Armaflex Class O Foam Pipe Insulation Coils Nitrile Rubber-15mm-13mm-Wall

Armaflex can be used on any pipe work but is especially suitable for my application which includes solar. The existing foam insulation had melted due to high temperatures, especially near the collector. Armaflex, I understand, is quite capable of withstanding these temperatures. Be aware that it does not have a seam which can be opened up like foam insulation does. So, unless you are threading it onto new pipe work, you will have to cut a seam and open it up. This is easy with an ordinary pair of scissors or a knife: but you may need some tape around it on bends as it wont spring back quite so easily as foam. There was a rubber smell from it for the first week or so, but that is gone now. It is amazingly light to handle and obviously very effective.
