Walls with a fire rating

If you have a firewall that's required, they offer, well, you have options, you could put masonry in there and take that through the roof and get yourself a one, two, three-hour rating, or they have insulated panels that are mineral fiber, and they're heavy. The four inches, one hour, the six inches, two hour, and the eight inch is a three-hour rating, and those panels could weigh eight pounds a square foot.

I mean, they're significantly heavy, and these panels are three and a half foot wide, and this could be 30 foot high, you know, and do the math, you know. You're talking like a heavy piece of equipment. You definitely have to have a vacuum rig and safety tethers on it.
