It says Wooden Buildings such as Insulated Wood and Black Ice Reinforced have Cold insulation ability, but I never notice such things.
And same as Stone Brick and Reinforced Stone buildings, it is Heat insulation in their description, but I do not feel specific change of temperature of my toon.
Also heard some people saying ‘they’ mentioned about new t2/t3 buildings for Swamp area like they released new t2/t3 buildings for Highland area before.
However, I guess that’s not gonna be happened, and they locked the contents and are already about to launch the game.
But anyway, I wouldn’t mind even if they remove the effect of temp insulation from Stone type/ Wooden type that doesn’t seem to help much.
