If steam, model energy codes and good practice require 2 inch thickness and if hot water, 1-inch thickness for the pipe sizes you seem to have. Know that the first inch knocks the heat loss down to about 1/6th of what it would be bare. If two inches, 1/12th. Point being you never stop heat flow, just slow it down a bit.Get Price
