed of two 1.8–2.3 mm thick sheets of glass with a very thin layer (typically 0.76 mm thick) of polyvinyl butyrate (PVB) in between. The PVB layer makes the windshield shatter-proof, which is essential for the safety of the driver and the front passengers.
How thick should glass be for windows?
The vast majority of residential windows use Single Strength glass which is 3/32” thick. For larger windows, Double Strength, or 1/8” thick glass may be required. For extremely large residential window it may be necessary to use 5/32” or 3/16” thick glass to assure adequate wind-load resistance.
What is the thinnest safety glass?

Tempered glass can be from 1/8" to 3/4" thick. Tempered glass is about four times stronger than a lite of annealed glass of the same size and thickness. The only characteristic of the annealed glass affected by tempering is its bending or tensile strength. Tempering increases the tensile strength of glass.
How thick is laminated safety glass?
The thickness can vary from 0.60 to 0.90+ mm, depending on the glazing pocket or user preference. The use of stronger interlayer materials, other than the standard polyvinyl butyral (PVB), makes laminated glass stronger and stiffer compared to standard glass and other types of safety glass.
