By design, your furnace / kiln can become more fuel efficient by cutting heat loss through the lining. The simple example below will show % heat loss savings achievable by the addition of a 50mm thick veneer or to the conversion of dense refractories to fibre (where suitable).
Simply select an operating temperature and furnace lining representative of your existing furnace / kiln.

Select Your Furnace Operating Temperature
900°C
1050°C
1150°C
1250°C

Select Furnace Lining (Similar to your existing lining)
200mm Fibre Lining
230mm Dense & 114mm Insulating Brick
