Any insulation will help, the weather has been colder than we are use to, normally that size pipe will not freeze, the idea is the boiler stores the water until it has enough to release in a batch so it will not freeze, in same way our rivers don't freeze.
You want removable insulation, as if it does freeze need to get access with hot air gun, I was lucky the sink pipe ran alongside so lagged both together.
