Patterned Double Glazed Glass

Wired glass, also known as shatterproof glass or wire glass, is a special type of glass formed by pressing a wire mesh into a semi-liquid glass ribbon during the rolling production process. Its advantages include higher strength than ordinary glass; when subjected to impact or sudden temperature changes, it breaks without falling apart and cracks without scattering, preventing small, sharp fragments from flying out and injuring people. In case of fire spreading, wired glass can maintain its structure even when heated to the point of cracking, acting as a barrier to the fire, hence it is also known as fire-resistant glass. However, one disadvantage is that during production, the wire mesh is prone to oxidation due to high-temperature radiation, potentially leading to "rust spots" and bubbles on the glass surface. Wired glass is commonly used for skylights, ceiling covers, and windows and doors that are susceptible to vibration.

• Fire Resistance: Even if broken, the wires or mesh in wired glass can hold the fragments together, making it difficult for them to fall off or shatter completely. Even when flames break through, it can block the invasion of flames and sparks, effectively preventing the spread of fire from openings. According to Article 64 of the Japanese Building Standards Law, fire doors must prevent the spread of flames. Combining wired glass with the frame of Type B fire doors allows it to be used as Type B fire-resistant material.
• Safety: Wired glass can prevent fragments from scattering. Even in the event of an earthquake, storm, or impact that causes the glass to break, the fragments are unlikely to scatter, thus reducing the risk of injury compared to ordinary glass.
• Theft Prevention: Ordinary glass is easily broken, allowing thieves to gain illegal access, whereas wired glass is not. Even if the glass is broken, the metal wire mesh remains functional, making it difficult for thieves to steal. The theft-prevention aspect of wired glass provides a sense of security.

Due to the presence of metal wires or mesh within wired glass, its integrity is significantly enhanced. It avoids complete shattering upon destruction, thereby offering fire protection and safety effects. A drawback of wired glass is its poor transparency due to the internal wire mesh, which interferes with visual effects, and the exposed metal wires at the edges of the glass are prone to corrosion. The safety of wired and mesh-reinforced glass is evident in its ability to maintain integrity upon destruction, with fragments held together by the wires, reducing harm to individuals. It can be used in skylights, roofs, interior partitions, and other situations where fragments could cause injury. Additionally, because wired mesh glass is not easily penetrated, it also serves a theft-prevention function when used for door and window glass. Mesh-reinforced glass can also be used as a secondary fire-resistant material for doors and windows. Ordinary glass easily breaks and falls apart in fires, causing air movement and spreading the fire. Although wired mesh glass may crack in a fire, it does not collapse or get penetrated due to the support of the metal wires or mesh, maintaining its integrity to a considerable extent, preventing air movement, and offering significant resistance to fire spread. Wired and mesh-reinforced glass is also suitable for earthquake-resistant applications, such as buildings with high seismic protection requirements and industrial plants with vibrations. Wired and mesh-reinforced glass improves the brittleness of flat glass, offering a cost-effective and widely used architectural glass solution.
