The most important thing here is to make sure the vendor has a UL rating on
the walls. As far as combining the walls, etc., this should also be in a
tested or certified configuration. UL has a book that shows the
configuration for a variety of walls, columns, beams, etc., and the fire
protection required for various times. It has been a long time since I have
tried to get a new one, so I don't know the vitals (phone no., website,
etc.), but I am sure you could find this on the net somewhere.

Subject: Firewall Construction
I am trying to understand the general requirements and details for firewall
construction. All the firewalls I have designed were masonry and were
restrained near the top of the wall.
Have any of you used insulated panels, (metal skin /foam insulation), for
firewalls? I have a spec sheet from a supplier that indicates that they can
get 3 hours on their panel.
This project involves a large freezer structure with a firewall down the
middle - (project is still preliminary - I'm not sure yet if this is really
a firewall or an area separation wall).
Assuming the panel indicated above will work, could we achieve a four hour
wall by using 2 panels with some separation between the panels, say 3", but
attach each panel to its separate structure?
Any thoughts will be appreciated!
