Hey Guys,
I highly recommend Auralex Designer Series DTS 114's and DTS 244's studio foam for your studio. It will make your studio look and sound nice.

I built / designed a small 8' x 10' home studio room with floating floors, walls, drop ceiling and vocal booth using :
2"x4"x8' Studs.
Fiberglass Insulation.
MDF.
Birch plywood.
Drywall.
Auralex U-boat Floor Floaters.
Auralex SheetBlok Sound Barrier.
Auralex Designer Series DTS 114's and DTS 244's studio foam in charcoal.
Auralex Pyramids in blue.
Peace.
