How to build a half hour fire separation wall? Is it ok to use regular half inch drywall on both sides of the 2 x 4 framing? Would insulation be needed if it is just for a half hour interior fire separation wall?
Every municipality has their own code you have to follow so you can give your city hall a ring and they will tell you the requirements.
In Niagara that's what we did though, it may have changed since the last time I did that was a year and a half ago. It always changes.
I recommend you give City Hall a call as well to be 100% correct depending on your municipality. However I strongly recommend you use 5/8 fire-rated drywall and install it right over top the existing drywall or plaster that is there. This would definitely give you half an hour of fire rated
I'm having to edit my reply. My original post was based on memory and now I have looked up the answer. It seems that 1/2" regular drywall with insulation will get you a half hour rating. Not sure if lightweight drywall would qualify - needs to meet ASTM C 36/C 38M Gypsum Wallboard or ASTM C 1396/C 1399M Gypsum Board
