What proportion of the total construction cost does insulation material and its installation account for?

RT, what proportion of the total investment in the entire installation does the insulation component account for?
The proportion should be very small; it’s estimated to be at most 1-2% perhaps
The question posed by the original poster is confusing; could it be clarified? I have been involved in several projects, and in one of them, due to the presence of reaction processes along with very high temperatures, all equipment and pipes needed to be insulated, and moreover, the insulation layer had to be quite thick； Another project is a system that operates at room temperature; in such cases, the two pipelines related to utility services need to be insulated. Would the cost of insulation materials for these two projects be the same? Moreover, the cost varies significantly depending on the temperature-regulating material used; asking such a vague question makes it impossible to provide you with an appropriate answer.
Let’s look at the project type. For ordinary chemical projects, it’s usually less than 0.5%. In cryogenic projects such as LNG receiving stations, the proportion of insulation and heat retention is relatively high.
