I recently helped an architect design a wood-framed wall assembly with different membrane arrangements on each side of the wall. We used the calculated fire resistance approach from IBC 722 to achieve a one-hour rating for the wall. This project led me to create a new tool that calculates the fire resistance of the wall assembly based on the materials that you choose for each side. Check it out at the link below!

Explaining Fire Resistance vs. Fire Protection Ratings for Opening Protectives

5/14/2021

6 Comments

 
In the A/E world, there is much confusion regarding the definition of fire protection rating and fire resistance rating when designing doors, windows, transoms, sidelights and other openings in rated construction. These terms are often used interchangeably by mistake, but they represent two very different types of assemblies. A third term, "fire rating", is often used as well, making the distinction even more confusing. In this article, we'll review the differences between fire resistance ratings and fire protection ratings and show you how to determine the requirements for your specific situation. All code references are to the 2018 IBC.
