Congratulations David. You know the drill to get your books.

R. 303.3 on the insulation David.

Which answer did you accept, he wrote two.

F is the answer. Maybe…
R602.8.1 Materials. Except as provided in Section R602.8, Item 4, fireblocking shall consist of 2-inch nominal lumber, or two thicknesses of 1-inch nominal lumber with broken lap joints, or one thickness of 23/32-inch wood structural panels with joints backed by 23/32-inch wood structural panels or one thickness of 3/4-inch particleboard with joints backed by 3/4-inch particleboard, 1/2-inch gypsum board, or 1/4-inch cement-based millboard.
Batts or blankets of mineral wool or glass fiber or other approved materials installed in such a manner as to be securely retained in place shall be permitted as an acceptable fire block. Batts or blankets of mineral or glass fiber or other approved non-rigid materials shall be permitted for compliance with the 10 foot horizontal fireblocking in walls constructed using parallel rows of studs or staggered studs.
Loose-fill insulation material shall not be used as a fire block unless specifically tested in the form and manner intended for use to demonstrate its ability to remain in place and to retard the spread of fire and hot gases.

My point exactly…So technically my answer is correct. If a material did demonstrate those properties it could be used, Its in the wording.

His first answer of False. The T is referring to his article that he provided a link for.

I made an error on the reference where it should of been R 302.11.1.3
where it states that Loose-fill insulation material shall not be used as a fire block.

You’re the boss so I will respect your decision. But I believe the last part of the code you sited leaves the possibility open to use Loose-fill insulation.
unless specifically tested in the form and manner intended for use to demonstrate its ability to remain in place and to retard the spread of fire and hot gases.

Where did this R 302.11.1.3 come from.
Mine was from the ICC?
I’m not disputing you, I just want to know?

2009 IRC

Yes, can be used when specifically tested for that application.
How often do you think that would happen in the residential arena? Pretty slim. :slight_smile:

Not likely, but I am sticking to the answer being True because of the wording of the code.

Good questions Marcel, keeps everyone on their toes! :wink:

Thanks for the questions Marcel, learned something again.

Give him hell Kris!
Either it is an absolute or it ain’t.:D:cool:

Exactly! All over these threads inspectors are being told to pay attention to how things are worded.
