Adding High top: DIY insulation or pre-installed?

[JJPDX]

Hello, looking to add a 24in high top to my Chevy Express 3500 Extended. There are several options to choose from, see below, but the one I'd like some feedback on is the installed insulation.

Does anyone have experience with the insulation as installed in a high top by fiberine? I am a complete noobie and would by interested in it being done with all at installation. But if its generally insufficient or low quality, then I'll be back in a few months with lots more questions as I do it myself!!
Thank you, jj

I have installed high tops(not Fibreine). I have insulated high tops and shells/caps. what is very important is to have a fuzzy outer surface. if it's not fuzzy it will rain on you under certain conditions. highdesertranger
