How does Integrity & Radiation Control Glass differ from regular glass?
Regular glass shatters under heat, while Class EW Glass is designed to withstand fire and minimise radiant heat transfer, reducing the risk of secondary ignition.
What is the testing standard for EW rated glass?
It is tested under EN 1364-1 (for partitions) and EN 1634-1 (for doors and windows) and classified as per EN 13501-2.
How is fire rated glass of classification EW tested for radiation control?
It undergoes fire exposure as per testing standards, to ensure radiant heat flux remains below 15 kW/m² at 1m distance, limiting radiation.
Can EW fire rated glass be customised for specific applications?
Yes, it can be produced as laminated or insulated glazed units, with design and performance customisations.
How does EW glass meet the requirements of international radiation standards?
It complies with EN 13501-2, ensuring fire integrity and radiation control under standard conditions.
What is the maximum size for integrity & radiation control glass of class EW?
Sizes vary based on the fire rating and specific project requirements. Large format options are available upon request.
Can EW fire rated glass be used in outdoor applications?
Yes, it is suitable for exterior use when produced as insulated glazed units, with a high performance coating.
Related Classification
EI classification
Class EI (Insulation) fire-rated glass is the highest performance classification and blocks the transfer of heat while stopping flames, smoke, hot and toxic gases.
E classification
Class E (or Integrity only) fire-rated glass provides a barrier against the passage of flames, smoke, and hot, toxic gases.
