EI30 Fire-Rated Glass: Essential Guide

EI30 fire-rated glass is a fire-resistant glazing solution that provides 30 minutes of protection against fire, smoke, and heat transfer. It is commonly used in commercial buildings, hospitals, schools, and offices where short-duration fire resistance is required.

The EI30 classification follows EN 13501-2, meaning the glass meets these fire safety criteria:

Symbol	Meaning	Protection Provided
E (Integrity)	Prevents flames and smoke passage	Stops the spread of fire
I (Insulation)	Blocks heat transfer	Maintains surface temperature below 140°C
30 (Minutes)	Duration of fire resistance	Provides 30 minutes of protection

Types of EI30 Fire-Rated Glass

EI30 glass is designed with multiple layers, usually containing an intumescent interlayer that expands in heat to provide insulation. Common types include:

Laminated Fire-Resistant Glass

• Consists of two or more layers of toughened glass with fire-resistant intumescent interlayers.

• Provides full insulation and blocks heat radiation effectively.

Gel-Filled Fire Glass

• Contains a gel-based interlayer that absorbs heat and turns opaque during fire exposure.

• Offers high thermal insulation and improved visibility in normal conditions.

Applications of EI30 Fire-Rated Glass

EI30-rated glass is commonly used in areas that require short-duration fire resistance, such as:

• Fire-Rated Doors & Partitions (office buildings, hospitals, commercial spaces)

• Glazed Internal Walls & Partitions (separating fire compartments)

• Exit Routes & Escape Pathways (corridors, lobbies, stairwells)

• Smoke & Fire Barriers (between fire-rated sections in buildings)

Compliance & Certification

EI30 fire-rated glass must comply with global fire safety regulations, including:

• EN 13501-2 (European Standard)

• BS 476 Part 22 (British Standard)

• UL 10C / NFPA 80 (American Fire Door Standard)

• ASTM E119 (US Fire Endurance Test)
