It can prove a prudent decision to insulate copper radiator pipes, given that they can be susceptible to freezing if and when the temperature drops below freezing in the colder winter months.
Plus, in many instances, copper water pipes are positioned beneath the floorboards which would tend to put them at a greater risk of freezing still.
Water pipe insulation materials typically boast strong resistant properties as it pertains to thermal energy movement, so the insulation of copper radiator pipes can prove a massive help in combating the freezing of the pipes. Thus, your hot water radiators can continue to operate as normal when you need them the most.
