How should the insulation level of the induced draft fan be determined?

How is the area for external insulation of the exhaust fan determined? Is there still a fixed value after calculation?
I need to calculate the insulation area for the exhaust fan. Since the exhaust fan has an irregular shape, it’s difficult to determine this area, so I was wondering if there are any reference values available.
There really isn’t any for this; generally, insulation is only applied to inlet and outlet pipes. Is insulation applied to fans to prevent burns? Which manufacturer’s fan should be chosen? Which technician should be consulted for advice?
It mainly involves insulating the fan volute section, with the purpose of preventing burns and smoke condensation. Thank you.
Make it into a square insulated structure to enclose the exhaust fan completely. The thinnest part meets the scald-proof standards, while insulating it according to the shape of the volute is both complicated and unsightly.
Generally, there’s no need to be too precise when calculating the area for external insulation; it doesn’t save that much money anyway. It’s better to estimate based on the overall area and include a bit more margin, treating straight areas as curved ones in such cases
A silicate board is placed on top to give it a rectangular shape; wires are used to secure it, and galvanized iron sheeting is applied over it. Not to mention fans, even large axial flow pumps can have their heat preserved in this way
