How to meet the 2 hour separation between an A2 and R2

[jar546]

First floor is an A2 in the front with R2 in the back.

Second floor is all R2 directly above the A2.

So how do you meet a 2 hour fire separation for the new A2 going in the existing unsprinklered building?

Paint!

There are some out there. Need special inspections.

Some of these products can also be used to raise construction type, Otherwise unprotected steel, Type IIB construction, could be elevated to IIA or even Type I depending on the applied thickness and final fire resistance rating achieved.

Not sure about overall cost benefit though. Material cost may (or may not) be comparable, but the special inspectors and inspections may increase costs for the project.

Coin toss?

Lots of paperwork and special inspections for sure. Mfg required special inspections too.

They have lots of testing data to support up to 2 hours but it is dependent on the type of existing construction which they must evaluate first. The mfg already stated that they can't help everyone.

UL won't apply but they have worked a lot with FM

How do you use paint to provide a separate fire area for the new A-2. Two A-2s would be 100+ occupants, I assume that the R-2s have an excess of 1 occupant? Non sprinkler building.
