Overview
The Blockcurtain EI 60/EI 120 is a certified fire-rated textile curtain system designed to compartmentalise buildings during a fire, preventing the spread of flames and heat across large openings. The curtain remains concealed within a compact galvanised steel headbox during normal building operation and descends automatically on fire alarm activation, resetting when the alarm clears.
What Does EI60 / EI120 Mean?
The EI fire rating defines a building element’s ability to resist fire under standardised test conditions:
- E – Integrity: prevents flames and hot gases from passing through to the non-fire side
- I – Insulation: limits heat transfer so the unexposed face does not exceed 140°C average
An EI60 curtain maintains both properties for 60 minutes; EI120 for 120 minutes. Both are tested to EN 1634-1 and classified to EN 13501-2.
