tank insulation

[henfruit]

I just got my vigs 40 up and running.With 2 500 gallon tanks.Well i think it is time to insulate the tanks are up to 160 amd the garage is turning into a sauna. thought of spray foam? aslo if they were wrapped with fibergass 2 layers i think then use boat shrink wrap to cover them and make a nice clean sealed unit?

I built a wall around mine and am getting ready to blow cellulose around them in a little bit. they sure make some good radiators.

I boxed in with 6"+ of fiberglass, 2" of foam board. Your idea sounds good. I suggest aiming for R30-40 unless you want some heat loss into the storage tank space.

Cellulose insulation is an effective insulator, affordable, and relatively easy to remove and replace if you ever need to get back in there.

I foamed mine. Not the least expensive but it is like turning them in a thermos bottle. Mine are also in garage space. Nice during winter but does get hot in summer. This summer I'm planning to box mine in. It has been mentioned that foam can cause issues during a fire so good idea to box in anyway.
