2 Hour FIRE RATED WINDOWS

The Protection of 2 Hour Fire Rated Windows

In commercial and multi-unit residential buildings, the use of appropriate fire-rated materials is paramount to ensuring the well-being of occupants and protecting property. One critical component is the use of fire-rated windows, specifically those listed and labeled to withstand fires for extended durations, such as one-hour (60-minute), 90-minute, or even two-hour (120-minute) windows. Let’s explore the features, applications, and advantages of fire-rated windows.

Understanding Fire-Rated Windows

Fire-rated windows are designed to resist the spread of flames and smoke during a fire for specified durations. Designations such as 45-minute, one-hour/60-minute, 90-minute, or two-hour/120-minute refer to the window’s ability to maintain its integrity and insulation against fire, heat, and smoke in the event of a fire for the specified timeframes. These classifications are crucial for providing occupants with sufficient evacuation time and enabling more effective responses from firefighters.

Features of Two-Hour Fire-Rated Windows to meet UL 263 or ASTM E119

Extended-duration fire-rated windows, such as two-hour (or 120-minute) fire-rated windows, offer the maximum levels of resilience and protection. Crafted with fire-resistive glazing materials, including tempered glass and advanced elements, these windows act as a shield against high temperatures and prevent structural failure amidst prolonged fire exposure. These windows’ integrity and insulation form a linchpin for slowing the progression of fire and establishing a secure zone for evacuation. In addition to rugged fire-rated glass, specialized seals and gaskets play a role in the two-hour fire rating of these windows, effectively sealing the window against flames and smoke.

Containing a fire within specific compartments not only protects occupants and allows time for safe evacuation but mitigates a fire’s impact on the overall structure. To be sold as such, two-hour fire-rated windows must undergo rigorous testing by recognized laboratories. Such labeling provides assurance not only to the specifying architects and contractors but to the end users of the structure as well.

Applications for Two-Hour Fire-Rated Windows

Extended-duration fire-rated windows are called for across the construction landscape. Mandated in many commercial structures and high-rise buildings where the risk of fire escalation is heightened, these windows become integral to ensuring compliance with building codes, safeguarding the occupants, and protecting valuable assets.

In facilities housing critical infrastructure like data centers, server rooms, and control rooms, the use of extended-duration fire-rated windows is paramount. Two-hour/120-minute fire-rated windows help to create fire-resistant compartments that provide a protective shield for critical equipment essential to the facility's operations. Furthermore, in healthcare facilities, including hospitals and skilled care facilities, extended-duration fire-rated windows are crucial. Their use is vital to ensuring the safety of patients, especially those with mobility challenges, during a fire emergency. Finally, two-hour fire-rated windows are essential for zero lot line windows and an appropriate choice for high-rise buildings, where extended evacuation is often necessary.
