Buleet Proof glass
BULLET PROOF GLASS
Scope: Bullet proof glass is the glass that is capable of stopping different bullet calibers.
Glass thickness ranging from 18 to 60mm in multi layers of glass with PVB to withstand different kinds of ammunition fixed from different arms and distances.

Tempered Glass
The tempering process produces highly desirable conditions of induced stress which result in additional strength, resistance to thermal stress and impact resistance.
Fully tempered glass must have a surface compression of 10,000 PSI (Annealed is below 3500 PSI) and heat strengthened must have a surface compression between 3,500 and 7,500 PSI.
The basic principle employed in the heat treating process is to create an initial condition of surface and edge compression. The condition is achieved by first heating the glass, then cooling the surfaces rapidly.
This leaves the center glass thickness relatively hot compared to the surfaces. As the center thickness then cools, it forces the surfaces and edges into compression.
Wind pressure, foreign object impact and thermal stresses or other applied loads must first overcome this compression before there is a possibility of breakage.
In the heat treatment process the key procedure is application of a rapid air quench immediately upon withdrawal of hot (1200 degrees F) glass from the tempering furnace. The immediate and sustained application of an air quench produces the temper.
A quenched condition becomes stable when the glass is reduced to a temperature of approximately 400-600 degrees F.
Tempered glass is about 4 times stronger than standard annealed.
When broken, Toughened Glass shatters into small blunt - edged fragments (dice) reducing the risk of human injury
Available in thicknesses ranging from 4-19mm (¼" - ¾")
Toughened glass sheet sizes up to 1.9 metres (75") by 3.8 metres (150"). Minimum size 280mm (11").

Double-glazed glass
Insulating glass is a multi-glass combination consisting of two or more panes enclosing a hermetically-sealed air space. The most important function of insulation glass is to reduce thermal losses, which offers many advantages: lower energy consumption, perfect transparency by reducing the incidence of condensation on the warm air side and the possibility of using larger glazed areas without increasing energy consumption ...
Production:
Insulating glass is a glazed unit composed of two or more glass panes separated by spacers filled with dehydrated air or gas. The sheets are connected by a spacer, using sealants to reduce water vapour penetration. The whole unit is hermetically assembled by a secondary edge seal which gives structural robustness to the insulating glass. The spacer contains a desiccant which absorbs humidity from within the air space. The insulating glass unit (IGU) is made manually or with an automatic plant.

Glass Materials
Clear Glass
Glass is a translucent material allows light to go through. The natural of regular glass has a slight green tone in it especially when looking at its edges. The color of the green tone is determine by the thickness and the size of glass. There are 10 different thicknesses which is for different purpose of use.
2mm = 3/32", 8mm = 5/16"
3mm = 1/8", 10mm = 3/8"
4mm = 5/32", 12mm = 1/2"
5mm = 3/16", 15mm = 5/8"
6mm = 1/4", 19mm = 3/4"
- Windows normally use 3mm to 6mm thick glass
- Interior windows normally use 6mm glass which is installed by using the woodstops or u-channel
- Table Tops normally use 6mm (Someone may use 8mm). If people use it as the table top alone, usually the thickness are from 8mm to 19mm. But most people use 12mm as a standard thickness or some people may prefer to use 15mm to 19mm for luxury.
- Glass shelvings normally use 6mm to 19mm, but it depends on the size and the weight of things that people put on it.
Safety Glass
There are mainly two types of safety glass:
1. Tempered Glass
Tempering is a thermo treatment to an annealed glass. It is normally 6 to 7 times stronger glass. When it breaks, it shatters into thousands of small pieces so that any cutting injury will be reduced to minimum.
2. Laminated Glass
Laminated glass is made by sandwiching a vinyl film in between two pieces of glass. When it breaks, the film will stick the glass together so that any cutting injury will be almost eliminated. The glass are all clear glass, however, the vinyl film in between can be in clear, white, or any other colors. The laminated glass provides an endless spectrum of transparent or translucent color.
Applications for safety glass are: Doors, windows, furniture, railings, shower doors, cabinetry, etc. especially when strength is required and movable panels, ie. swing doors.
Bullet-Resistant Glass is a transparent glass panel which combines the strength and feature of tempered glass, laminated glass and polycarbonate.

Privacy glass
Privacy glass is designed by principles of polymer liquid-crystal optics. In the natural state, liquid crystal droplets are aligned randomly in the polymer and the reflective index of liquid crystal does not match that of polymer (np ≠ ne), so the incident lights are scattered, resulting in a translucent state. When an electrical field is applied, the liquid crystal droplets reorients so its extraordinary relective index matches that of polymer (np = ne), resulting in a transparent state.
Typical applications include control room and command center for govenrment facilities, executive offices and conference room, special effects for entertainment industry, exhibition, and outdoor advertisement.

Glass floor panels
Glass floor panels are increasingly popular in contemporary interior and exterior applications. Glass floor panels allow light to pass from underneath to show illumination or to allow light to brighten the space below the floor.
Guibang Glass supplies thick laminated glass floor panels to meet your most demanding requirements and you can have patterns, decorative interlayers, colors, textures and more.
