2 full sheets, 3rd sheet got about 9" cut off one end before I realized it was 5/8" instead of 1/2" - have both pieces. Retails for $23.48 a sheet at HD. $40 for all 3 5 full large tubes of green glue soundproofing plus a 6th with a bit left in it. Retails for $15 each, take all for $40 About 1/3 of a tube of the white soundproofing for around electrical boxes and wall/ceiling joints - tube is split and partially hardened, but if you open it right up, might be some useable stuff inside. This one is free... Need it delivered? $20-30 depending on where you need it, I'm in Chemainus
