The Specialty of Glazing Used in Fire-resistant Doors

Building design and construction experts are responsible for creating safe, code compliant working and living spaces that can save life and property during a fire.

Although the focus is always of fire-resistant doors, often we forget about the importance of glazing that forms an integral part of many doors.

Visibility is a very important factor in ensuring safety during a fire and is the reason why it makes sense to have glazed fire-resistant doors like the ones offered by a Sacramento door company instead of all steel doors.

The Specialty of Glazing Used in Fire Resistant Doors

However, fire resistant glazing is no ordinary glazing and must comply with the codes of safety that are constantly evolving. Therefore, choosing the right specification of glazing can be challenging due to the confusion that arises from time to time about proper adherence to the codes.

By ensuring that the glazing meets the latest codes you are sure that it fits the stringent fire and life safety code that can save life and property in the event of a fire. The salient features of fire-resistant glazing will become clear on going through this article.

How Much Defense Does the Product Offer?

To make the process of selecting the right specification of glazing easy, it is better to look at it very objectively and focus on its ability to provide protection against fire. Considering what kind of defense, the glazing can provide will help to evaluate how much useful it will be and how well it matches with your expectations.

Fire rated glazing comes in two varieties – fire protective glazing and fire resistive glazing. Understanding the differences between the two should help to choose the appropriate product with compromising on safety.

Fire Protective and Fire Resistive Glazing

• Fire Protective Glazing – Fire protective glazing design is unique because it helps to compartmentalize buildings by preventing spreading of fire and smoke in accordance with the designated fire rating. This glazing is suitable in places where the building codes allow the creation of an enclosed space earmarked as ‘opening protective.’

• Fire Resistive Glazing – Fire resistive glazing goes a step ahead and adds another layer of protection by blocking the transfer of conductive and radiant heat. It is tested against the stringent fire resistance parameters that are set as standards for walls including UL 263 and ASTM E119 and can, therefore, exceed the total wall area by 25%.

Adherence to the codes displays the fire resistant or protective quality of glazing.

Conformity to the Fire Rating

Code standards are not uniform across the building but vary by location and occupancy in the building. Glass and frames have different fire ratings between 20 minutes and 180 minutes or 3 hours that you can find in the product label. The number on the label confirms that the material has been tested in accordance with the designated fire standards.

Lastly, to be sure that there is no mistake in the selection, have a look at the test certificate to ensure that the glazing has passed all tests like impact resistance, bullet resistance, hurricane resistance, etc besides fire test provided the application demands it.
