Pyroguard · evidence reference CF437 (Warringtonfire Certifire, stated validity to 19 Feb 2031)
Within stated validity to 19 Feb 2031; issuer status still requires checking
This glass can achieve different fire ratings depending on how it is used — internal or external, door or screen, single or double-glazed unit, and the framing system. Each record below must be checked against the current certificate, test regime and complete framing, seals, fixings, installation and exposure. Only explicitly reviewed mappings carry review provenance; other extracted data remains unverified.

Understanding the grades
Integrity for the classified duration. It does not establish radiation control or insulation.
The complete system and classification report determine E performance.
Integrity plus a radiation limit for the classified duration. EW is distinct from E and from EI.
Check radiation performance in the system classification report.
Integrity plus insulation for the classified duration. A BS 476 integrity/insulation pair alone is not an EN 13501 EI classification.
Specify class and minutes from the project fire strategy.
Manufacturer location/exposure terminology, separate from fire-resistance class. Confirm the specific glass, system and installation conditions.
Internal/external suitability cannot be inferred from the letters E, EW or EI.
