If you have typical gypsum on the wood frame wall, it won’t resist damage from fires very long. However, if you use the right techniques and materials to construct your wall you can extend the length of time that your wall can resist fire and achieve an hourly fire-resistance rating. If the wall stays intact, then you can prevent the fire from spreading while waiting for the firefighters to arrive and put it out. Using a UL listed #fireresistantboard is an effective method of increasing the wall’s fire resistance. https://bit.ly/31ow06O
