High temperature pipe insulation


I am frying my insulation on my solar hot water system even though it says it is for high temperature. It is the polyurathane insulation.

Is there another insulation I can use that will handle 220 F maximum temperature?

Armaflex makes a high temp insulation. It can't remember the name. Google it.

You can use "Great Stuff" foam in a can. It goes up pretty high and has outstanding R-value. The down sides are: It takes FOREVER to put on, it looks shoddy, and you can't expose it to UV. It will turn brown and brake down if exposed to sunlight. I've heard it can be painted with a UV rated paint that is breathable.

Well this is out then cause the whole thing is out side in the high desert sun and with the altitude and over 300 sun days a year it would be difficult to cut out the UV rays.
