When pipes freeze, the first thing you'll notice is low or no flow. If they stay frozen for too long, or if too much water gets frozen, you'll end up with burst or weakened pipes. Insulation slows down the flow of heat from the water in the pipe to the cold air around it. Keep in mind that it doesn't stop it entirely and depending on how long the water in the pipe remains stagnant, it will loses heat. For the most part, however, insulated pipes keep the water temperature above freezing. The colder the winter temperature where you live, the more insulation you need.
