Pipe lagging

Remember my concerns about freezing pipes? Well, today, I spent just over 5 quid on some pipe lagging and protected all the hot/cold pipes I could get access to under the kitchen cabinet and double bed. Obviously I don't need to lag the central heating pipes as the water in these have antifreeze added but I may extend the lagging to some of the hot/cold water pipes I can't see. These are under the boxing that run along the edge of the floor on the stbd side and a few short ones in the engine 'ole. This is probably 'overkill' but I'd rather be safe than sorry.
