Double-thick walls

[Bullwinkle]

I've heard double (but not triple) thick walls help with insulation. I assume that means if you put double thick walls around your freezer on only 2 sides, that is better than nothing, or does it need to be completely enclosed in double-thick for it to have any effect? Also does it matter which materials? Is it better to have one on the inside and another on the outside?

All materials have the same stats.

The freezer doesn't have to be fully enclosed, every double wall is helping. You can't have a double-thick wall where the coolers and doors are anyway.

Shape of the freezer also matters. Square is best, rectangular slightly worse, weird shapes are terrible.

Room in room is also something that increases efficiency. A freezer inside a bigger house works better than a freezer outdoors (because of how temperature averages between rooms).

+1 to what they said.

Also a huge help to double at least some of the outer walls of the bedrooms, especially in a biome that gets extreme temperatures. Once winter gets down to -35C I lose so much through a single wall I feel like it might as well be all doors lol

Isn't the double thickness over-the-wall cooler in vanilla now?

The AC unit is one tile thick and replaces a single wall. Anything else is modded.
