Panelled fire doors are independently tested and then given a rating that shows the minimum amount of time they are guaranteed to stop the spread of smoke and fire for. By stopping smoke and fire spreading in your home, you and your loved ones can safely evacuate and call for help.
Door rates are given numbers, which shows the minutes they’re guaranteed to block fire and smoke for. The most common rating for domestic use is FD30 which means it will stop fire and smoke for a minimum of thirty minutes. Some other common ratings are FD60 and FD90 which are more common in commercial buildings.
