@balthazad You are correct, solid objects insulate poorly compared to pockets of air. That's why you aren't supposed to compress floofy insulation.

That being said, it makes even less sense how vanilla works. But then again, it's just a game. If we wanted more realism, caves/underground bases would never get above 55 degrees Fahrenheit and the roof would impact heat distribution.

just stumbled over this mod and have to say something.
if you want serious insulation, you build only 1 tile thick walls, but then have 1 row empty and then another 1 tile wall. that's how insulation works irl and so it does ingame. if you add another layer with this mechanic, you will have about 0 heat exchange. that being said, ofc it's space-demanding, but "wall-to-wall" structures aren't supposed to isolate.

@Miha_metan it should work with anything that can separate rooms and doesn't have it's own temperature. So it should work with any modded walls, but not with wall freesers.

@Kusko25 here's the update for 1.6.

Any plans for 1.6?

Wait, thick walls move temperature to the outside temperature? No wonder I'm having trouble keeping my underground bases heated.

does this mod work with modded walls? sos2 ship hull, architect module log wall, hedge..

no heat loss through walls seems excessive (0.1 for 3 and thicker if you don't want to do a formula) but i'll definitely give this a try as i find the vanilla situation silly

@snake This mod only stops temperature change through walls, I think you still exchange temperature through roofs, Thick roofs are more insulating than the constructed

i used devmode, built 7x7 again with square in the middle, this time no green square around the room but the room still changed temperature

7x7 i meant* sorry, 3 cells thick wall

this mod doesnt seem to work for me for some reason. i built 5x5 square with 1 empty square in the middle, built roof under every single square and built it out of wood and the room still changes the temperature. when i used "Draw rooms option" the 1x1 room that i made in the middle showed green square directly to the right of it. i dont use any temperature mods. no errors in the log

Does this conflict or work with the Insulation mod?

@_♣Caligula♣_ my guess is no. Celsius changes how temperature works too much for my small change to affect anything.

Does this work with celsius mod?

@Vexacuz it is part of the game, it just doesn't work as well as it should. The thicker, the better is as it should be.

Creg's wrong, firstly animal flap doors aren't any better than any other door at this it's a common misconception, just use a wooden door because they are faster and so on. Secondly you should leave a gap between the doors to create an airlock. There are numerous reddit posts about it where people tested this.

And yeah like others said, 2 thick walls do insulate better in vanilla but not any thicker, which I assume this mod changes. It's just this mod's wording is a bit misleading, so no none of you are going crazy.

all you need to keep freezers cold is an animal flap door in front of or behind your door for entrance into the freezer

I, too, also tought this was part of the game.

So much material wasted in previous runs...

@Z Catto! Two thick walls do infact work. But three+ isn't properly accounted for. Freezers with double thick are basically the best you can do for insulation.

Thank You

Finally this has been addressed but as @Z Catto! said, I thought for a long time that this was base game mechanics and could never figure why freezer rooms were so hard to keep cold.

I feel cheated for some reason.

i actually thought this is how basegame just worked D: all my chunky freezers will work better lol

@Hoki it ignores fog of war, so if there's empty space you'll have draft from that wall, even if you can't see behind it.

i have to ask the other way around - how does this interact with undiscovered areas in mountains?

would there be insulation happening and then basically break as soon as the area is uncovered?

@Vulkandrache yes. If you turn on development mode and switch on "Draw Rooms" in "view settings", then it'll highlight cells that your room equalizes temperature with, which without this mod happen to include fog of war cells around the room.

Wait, does that mean the walls are normaly counting the fog of war as outside in terms of temperature transfer?
