We just finished building a home, and I prewired an equipment closet upstairs for handling all of my networking, home theater and whole home audio equipment. It looks like this:
All the single and double gang boxes are standard open-backed low voltage gang boxes, and the triple gang is a normal Carlon high voltage box. The back of this wall is attic which makes getting to things to wire them up a breeze, but also means that it's getting incredibly hot in the closet.
There's insulation on the walls that I cut away a little bit to pass wires through, and I've stuffed insulation in the low voltage holes where possible.
Even with the insulation, the outlet covers themselves are probably about 90-95 degrees on a hot day (110 or so in the attic). What are my options for insulating the low voltage brackets? Cramming insulation in there seems to be doing very little.
I know on the Carlon triple gang I can use expanding foam, but I'm a little hesitant to do that until I'm absolutely positive I won't need to make any adjustments to the speaker cable. Do I have any slightly less permanent options there that will still improve insulation?
