Understanding Fire Door Ironmongery
Fire door ironmongery, also known as fire door hardware, refers to the fire-rated hardware that allows a fire door to properly function during a fire. These include hinges, locks, handles, frames and seals that ensure a fire door not only closes but also keeps its fire-resistant properties intact. This helps prevent smoke and flames from spreading, keeping the area safe during a fire.Types of Fire Door Hardware
A fire door can only function at its best when it's equipped with the right ironmongery (door hardware). There are three essential components that every fire door needs: Hinges Quality fire door hinges are designed to support the door's weight and ensure smooth operation, even in extreme temperatures. They must meet specific fire safety standards and unlike regular door hinges, they must be made of materials resistant to heat. Frames, Linings and Casings The frame is key in securing the fire door and ensuring its fire rating. Fire-resistant linings and casings are essential for preventing the spread of heat and smoke around the edges of the door. Intumescent strips Intumescent strips and smoke seals expand when exposed to heat, sealing gaps between the door and frame to prevent smoke and flames from passing through. These are important to maintain the door's fire-resistance integrity. Handles Fire door handles must allow for easy operation, especially in emergencies. Handles should also be fire-rated and securely attached to avoid failure during a fire.Fire Door Ironmongery Regulations
Fire door hardware must be CE marked to uphold safety. They should also be tested to specific standards:- For locks and latches, the relevant standard is BS EN 12209.
- Hinges need to meet BS EN 1935.
- Door closers should be tested to BS EN 1154 or BS EN 1155.
