Fire Safety: Understanding EI45 Classification

The European fire resistance classification (EN 13501-2) evaluates two key factors:

E (Integrity) – The ability to prevent flames and gases from passing through.

I (Insulation) – The ability to prevent heat from transferring through the hatch.

A wall hatch classified as EI45 means it maintains both integrity and insulation for 45 minutes, providing crucial protection in case of fire.
