Insulating a Tank

[TheHabit]

What can I use as insulation for my 20g long glass tank?

I used housing foam insulation board. The reflective side inwards towards the tank.

I use blue insulating foam board



It's behind the foil tape on the tank, but you can see some that's against the wall behind it. Works great and can be covered with fabric if you don't like the way it looks.

regular foam works too. I got some from Joann's crafts.

I used cork board (walmart) in the winter covered in foil tape similar to Argentra.

I use cork as well on my free standing tubs, and blankets on the tanks around the foam board. Winter here can be really harsh and we can't afford to keep the house above 72, so I use all the insulation I can get. It worked, tho. No one's temps dropped much all winter.

IMHO, the more insulation you can put on an enclosure, the less 'hard' your heating sources have to work. That's money in the bank for a student.

I ended up getting Reflectix, it looks like mylar bubble wrap. Its about 1/2 inch thick and I put it on sides and back of the tank with foil tape (wow that stuff is crazy xD). I'm happy with it since it keeps the cool side from getting lower than 78 degrees, whereas before it was getting down to 75-.
Thx for all the feedback

Foam board is awesome.

Edit: I realized you already had something.
