fire proof glass ,fire rated glass

There are mainly five kinds of fireproof glass, one is laminated composite fireproof glass, the other is wired fireproof glass, the third is special fireproof glass, the fourth is hollow fireproof glass, and the fifth is high-strength single-layer cesium potassium fireproof glass.

 Structure type
It is divided into fire-resistant laminated glass, thin-coated fire-resistant glass, single-piece fire-resistant glass and fire-resistant wired glass. Among them, fireproof laminated glass can be divided into composite fireproof glass and perfusion fireproof glass according to the production process characteristics.

Compound
It is composed of two or more layers of original glass sheets with one or more layers of water-soluble inorganic fireproof glue interlayers.
Fire prevention principle: When a fire occurs, the fire-facing glass will burst soon after encountering high temperature, and its fireproof glue interlayer will foam and expand about ten times successively, forming a hard milky white foam fireproof glue board, which can effectively block the flame and isolate high temperature and harmful effects. gas. The finished product can be edged, punched, and cut with a ruler.
When it is suitable for external windows and external curtain walls, the design scheme should consider the combination of fireproof glass and PVB laminated glass. Scope of application: Fireproof doors and windows, fireproof partitions and important parts of fireproof partition walls in building rooms, corridors and passages.

Monolithic
Single-piece fire-resistant glass is a fire-resistant glass with a single-layer glass structure. Maintain the integrity of fire resistance for a certain period of time, block open flames and toxic and harmful gases on the fire surface, but do not have the effect of thermal insulation.
It is suitable for exterior curtain walls, exterior windows, skylights, smoke-blocking vertical walls, fire-resistant glass frameless doors, and partition walls without thermal insulation requirements.

perfusion type
It consists of two layers of original glass (or three layers of original glass for special needs), and is sealed with special flame-retardant adhesive strips around it. The fireproof glue poured in the middle is solidified into a transparent jelly and bonded to the glass.
Fire prevention principle: After encountering high temperature, the transparent jelly-like fireproof adhesive layer in the middle of the glass will harden quickly to form an opaque fireproof insulation board. While preventing the spread of the flame, it also prevents the conduction of high temperature to the back fire side. This kind of fireproof glass not only has fireproof and thermal insulation properties, but also has excellent sound insulation effect. Can be processed into arc.
It is suitable for fire doors and windows, building patios, atriums, shared spaces, and computer room fire partition partition walls.

According to fire resistance rating
According to the fire resistance rating, it is divided into 5 grades: 0.5h, 1.00h, 1.50h, 2.00h, 3.00h.

According to fire resistance
Heat-insulating fire-proof glass (Class A), non-heat-insulating fire-proof glass (Class C), and partial heat-insulating fire-proof glass (Class B).
