Fire Ratings for Wooden Doors

Wooden doors are a popular choice for both residential and commercial settings due to their natural beauty and warmth. However, when it comes to fire safety, it’s important to consider the door’s fire rating.

The fire rating of a wooden door is determined by its ability to withstand fire and prevent its spread. The rating is based on a series of tests that measure the door’s resistance to heat, flames, and smoke.

In the United States, fire-rated wooden doors are classified into four categories: 20-minute, 45-minute, 60-minute, and 90-minute fire ratings. These ratings indicate the amount of time the door can withstand fire and prevent its spread.

A 20-minute fire-rated wooden door can withstand fire for up to 20 minutes, while a 90-minute fire-rated door can withstand fire for up to 90 minutes. The fire rating of a wooden door is determined by the thickness of the door, the type of wood used, and any additional fire-resistant materials that are added to the door.

It’s important to note that not all wooden doors are fire-rated, and it’s crucial to check the fire rating of a door before installing it in a building. In addition, wooden doors that are used in certain settings, such as in stairwells or as part of an exit door, may be required to meet specific fire code regulations.

In conclusion, wooden doors can be fire-rated to provide increased fire safety in both residential and commercial settings. The fire rating is determined by the door’s ability to withstand fire and prevent its spread, and it’s important to check the fire rating of a door before installing it in a building.
