Transparent Fireproof Glass

Transparent fireproof glass does not just provide securement of clean field of vision, lighting, and openness during normal times. In case of a fire, it also allows effective handling during firefighting because preventing the fire from spreading and evacuating the room can be done conveniently when it can withstand flames from 30 minutes up to a maximum of 120 minutes.

Main Characteristics

While it was common to use wired sheet glass in the outside windows of a building or steel fire shutters in the fire prevention plan within the building in the past, in accordance with the relevant laws and regulations, it has become possible to finish with fireproof glass that is transparent like ordinary glass, without wire mesh or wire, as the demands of the consumers became more high-quality and diversified.

Type B

  • It is a transparent fireproof glass composed of a single sheet without a wire mesh inside the glass and during the heating test based on the KS standard, it achieved fireproof performance of 30 minutes without a thermal barrier.
  • According to the Type B fire door and fire prevention laws and regulations, it can be used in the outside windows, etc. of a building as a substitute for wired sheet glass.
  • Since it maintains transparency for a long time even in the event of a fire, it is possible to evacuate safely.
  • The impact resistance strength is excellent and even if it is damaged by an outside impact that exceeds the limit, it is safe since it breaks up into small particles.

Type A

  • Unlike existing fireproof glass, it is transparent without wire mesh inside the glass and it is produced by using a special float glass.
  • It has excellent fireproof performance that allowed it to withstand even the heating test that lasted for 1 hour at a maximum of 945℃ without shattering or melting.

Major Uses

  • Type A/Type B fire doors and non-combustible materials on the fire partitions
  • Smoke barriers
  • Indoor openings of emergency passageways in buildings
  • Interior partitions in offices and factories
  • Fire prevention partitions in product warehouses
  • Windows at places that handle fire hazard materials
  • Other storage locations for computers and critical data
  • Places where human access is frequent and safety and fire prevention are required like public facilities, hospitals, etc.

Fireproof Glass Types Fireproof Glass can be largely divided into Fireproof Glass without a thermal barrier and Fireproof Glass with a thermal barrier.

Fireproof Glass without a Thermal Barrierclass E

  • Form Mainly composed of a single sheet
  • Purpose To prevent the spread of flames for some period of time
  • Performance Criteria During a fireproof test, there must be no flame occurrence or flame penetration on the collapsed or heated surface of the test specimen

Fireproof Glass with a Thermal Barrierclass EI

  • Form A form obtained by inserting a resin layer between two or more sheets of glass and laminating them
  • Purpose It is very effective during safe evacuation and firefighting because it blocks heat transfer due to radiation and conduction in addition to preventing flames from spreading in case of a fire.
  • Performance Criteria In addition to the fireproof performance required by the fireproof glass without a thermal barrier, there must not be any temperature increase above a certain standard on the non-heated surface.
