I would like to ask whether an oven room still needs external wall insulation?

It is a drying room with dimensions of 5000*4000*2300; its walls are made of 240-mm thick red bricks, and the ceiling has a thickness of 240 mm, being cast in place. Heated by 4 kilograms of steam. Maintain the internal temperature at 90°C. In South China. In other words, the minimum temperature is also above 0°C; it’s not clear whether it’s necessary to cover the exterior walls with perlite or rock wool panels as an additional layer. If the energy loss is not significant, no insulation work will be carried out. I’m seeking advice from everyone. Are there any that can calculate? Are there any that can’t?
I think it is necessary to cover the outside of the wall with perlite or rock wool panels to reduce energy consumption and save energy.
The key is to have the calculation data. It is an era when labor is expensive and energy is cheap. Haha
I think it’s still necessary to provide insulation; using centrifuged insulating rock wool or perlite boards to cover the outside is the best approach. Aluminum silicate works too.
