When the window area exceeds the maximum exposed area specified for fire-rated glass, it is

necessary to split the window into sections that comply with the fire rating requirements. This means

creating smaller sections that are each within the 3 sqm/32 sqft limit and using fire-rated frames to

ensure that the entire assembly meets fire safety standards. This approach maintains the fire-rated

integrity of the glass, while allowing for larger window areas.

Detailed Explanation:

Fire-rated glass is designed to contain fire and prevent it from spreading. If the window exceeds the

maximum exposed area defined by the supplier, the integrity of the fire-rated glass could be

compromised. By dividing the window into compliant sections with fire-rated frames, you ensure

that each pane performs as intended in the event of a fire. Fire-rated frames help maintain the fire

resistance across the entire assembly, making this option the best for safety and compliance.

EPI Data Center Specialist Reference:

EPI recommends adhering strictly to fire safety standards, especially when using materials like fire-

rated glass. The guidelines emphasize that modifications should always respect the manufacturer’s

specifications to ensure the system remains effective in containing and preventing the spread of fire.
