Where can I get suitable pipe insulation for exterior use? I've been told the EA code we're getting on our boiler for a couple of days could be due to freezing in the condensate pipe.

Had it with mothers boiler, had to heat pipe with blow lamp to get it working again, it seems reason was pipe to small, can't remember sizes, but seem to remember went from 25 mm to 50 mm, and this cured the problem.
