[QUOTE="Volenti, post: 6087271, member: 566487"] Well there's going to be a big difference between using fibreglass insulation as per manufacturers specs, and cramming in as much as you possibly can. The latter will provide a pretty good temporary seal. A more permament, and far messier solution would be expanding foam, which would be superior to densely packed fibreglass insulation when it comes to stopping acoustic pressure. Another option would be bulk closed cell foam, crammed in like the fibreglass insulation. [/QUOTE]
