The Difference between FD30S and FD30 Fire Doors
There are different fire ratings for fire doors and these doors provide different levels of protection depending on the needs of the building and the people using it.
“We offer standard fire doors at Doors Direct 2 U with FD30 ratings.”
There are a variety of fire doors that lead to escape routes, but the most common is FD30. FD30 doors can withstand fire for up to 30 minutes.
Due to their smoke brushes and intumescent strips, FD30S Fire Doors resist fire as well as cold smoke. According to the National Fire Protection Association, smoke inhalation causes 42% of fire-related deaths, which means these strips on doors can make the difference between life and death for some people.
A fire door that meets the FD30 fire rating is fire resistant for 30 minutes, while a fire door that meets the FD30S fire rating is fire AND smoke resistant for 30 minutes. Additionally, the door is smoke resistant, as evidenced by the S rating.
FD30s: What Are Their Roles in Fire Safety?
To prevent fire from spreading, buildings are compartmentalized.
To facilitate the flow of traffic around the building, these compartments are usually connected by fire doors.
A fire door performs two critical functions. They:
1. Create a fire barrier when closed
2. Create an escape route when opened
When properly manufactured and installed, FD30s will retard the spread of fire and smoke in a building or workplace without hindering people and goods movement.
All FD30s are tested to determine their ability to act as a barrier against varying degrees of smoke and/or fire based on where they are located within the building and the fire hazards present within it.
ARE INTUMESCENT STRIPS REQUIRED FOR FIRE DOORS?
Where there are fire doors, intumescent strips are required, according to the Building Regulations. It is estimated that a door without intumescent strips would not prevent fire from spreading for half as long, putting the occupants or residents of the building at greater risk of death or injury.
In order to prevent fires and smoke from spreading, fire doors are essential. Door fire resistance is specified by its FD120 FD90, FD60, and FD30 numbers, each of which represents how many minutes the door can contain a fire. FD90S, FD60S, FD30S, and FD120S are fire doors that also require smoke protection.
In order for the door leaf to be free to move within the frame of a standard fire door, there has to be a small gap around the perimeter. If however, the gap is too large, the door may not be able to prevent fire and smoke from spreading.
Strips, locks, and smoke seals, which are intumescent materials, play an important role in preventing the spread of fire and smoke. Most importantly, they reduce the risk of death and injury, as well as property damage.
The door itself contains intumescent strips. Activated by heat, the materials swell and form a seal. A fire door creates a secure seal between the door and the door frame which fills the space between the door and the frame. The fire is prevented from spreading, and the room or compartment is contained.
Fire doors also feature intumescent strips, which prevent fire from spreading through a window.
