Yesterday I visited an acoustics shop, where they sell everything that has to do with sound deadening, house, boat, car you name it, they'll have it.
and ofcourse I couldn't leave empty handed, so I picked up
4 sq meters that'll be about 13 sq foot of Vibraflex for the floor
2 sq meters (6,5 sq foot) StP Gold for the doors, rear wall and fire wall.
I just realized that might be a bit to little..but I'll find out as I'm installing it.
Hopefully I'll get to it this weekend, because now where having decent whether and I'm busy smoking 8 pounds of Livar Ribs..yummie!
