Internal doors to integral garages should be FD30 fire doors , and include smoke seals and self - closing devices. These are the only doors inside a dwelling that require self - closing doors. Self -close hinges are a type of hinge that has a spring built into it so when you start to close a cabinet door, the spring, at some point, takes over and pulls the cabinet door closed with a tap. Just stick a few small felt pads along the edge of the doorframe: Position a pad at the top and bottom of the frame, along with two more pads at the top and bottom of the strike plate.
The pads provide just enough soft cushioning to slow down the door as it closes, preventing a slam. Shush with weather stripping. Grab one or two felt pads and stick them inside the door frame. You can put them around the lock area, or spread them out closer to the top and bottom. The pads will catch the door before it hits the frame. While it won't completely silence the slam , it will quiet it, providing you some protection from the sound. Remember, when it comes to turning door closer adjustment screws, a little goes a long way.
Turn the adjustment screw clockwise to slow the door closer down, counter-clockwise to speed it up, then get down off the ladder and observe the effect. Open the door and watch it close. A spring - loaded hinge should only be removed when the door is closed to avoid it slamming. Using a hex wrench, open the spring so you can see the tension pin. Then, remove the pin using pliers. You can then remove the hex wrench and allow the spring to naturally unwind.
Turn the "L" screw clockwise to increase the speed with which the door closes during the last one-third of its swing. Alternatively, turn it counterclockwise to reduce this speed. Increase the pressure it takes to open the door by turning the "BC" screw clockwise. Turn it counterclockwise to reduce this pressure. Use screw 1 to adjust the doors from side to side. The standard specifies the type of fasteners that must be used — steel machine screws to secure mortise hinges to reinforcements in a door, and steel wood screws No.
Steel through-bolts are required for surface-mounted hinges. For attachment to the frame, hinges must be secured with steel screws, but the type of screw will vary depending on the frame material. Hinges on fire doors may be shimmed, but steel shims must be used. Shims of cardboard, wood, plastic, or other materials do not meet the requirements of NFPA In some cases, hinges must be shimmed during or after installation to properly align the door in the frame and bring clearances into compliance with NFPA Shimming is allowed, but steel shims must be used.
The hanging components — hinges, pivots, and continuous hinges — are just one part of a fire door assembly, but they play an important role. If the hinges are specified, supplied, or installed incorrectly, the door will not swing freely. Incorrect fasteners may cause the door to sag or even come loose from the frame.
Clearances can be affected by this misalignment, and the door may not close and latch properly, impacting the ability of the assembly to deter the spread of smoke and flames during a fire. Lori, I vaguely remember that there was a time, perhaps fifteen to twenty years ago when NFPA 80 dictated a bearing rather than spring hinge in the upper location.
Do you have any info on this? It could have been in an older edition but it seems like an odd thing to remove. Your input is appreciated. Hi, Lori, we produce UL-Grade1 fire-rated self-closing hinge.
And we hope to consult some fire door issue with you. We have Aluminium series self-closing hinge. I want to know is any fire code can use this type of hinges. Also, I want to hire somebody like you who know SEO and have the door domain knowledge like you to help us write the introduction article. Can you do this or introduce someone to help me? Lori, Are weld on hinges allowed on hollow metal fire rated doors with internal metal stiffeners as long as the door is fire rated?
This is not specifically addressed by NFPA 80 so it would be up to the listings of the hinge, door, and frame manufacturers. So in researching some of the more uncommon things I run into during Inspections, I saw this article in your archives. In my research I found in the table 6. Am I missing something here. It looks like that line of the table in NFPA 80 applies to spring hinges. Let me know if you disagree. A door with a […]. If you're using one spring hinge per door, install it in the middle hinge position, with standard hinges at the top and bottom.
For doors with two spring hinges, use a standard hinge at the top with spring hinges in the middle and bottom positions. Use the screws that come with each hinge to secure the hinge in place. Ask a friend to hold your door in place while you screw it to the frame.
Use the screws that came with your hinges to secure the door to the frame. Close the door and adjust the tension. If your spring hinges feature a hex opening on top of the barrel, insert an Allen wrench and turn it clockwise to increase tension.
Insert a locking pin, which comes with the spring hinges, into the first hole that is revealed when you turn the Allen wrench. Remove the Allen wrench and test the door. If it closes and latches automatically, your project is complete. If not, reinsert the Allen wrench and move the locking pin to the second hole.
