The role of wired glass

Wired glass is a type of safety glass. There is wire, iron wire or stainless steel wire inside. In this way, when the glass is cracked, the broken glass will not fly or collapse, causing personal injury. Wired glass is also called fireproof glass.

Wired glass is also called shatterproof glass. It is made by heating ordinary flat glass to a red-hot softened state, and then pressing preheated iron wire or wire mesh into the middle of the glass. Its characteristics are excellent fire resistance, it can block flames, it will not explode when burned at high temperatures, and it will not cause fragments to hurt people when broken. In addition, it also has anti-theft properties, and the barbed wire will stop the glass from being cut. Mainly used for roof skylights and balcony windows.

Wired glass is also called shatterproof glass and steel wire glass. During the calendering production process, a wire mesh is pressed into a semi-liquid glass ribbon to form a special glass. The advantage is that it is stronger than ordinary glass. When the glass is subjected to impact or drastic changes in temperature, it will break without being chipped or cracked without falling apart, preventing small angular fragments from flying out and injuring people. For example, when a fire spreads and wired glass explodes due to heat, It can still maintain a fixed state and play the role of isolating fire, so it is also called fireproof glass. The disadvantage is that during the production process, the wire mesh is easily oxidized by high-temperature radiation, and yellow and bubbles like "rust spots" may appear on the glass surface. Wired glass is often used in skylights, ceilings, and doors and windows that are susceptible to vibration.

Even if the wired glass is broken, the wires or nets can hold the fragments, making it difficult to chip and break. Even when the flame breaks through, it can block the intrusion of flame and fire powder, and has the effect of preventing the spread and spread of burning from the opening.

According to Article 64 of the Japanese Building Standards Act, fire doors are stipulated. The outer wall opening must prevent the spread of flames. Using wired glass combined with the frame of Class B fire doors can be used as Class B fireproof materials.
