What To Look For In Bearded Dragon Tank Insulation

When you hear the word insulation, you may imagine the foam or pink panels you put between your siding and the walls of your house.

While the idea is solid, you don’t need to do anything this extreme for your beardy.

There are three main ways to trap more heat in a bearded dragon tank.

Thicker Layers – By adding a thicker layer, the heat doesn’t escape the sides or bottom of the tank as easily.

This will keep the heat in better and make the tank overall warmer.

This is the method most like the insulation analogy above.

Covering either the bottom or the sides of the tank with thicker material such as cork or a reptile carpet will make a noticeable difference in the temperature of the tank.

Solid Top – Most vivarium tops are some form of secure screen top.

And most of the time, this works fine.

The screen top will even help keep fresh air moving in the tank.

But if it’s just too cold, this is a huge source of heat loss.

After all, warmer air rises, and with a screen top, a lot of heat is escaping.

Replacing this top with a glass or other solid material will go a long way in keeping things warm.

Under the tank heater – Some may argue this doesn’t qualify as true insulation because you’re just adding another heater.

However, the heat rising from the bottom will do more to heat the colder lower parts of the tank in colder weather.

This doesn’t mean you should replace your basking light.

The beardy will still need it.
