I have a condo unit that previous owner ripped out a section of kitchen wall that is adjacent to hallway. Existing wall is one inch thick, 1/2" sheetrock over 1/2" brown fire resistant board(no idea what that is)
The contractor suggested 2 layer 5/8" sheetrock to meet the code.. That means I have to add 1/2" to existing area and the new wall will be thicker than the steel door frame..
Is it possible to use 1" thick material that meets fire code ? Thanks! --96.253.xx.xx |

Could go to company that makes fire doors then have fabricate a metal assembly made of steel along with steel panels then install. Another option if have a flux core welder is to fabricate metal wall assembly make out 1” tubular steel then install Roxul insulation then weld in metal sheet metal then install some porcelain tiles over where that will be proof. Metal will not burn. With the company that makes fire doors will have a fire rated label. --216.110.xxx.xxx |

I asked the town inspector directly, 2 layers 5/8" drywall, 1 hour rating.. I guess my math was off.. and nothing else satisfy that.. lol..
WMH, long time no see.. I am entering semi-retired life style. Then my friend wants to be independent contractor, so I am doing rehab/flip so that he has something to keep him busy.. --96.253.xx.xx |

A simple call to your local building inspector office for the local code.
Also ask about the brown fire resistant board.
AND don't forget the red spray foam to seal each hole or crack. (holes for wires, plumbing, etc)

DH had to rebuild a fire rated wall between the two townhouses that previous deadbeat owner ripped out the firewall to make it a SFH and fought the town on their "househacking moratorium." --64.246.xxx.xx |

2 layers of 1/2" Type C drywall board on both sides of the studs will give you a 2 hour fire rating for that wall assembly. --107.141.xx.xxx |

Scott, the other side is hallway of the condo, I don't know how it is constructed. the studs are 2x6" wood frame..
about 1/3 of the wall needs to be put back.. I was thinking of doing 2 layers of 5/8", then feather into existing area.(not perfect smooth)
When I asked the inspector, any material I can use to flush with existing wall, he was quick to say, 5/8 5/8.....
This is new to me and the contractor I use also mentioned 5/8.. If Type C meets the requirement, that would be great. Thanks for the comment. --96.253.xx.xx |

Elliot, 2 layers of 1/2" Type C will provide better fire protection than 2 layers of 5/8" regular drywall board. Maybe the inspector and contractor were suggesting 5/8" Type C or maybe Type X?? --107.141.xx.xxx |

The two hours fire separation was required when there was a change in use code type or a different user. So depending on how those two factors play out with impact how code enforcement will look at it.
Here is an example:
I had a day care center that rented four spaces from me - that was only one user. The office and two other spaces needed only one hour separation as they were classified for business. The space where infants and children under age four were in were classified as institutional use, and the space between that and the other spaces had to two hours. Additionally there had to be two hour separation between those four spaces and the union hall next door and the dance studio on the other side.
Of note - those two sheets have to installed different directions - one upright and the other on its side - so seams did't line up.
