Guide on installation practices of a fire-rated interior door

Introduction:

Interior fire-rated doors play a most important part in the fire protection sequence, slowing down the flames and smoke that enhance the chances of occupants getting away or escaping fire hazards. As per design, interiors are intended to last for some time wherein they would hold up against fire exposure for the purposes of controlling the affected area by fire. 

An installation is efficient, whereas poorly installed or neglected ones will fail when they are most needed for their ultimate purpose. This guide is an overview of steps through which the honorable introduction into installing fire-rated interior doors, including framing and hardware installation, will also include good practices that will enable these systems to work efficiently for ages. 

Step by Step Installation Guide for Fire-Rated Interior Doors

1. Check for Certifying Labels on Door and Frame: 

Confirm the presence of legitimate fire-rating labels on both door and frame at the time of installation. In addition to confirming both items are appropriate and equal, all must comply with the required requirements according to fire safety standards.

2. Preparation of the Doorway Opening

• The doorway opening must be calculated so precisely that the door fits snugly. 
• There must remain sufficient space in between the frame-wall boundaries to allow for adjustment and positioning. 
• The wall structure has to be sturdy enough to support the door and its normal operations.

3. Frame the Door 

• Fix the opening adequately level to mount the frame straight then vertically. 
• Use fine tuning with shims which should in turn be secured with either fire rated screws or anchors. 
• Ensure no such thing surrounding the door frame has to frictionless movement and leakage may occur by either size of small holes while going through both smoke and fire.

4. Attaching door frame 

• Fire rated hinge is used to attach the door installed in the frame to the approved screw fastening that makes a rigid connection. 
• The hanging of the door should allow it to swing freely, being checked for proper open or close without catching the edges against the door frame. 
• To withstand the containment of the fire, it must remain self-closing and latch shut. 

5. Sealing and Fire Protection 

• The edges of the door are installed with intumescent seals. These seals will expand with high temperatures to ensure that fire and smoke will not spread.
• Install smoke gaskets encircling the door frame such that toxic smoke cannot go to other areas.

6. Installing Fire Rated Hardware

• All fire rated locks, latches and closers to maintain fire resistive integrity of the door.  
• Install all components per directions by the manufacturer for correct functioning.
• Fire resistant nameplates and markings should not constitute more than 5% of the total area of the door. 

Best Practices in Fire Rated Door Maintenance. 

So as to keep your fire-rated interior doors pristine and within safe functional limits, adhere to the following general maintenance rules.

1. Regular Inspection

• Inspection of fire doors: Fire doors should be inspected at least on a biannual basis during that month of the year to ascertain their continued optimum function. Key areas to check include.
• The Door Surface-the surface may have cracks, dents, or warping that may compromise the fire resistance of the door.
• The seals and gaskets-all protective seals and gaskets must be in an intact condition and should not show any sign of wear or damage. 
• Hinges and Latches-all hardware should be confirmed as being attached-damage-free and operating with full efficiency.

2. Lubricate Hinges and Moving Parts

• Dirt and dust must be removed from hinges and with moving parts.
• Add a silicone-type lubricant which is not based on oil to keep the door running smoothly as dust would not collect on it. 

3. Keep the Door in Its Original Condition 

• Unauthorized Alterations: Do not make unauthorized alterations, as this would void its fire rating. Holes drilled into it, for example, with additional locks, or cutting into the door, constitute tampering with the door. 
• Close properly. Fire doors should always close completely and latch automatically-never prop them open. Replace any parts of the door, frame, and hardware that are damaged. Repair or replace them with fire-rated materials. Common Mistakes Not to Be Made in Fire-Rated Doors.
• Using Non Fire Rated Hardware-All locks, hinges, and latches should be fire-rated so that the fire protection capabilities of the door remain intact.
• Misalignments and Settings of Doors-Doors should not have large, unprotected gaps because this also cuts down on the fire resistance. Because fire doors do need to be held in use as an effective barrier against fire, lack of adequate inspection and/or maintenance may lead to a gradual decline in their effectiveness.
• Keeping Doors Open-If the door doesn’t contain an automatic closing device, it is considered useless-as a fire door when left open isn’t of any use in preventing the spread of fire when needed.
