What materials for insulated tiles?

[Cryten]

Hey Ive been looking at the detailed information for materials that can be used for insulated tiles. I had thought from community knowledge that granite was best (excluding abyssalite). However thats stats indicate that sandstone has a slightly higher heat capacity (good for slowing down heat reaching temperature transfer thresholds) and has a lower thermal conductivity (transfers heat slower).

So doesnt that make sandstone a better insulator?

Stats:
Sandstone - specific heat capacity 0.8 (J/g)/K, Thermal Conductivity 2.9
Granite - Specific Heat Capacity 0.79 (J/g)/K, Thermal Conductivity 3.39

Am I readying this wrong? I could swear higher conductivity allowed faster heat transfer.

I think about it like this:

Thermal Conductivity is the pump, and Heat Capacity is the resevoir. The larger the Heat Capacity, the larger the resevoir. The higher the Thermal Conductivity, the faster the pump works.

So in the case of insulating, you want to use a material that has both a high capacity and a low conductivity. A big resevoir, but a slow pump. Between the 2 materials, you'd want to use Sandstone.

As for Granite specifically, it just has a lot of useful properties overall. Other than Abyssalite, it is the strongest Mineral, able to support very large amounts of pressure. It provides a 20% bonus to positive Decor, or reduction to negative Decor, for any item built out of it. And it's relatively abundant once you leave the starting area. So it doesn't sururpse me that someone somewhere made a fuzzy statement that made it sound like Granite was good for insulation.

Huh so that means the starting mineral is the second best insulator in the game.

use abysalite, is perfect. But if you don't care to do micro management, you can try something like my vaccumm wall and vacuum airlock system, with any of the material you want to use you can have a thermal conductivity to zero
