Alrighty! Got me some good 4" thick quadruple paned triple laminated blast resistant windows. I have to modify the inside of the tracking room wall, because the blast system uses a recoiling metal barrier structure between the windows that connects the frames together. This is a good idea of what I'm getting installed in about 2 weeks (that's not my building obviously).
It took me almost a month to figure out how to get in touch with a window contractor who could install them. I ended up going to some banks and police stations and asking who built their buildings. Once I got the name of the general contractors, I asked them who they used for windows. Once I got in touch with the window contractor, it was pretty smooth sailing from there.
Today I got a tour of the factory warehouse where they pre-assemble the window systems. I got to actually bang on some of the frames and see the anatomy of the glass construction up close. And man was it eye-opening. I also got to take a look at the way a bomb proof framing system is built underneath the wall. This glass can get smashed with a crowbar or sledgehammer and it won't budge. If entire wall takes a bomb, the glass breaks but it doesn't shatter.
What was downright amazing was when I stepped into the guys office. You couldn't hear a thing!! There were two gigantic air conditioners right outside the dudes window, and it was dead silent. He wasn't more than 80 feet off of one of the busiest roads in town, and absolutely nothing when you closed the door.
Here's a picture of the A room at Sweetwater in Fort Wayne Indiana. Like Blade (Echophone) studios in Louisiana (also designed by Russ Berger) the windows are injected with about 2-3 feet of depth. I don't have a big enough room to be able to take 2 feet off the wall. It'll cut the floor space back too far.
So the re-inforced cement blast system can achieve a relatively similar OTIC result without eating up all your floor space. I placed the order today. Should have it up and running in a few weeks! Yay.
