In my experience, you don’t save very much buying used, because most of the cost is labor. Also, where the panels fit together, they need to be fitted exactly the same – you can’t mix and match panels when the construction is a sandwich of metal sheets with something nonmetallic within. That material within takes a set, and if you don’t put it together the same way it came apart, the room will leak. So if a room is already torn down, and the panels aren’t marked so that the original constriction can be perfectly recrerated, I wouldn’t buy. If the room you are to buy is still up and needs dsiassembly, then it has to be done as I described. There are outfits that do this. I used to know one in CO, but don’t know if it I still around.
There ae other constructions where the panel is simply a thick sheet of metal. These likely aren’t as critical to reconstruct identically to original. -- Ken Javor Ph: (256) 650-5261 From: Ralph McDiarmid <[email protected]> Reply-To: ***** IEEE emc-pstc List ***** <[email protected]> Date: Friday, August 8, 2025 at 1:34 PM To: <[email protected]> Subject: Re: [PSES] Design a chamber from scratch- what are your top 5 features? Patrick, the first item on my list would be how much budget to I have? Have you considered buy (2nd hand) versus DIY from scratch?. There are a few, used semi-anechoic chambers out there somewhere. You might discover that buying is cost-effective in terms of money and time.

I have the opportunity to design an EMI chamber from scratch. I'm generating a list of all my loved features, and hated features. Here are a couple that come to mind. Loved: abundance of overhead lighting Hated: lighting only with flood lights in upper corners Loved: replaceable bulkhead passthrough panel Hated: all of the bulkhead panels at ankle height If you were building, what is your love/hate feature list? (spoiler alert- I will copy your ideas into my design!) Many thanks ! Patrick. This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
