How does the foam rubber pipe insulation do its job?
I've been puzzling how modern pipe insulation works. If the
temperature in a room is constantly at 0 dec C, then surely EVERYthing
in the room - pipework, insulation etc - is at the same temperature?
(Given that there is no hot water flowing through the pipes.)
So what actually does the foam insulation around pipes do to protect
them?
