Greetings! I'm a long-time lurker and thread-searcher, but finally came to a dead end on my search for an answer to this question.
I'm building a long draw (16ish feet), glycol colled draft system. I decided I wanted to use EVABarrier lines and duotight fittings wherever possible, so I knew I'd have to build my own trunk line.
I've got all my beverage and glycol lines (3/8" ID PEX) cut to size and I'm about to zip-tie them together and start the wrapping process. I understand that trunk lines are 1) wrapped in a moisture barrier; 2) wrapped in a cold-transfer, aluminum barrier; 3) insulated with appropriately sized pipe insulation; and 4) wrapped in a barrier tape of some sort (duct tape or black barrier tape).
Micro Matic, which seems to be the standard in trunk lines, sells tapes for all of these (Tapes - Installation Accessories).
My question is: is there any reason why I should use those tapes over store bought plastic wrap (like saran wrap), quality aluminum foil (Reynolds heavy duty), 3/4 thick tubing insulation, and then a cheap barrier tape like duct tape? It's $85 or so after shipping and taxes for those three tapes from Micro Matic; alternative media from the store would likely cost about $10. It's truly a negligible difference when compared to the cost of the system, so if there is some solid reasoning for going with the Micro Matic tapes, I'll do so. I mainly don't want to wait for the tapes to arrive.
Thanks in advance for your input!
