Armorflex Insulation

Even though it is NOT rated for high temps, it just gets a little crispy on the inside, but does not MELT off like the other Armourflex Wannabe piping insulation does...

I know this because of my solar hippy days...

Funny what happens to things when they are exposed to 350 degree F stagnation temperatures...

That said, I would also not suggest it be installed on steam lines because of the odors and off gassing it would generate.

    Armorflex Insulation

    Can anyone tell me what this type of insulation is? Is it the same as foam pipe insulation?

    Thanks

    There is the cheap polyethylene stuff that is slightly shiny and comes in beige or green that I have seen.

    Armaflex is a brand name but there are others and they are distinctly NOT of the polyethylene variety. Both are "foam pipe insulation" but the Armaflex type is far superior. The k factor is similar to fiberglass but is more flexible (ya think??) and is generally easier to apply.


    Armaflex used to be made by Armstrong or at least I always thought it was. It is now made by ArmaCell in Mebane, NC, perhaps a spin-off.

    ArmaFlex even is a brand name has the "Kleenex" and "Band-Aid" name brand advantage. It is NOT for use on steam lines; use on hot water and refrigerant only. Just in case you were going to go wild on us.

    Hot hot hot, ouch ouch ouch

    The Mebane factory is visible from the interstate 40 as we wave by. Armacell does make stuff to withstand low pressure steam - but you won’t find it at the local home center either. It doesn’t smell noxious either, kind of sweet in a way, but so nice and soft to caress

    Remember though, like Brad and ME warn, polyethylene (coarse and raspy) foam is wholly unsuitable in hot heat. Convince yourself by pouring warm oil from the engine in a recycled plastic milk jug - and whoever is in charge of your garage floor won’t be happy at all.

    I remember of several hot varieties, one is the Armacell HT, 300F continuous use.

    There is also all of the proven rock solid calcium based stuff, like what the space shuttle is made of on the bottom.
