4.38-42.3mm safety laminated glass with CE & ISO & AS/NZS2208:1996

What is laminated glass? 
Laminated glass is a type of safety glass that holds together when shattered. In the event of breaking, it is held in place by an interlayer, typically of polyvinyl butyral (PVB) or ethylene-vinyl acetate (EVA), between its two or more layers of glass

Where to use laminated glass?
Laminated glass is normally used when there is a possibility of human impact or where the glass could fall if shattered and also for architectural applications
Skylight glazing and automobile windshields typically use laminated glass
In geographical areas requiring hurricane-resistant construction, laminated glass is often used in exterior storefronts, curtain walls and windows

Structure
There are several laminated glass manufacturing processes:
1. Using two or more pieces of glass bonded between one or more pieces of adhesives, such as PVB or EVA, using heat and pressure
2. Using two or more pieces of glass and polycarbonate, bonded together with aliphatic urethane or EVA interlayer under heat and pressure
3. Interlaid with a cured resin or EVA
Each manufacturing process may include glass lites of equal or unequal thickness

Specification
A typical laminated makeup is 2.5 mm glass / 0.38 mm interlayer / 2.5 mm glass
This gives a final product that would be referred to as 5.38 laminated glass
