20 Minute Fire Doors
Why is a 20 minute fire door needed?
In residential construction, a 20 minute fire door is commonly used for the entry from the garage to the house. Building codes vary across the U.S., so please be sure to check local standards before purchasing.
Do I need both a fire rated door and fire rated frame?
Yes, both the door and frame are required to meet fire-rating standards. A compatible fire-rated frame is essential, as there are specific installation requirements to ensure the door functions effectively in the event of a fire.
