Blast Furnace Insulation

Blast Furnace Insulation is a more compact way to insulate your Blast Furnace. Rather than placing sheets around the chimney, Blast Furnace Insulation is applied directly to the Fire Bricks using ПКМ. When broken, the insulation and bricks drop separately.

Crafting insulation requires the same number of Wrought Iron Sheets that would be placed around a single fire brick block.
