There is no one product that suits every application - a basic polyethylene foam such as Climaflex is well suited to domestic applications as it offers good insulation values with a low price and is easy to fit. In applications such as insulating your pipework in the loft or the copper pipes to your boiler it can be used in conjunction with either clips or even a gaffer tape (such as Rhino by Ultratape) for quick and easy installation. For condensation control you are better off using a nitrile rubber which offers a high emissivity finish (ie because it is black) and that is ideal for preventing condensation.
