Insulation

What method/product do you prefer for pipe insulation?  I have used fiberglass & cover, armoflex (covered on exterior) and fiberglass with PVC pipe.



This must be my sticky point on installs because of the aggravation that ensues immediately upon this task.  Maybe I just gotta get over it, but maybe there is a better way.  Just wondering what everyone else is doing.



Thanks in advance.

    elastomeric foam

    inside & out. used to use armaflex, recently switched to aerocell, which more cheaply complies with WI rebate temp standards (250°) for closed loop pressurized systems. I find it a bit less slidable and stretchable over fittings than the armaflex, though. I slide it over pipe wherever possible, slit & glue where I can't.



    I sense the preslit & preglued stuff is probably a better way than do it yourself slit & glue, but haven't gotten there yet.



    PVC jacketing outside for UV & weather resistance, secured with matching color self-tapping screws. have some doubts about the longevity of the PVC.
