HVAC chilled water lagging

[EngineerCarl]

Hi There
Does anyone know of an easy install, even a spray on version, of lagging for a large chilled water network. Currently we have armaflex but I need to start changing on difficult geometry pipes.

Any help would be much appreciated.

i can hardly imagine easier installation than armaflex, you put sleeves on, than seal the ends.

I like to spec foamglass preformed pipe insulation - just be lucky you're not installing that.

Spray polyurethane foam (SPF), closed cell 2 lb, might do the trick.
