Fire-Resistant Glass for Vision Panels in Fire Doors

A fire-resistant glass vision panel is a small glazed section within a fire-rated door, designed to allow visibility while maintaining fire integrity and insulation. These panels are essential in commercial buildings, hospitals, offices, and schools, where safety and monitoring are crucial.

1. Fire Rating Requirements for Vision Panels

Fire-rated vision panels must match the fire resistance of the door, typically:

Fire Door Rating	Required Vision Panel Rating	Duration
FD30 (30 mins)	EI30 / E30 Glass	30 min
FD60 (60 mins)	EI60 / E60 Glass	60 min
FD90 (90 mins)	EI90 / E90 Glass	90 min
FD120 (120 mins)	EI120 / E120 Glass	120 min

2. Types of Fire-Resistant Glass for Vision Panels

E-Rated Glass (Integrity Only)

• Prevents the passage of flames and smoke.

• Does not stop heat transfer.

• Suitable for compartmentalization but not insulation.

EW-Rated Glass (Integrity + Radiation Control)

• Reduces heat radiation to limit fire spread.

• Commonly used in fire doors and internal partitions.

EI-Rated Glass (Integrity + Full Insulation)

• Prevents both flames and heat transfer.

• Used in high-risk fire zones like escape routes.
