yes, insulation options are encouraged.
I have a feeling there is a house being knocked down just down the street from me (large dumpster in the yard and it's condemned) would it be a good idea to grab some of the insulation from that if i can?
I'd prefer those sheets of styrofoam but even on kijiji they are still like $15/sheet
I figure i can at least insulate it cheaply this year and worry about electrical/heating next year or the year after
thank you for the compliments fellows. Without the handy work of Apesteguy that bench wouldn't be half the bench it is.

how would a fellow go about calculating the square footage that i need? do you insulate the roof?
seems like each bag covers from 50sq. ft to 120sq ft. (depending on bag) just some quick math, 8 foot tall wall, 18 feet long that's 432 feet of wall space, albeit i don't know if that's the correct way to calculate it or not. but if that's the case i would need 4 bags per wall @$60'ish/bag would need to cover 3 and 1/2 walls basically plus roof.
im looking at roughly $1000 for the walls and that's without the roof.

That's right but your math is wrong 8x18=144 x4 =576 - your doors and windows Yes do the ceiling too 18X16 = 288. Hrm code calls for R-24 for the walls and R-40 for the ceiling but you don't have to go that much ( I did ) Shop around. I saved alot of money on Mine by doubling up r-12 for my walls , and shopping around You need to know your stud spacing too. It's either 16 in centers or 24. If it's 24 then you buy R20-23. The first # is r value and the second is stud spacing
You'll need to strap the ceiling first so you have something to hold the insulation up and something to staple the vapor barrier to. About 15 cents +/- a foot, you'll need 234 feet. 13-10 ft pieces and 13-8 ft pieces. Rough in the ceiling wiring before installing vapor barrier.
Any time you want virtual money spent let us know.
My garage is only 20x20 and it gets lots of use. It's a little short for the 4 door Dakota. I had planned to extend it deeper this year but time ran out.
