Question:

What kind of pipe insulation is best to use on water pipes to prevent freezing and keep the hot water hot?

I was preparing to buy the pipe insulators and install when I realized there is more than one kind, so which is better the foam or the rubber insulators?

Answer:

The best insulation for the self installer is armaflex brand, which is a very dense rubber that has a special adhesive to join the pieces together, which is great for filling all the inadvertent gaps that will happen as you install itThe secret to a good insulation job is to make sure all the gaps are sealedotherwise it does little good, as it's akin to having a gap under your door that the cold air rushes intoArmaflex also comes in different thicknesses, ranging from a 1/2 thick wall to an 1 1/2 thick wall and it's inside diameter goes from 1/2 piping to 2 piping which will take care of most jobsGood luck!!
