Nothing says you can’t install fire doors at your home. However, before doing that, here are some things to check:
Check that a fire door fits into the current frame: FD60/120 fire doors are typically 45mm thick compared to a standard 35mm door thickness. All newly installed fire doors must be installed by a professional, as in the event of a fire they might not function properly without proper installation. Without following these recommendations, there is no guarantee that your fire rating will be correct.
FD60 provides 60 minutes and FD120 provides 120 minutes of fire protection and is suitable for all domestic as well institutional situations.
If you are replacing the interior door and your home does not currently have fire doors, fire doors are not necessary (but they can improve the security of your home).
It depends on the type of your property. Please refer latest NBC(National Building Code) or contact Navair representative.
In cases where there are fire doors in offices/Public Buildings/apartments, user/owner may want to lock the doors to their office/rooms/services area etc. All exit fire doors are being used with Panic bar from inside (push side) / and Panic trim with lock (optional) from outside (pull side). People can use panic bar during emergency even if it is locked from outside.
It would actually depend on the extent of the damage to the door, but it can only be assessed by a certified person. If the damage to the door itself is visible, we recommend that you invest in a new fire door for safety reasons.
Use this short 5-step process to verify that fire doors are certified and tactile:-
● Check the top or side of the door for a certification label. Here it must be specified about the testing standard and fire rating of the door.
● Use a 1 rupee coin to check the gaps on the top and sides of the door. There should be a gap of 4mm. So if you are testing with a 1 rupee coin, there should be 1mm of clearance left. If there are more, the door may not work as expected.
● Are the seals around the door or door frame intact? If they hang or appear loose, the door may be damaged.
● Are the hinges tight? If they are loose or wobbly, the door has not been repaired.
● Open the door and let it close on its own. Does it close properly? If so, it is in good condition.
