Glass for SchoolsGlass used in schools

Schools serve as both places of learning and shelters. AGC’s glass technology combines daily safety with functionality in case of emergencies.

Schools are not only places where children and students learn, but they are also used as evacuation centers in times of disaster and as places for local communities.

Schools are required to be safe, secure, comfortable, and eco-friendly buildings and facilities. What kind of glass is best suited for schools, and how does AGC technology play a role?

Question1What kind of glass is needed in schools as places for students to learn?

In schools where lots of energetic, playful students gather, the first thing to consider is “safety”.

The side facing the playground needs glass that won't break even if hit by a ball, and the side facing the corridors needs glass that won't scatter sharp fragments if students bump into it.

In addition, it is desirable to use glass that does not scatter fragments in the corridors that serve as evacuation routes for students in the event of an earthquake or other disaster, and in the gymnasium that serves as an evacuation area.

The most commonly used type of glass that “does not break even when hit by a ball” is “tempered glass.” As its name suggests, it is approximately three times stronger than ordinary glass, making it resistant to breaking. Even if it does break, the fragments form into small granular pieces.

Laminated glass is often used as “glass that does not scatter fragments”. As there is a special film between the two panes of glass, even if the glass breaks due to a student bumping into it or an earthquake, the fragments will stick to the film and not scatter, preventing serious injury.

AGC glass is helping to prevent injuries and accidents at schools.

Ordinary glass

If ordinary glass breaks, the fragments are sharp and there is a risk of serious injury.

If laminated glass breaks, it is safe because the fragments do not scatter.

Question2How can you tell if the glass in your school is safety glass?

If the glass used in your school is tempered or safety glass, there will be a sticker or mark on the lower right-hand corner of the glass.
Please check at your school.

Question3What other functions are needed besides safety?

It is also important to “maintain a comfortable learning environment”.

On the south side, where the sun shines during the day, or on the side facing the school grounds, glass with a UV-cut function protects students from glare.
In winter, glass that keeps the feet warm and prevents discomfort even when sitting by the window is ideal.

AGC glass not only achieves this ideal, but also achieves “eco” at the same time.
Comfortable glass can reduce the amount of air conditioning used, which in turn leads to energy conservation.

AGC's “Eco Glass for Schools” is the ideal glass for schools that achieves safety, comfort and eco-friendliness.

Question4School gymnasiums are often used as evacuation centers for local residents in the event of earthquakes or typhoons, but what kind of glass is needed for an evacuation center?

AGC's “Eco Glass for Schools” is also suitable for school gymnasiums used as evacuation centers.

Preventing injuries, accidents and secondary disasters!

Even if the glass breaks in an earthquake or typhoon, it is important that “the fragments do not scatter”.

If broken glass were to scatter in evacuation shelters, there would be a risk of injury and accidents, and the possibility of further danger due to rain and wind entering the shelters.

In order to prevent such situations, it is very important to prevent glass from scattering.

Maintaining a comfortable environment as much as possible!

In the event of a disaster, it is possible that the amount of air conditioning used will be limited, so it is necessary to have glass that can maintain a comfortable room temperature.

The same “safety, security and comfort” as in schools is also desired for the glass used in evacuation shelters.

The more you know, the more you realize the great contribution AGC's glass and technology make to society.

You can see that AGC's advanced glass technology is being developed to make our lives better, safer and more comfortable.
