50mm thick 2400mm x 1200mm panels, 48kg/m3 density, 4 in a pack, $212.
Piece of cake. If you cut these panels into symmetrical quarters, you get 1200 x 600mm (4' by 2') panels, so you can turn those 4 panels into 16 panels.
This is equivalent to getting 16 panels of 2" thick 4' by 2' Owens Corning 703 fibreglass. Or 8 panels of 4" thick (100mm) if you're interested in doubling the thickness which is what I'd recommend for bass traps.
So that's like $212 AUD for 8 panels of 4' by 2' Owens Corning 703 at 4" thick. Not bad at all.
