Where does everyone buy their 2" thick foam for keezer collars?

Best price, easiest to get? I am going to need a bunch.
 
Big box. Probably comes in a 4x8. I got mine from remnants at work on the cheap! You only need a single layer so amount depends on the dims of the freezer and height of the collar. After foaming mine, I applied foil tape.
 
I used the foam insulation that they sell at HD or Lowes for garage doors. Easy to cut with an old kitchen knife.

I am doing a long duct to a coffin. That is why I need more than usual.

For some reason I remember HD either not having 2" or it was stupid expensive. I will look again.

Thanks for the help.
 
Lowes carries it 2" Styrofoam in 4x8 sheets. Has foil reflective barrier. Be sure you look at all the options, there are a number. There are also some packs of pre-cut foam in the insulation area of the store.
