Awesome build!
Curious on the sheet metal bits, where edges touch other surfaces, folds etc. Will vibration cause noise?
That's a very good point, so I'm going to make sure the sheet metal shroud dosen't touch anything. I think I'll seal it to the base with rubber roofing membrane that won't transmit vibration.
To insulate the cabinet, acoustic ceiling tile seemed like a good idea. So I picked up some glass and some perlite panels. THe first thing was to test them for fire resistance and they passed by not catching fire.


Then I glued the glass panels to the 3 sides and the top of the cabinet, then added a layer of perlite to the back and top. The back is adjacent to the basement, the top us directly under the living room floor, the front is an exterior wall and the back is adjacent to the battery compartment. So the top and back are most critical. The front and back are tight for space, so I'll just use the one layer of glass. I'll put some asbestos between the exhaust pipe and the fiberglass for insurance. I'm also going to add a few screws/washers to each panel just in case the glue doesn't hold up.
