What Is Fire-Resistant Glazing?

Fire-resistant glazing consists of specialised glass types engineered to resist fire and smoke penetration for a specified period.

Unlike standard glass, fire-rated glass is treated to withstand extreme heat and prevent shattering, warping, or heat transfer that could accelerate fire spread.

Types of Fire-Resistant Glass:

  • Integrity-Only Glass (E-Rated) – Prevents the passage of flames and smoke but does not block heat transfer.
  • Integrity & Insulation Glass (EI-Rated) – Provides thermal insulation, limiting heat transfer and reducing the risk of ignition on the non-fire side.
  • Integrity & Radiation Control Glass (EW-Rated) – Limits heat radiation, offering partial thermal protection.

Each glass type is rigorously tested to ensure compliance with fire resistance classifications of 30, 60, 90, or 120 minutes.

Why Fire-Resistant Glazing is Essential

Compliance with UK Fire Safety Regulations

Fire-resistant glazing is a legal requirement in certain areas of buildings, including escape routes, fire doors, partitions, and stairwells. Regulations such as BS EN 13501-2 and Approved Document B mandate its installation to enhance fire compartmentation and occupant safety.

Containing Fire and Smoke Spread

In the event of a fire, fire-rated glass acts as a barrier against flames and smoke, preventing rapid spread and ensuring escape routes remain clear and protected.
