I need your help. We recently expanded the server room size and also installed APC InRown ACRD200 cooling. Unfortunately, general contractor did not sound proof the room in the way that it should`ve been done. The room is approximately 260"D x 100"W x 105" H, there is also a drop ceiling with 16" tiles. Above the drop ceiling there is another 3 maybe 4 feet of space.
We have 3 or 4 plenum vents in the ceiling also. Above the drop ceiling of the server room there is no drywall surrounding the server room perimeter at all. So the noise travels above the ceiling, as well as through those plenum vents (that are not being used) and around the door as well.
I spoke to a one of the vendors, they recommended that I first seal around the door then cover the ceiling with sound proof material (or tiles for that matter). Their cost was a bit high and I was wondering if somebody could recommend a brand of tile or material that I could buy myself and install it.
Ultimately, I may need to install the walls above the sever room ceiling surrounding the entire server room perimeter, however if I was to get contractors that have already screwed up a couple of times, I might as well do the basic work myself and save the 3-4 grand... Any suggestions on materials ?
