Default Keezer collar build - is insulation necessary?

I'm in the process of putting together my keezer collar using 2x12 pine. From you guys who have done something similar - was it necessary to insulate the inside of the wood, or can it be left bare without any issues?

My keezer is inside the house, so there aren't any extreme temperature factors. I have already sealed the wood, so I'm not worried about protecting the wood, but I am concerned if I am going to get condensation on the outside.

I had a 2x4 pine collar on mine last year. It was in my father's shop where the temperatures where a little harsh during summer. I never noticed any kind of condensation on the wood, even on the hottest days (the days where it would condensate instantly on the faucets). However, it could of been because the wood was just absorbing the little bit of it as it formed.

Regardless, I have upgraded to a 2x10 pine collar recently on that same keezer and plan to insulate within the next couple weeks for no other reason then I have seen others do it, and it definitely will not hurt.

Yea I'd have to agree that it won't hurt... I just don't want to have to do it if I don't have to.

I used 2x10's so I could fit a keg on the hump. I think a good seal on the top and bottom are more important than extra insulation. Insulation is always something you can add later when your DIY list gets shorter.

It would pay for itself in no time, I would insulate.

Any quantifiable info for this?

Here is a website with common building materials corresponding R-values. http://www.allwallsystem.com/design/RValueTable.html

Notice all insulation material is greater than the 2" thick soft wood (pine) at 1" in thickness. I don't know how to quantify how long it would take to pay for itself, but with out a doubt, over time it would.

Insulation is not a bad idea. If you are just doing the collar and go, you will probably not notice much loss as you will get temperature stratification in the chest freezer. If you decide to put a fan inside the keezer to promote consistent cooling you will have much more loss. Foam insulation is not all that expensive so to me it really does not hurt to insulate. My keezer is insulated but has no fan yet and it turns on infrequently and never sits through the compressor delay unless I put a room temp keg in it.

I haven't insulated mine, and even with a computer case fan running 24/7, there's been no noticeable difference in our electric bill over the past two or three months.

Of course, with summer coming up, that might be different... but I highly doubt it.
