Classification of fireproof glass
Fireproof glass (English name: Anti-fire Glass, also known as Fire-resistan glass) is mainly used to control the spread of fire or smoke during fire prevention. It is a measure-type fireproof material, and its fireproof effect is evaluated by fire resistance.
Classification of Fire-resistan glass by structure
Composite type
It is composed of two or more layers of glass sheets with one or more layers of water-soluble inorganic fireproof glue interlayer.
Fireproof principle: When a fire occurs, the glass facing the fire will quickly burst after encountering high temperature, and its fireproof glue interlayer will foam and expand about ten times in succession, forming a hard milky white foam-like fireproof glue board, which effectively blocks the flame and isolates high temperature and harmful gases. The finished product can be edged, punched, and cut with a different size.
It is suitable for fireproof doors and windows in rooms, corridors, and passages of buildings, as well as fireproof partitions and fireproof partition walls in important parts; when used for external windows and external curtain walls, the design plan should consider the combination of fireproof glass and PVB laminated glass.
Single-layer type
Single-layer fireproof glass is a fireproof glass with a single-layer glass structure.
Fire protection principle: When a fire occurs, it maintains fire-resistant integrity for a certain period of time, blocks open flames and toxic and harmful gases on the fire-facing surface, but does not have thermal insulation and heat insulation effects.
Suitable for exterior curtain walls, outdoor windows, skylights, smoke-blocking vertical walls, fireproof glass frameless doors, and partition walls without insulation requirements.
Injection type
It consists of two layers of glass original sheets (three layers of glass original sheets can also be used for special needs), and is sealed with special flame-retardant strips on all sides. The fireproof glue injected in the middle is transparent jelly after curing and is bonded to the glass as a whole.
Fire protection principle: After encountering high temperature, the transparent jelly-like fireproof glue layer in the middle of the glass will quickly harden to form an opaque fireproof and heat-insulating board. While preventing the spread of flames, it also prevents high temperature from being transmitted to the back of the fire. This type of fireproof glass not only has fireproof and heat-insulating properties, but also has outstanding sound insulation effects and can be processed into an arc shape.
Applicable to fireproof doors and windows, building patios, atriums, shared spaces, and fireproof partition walls in computer rooms.
