Where do you guys source the aluminium / silvery looking pipe insulation from that you see in commercial jobs? My wholesalers seems to struggle when I mention it.
You can't buy it formed.
It's produced by Thermal insulation contractors for thier own use.
You may be able to buy the flat dimpled sheet from a Non ferrous metal supplier, but you'll need all the formers to bend it and make the junction pieces.
Also you'll need the end trim pieces.
All the plantrooms I see used to have Dimpled covering, but as upgrades happen nowadays it's all foil internally and butyl covered externally, except where it needs access.
Chilled water is shyster, the chillers and external stuff always looks a mess. The plastic wrap is good as birds can't peck it to death and it's a bit more durable than naked armouflex. Most of the "plant" rooms are like toys compared to some of the stuff others play with 90 - 200kw so a massive room with a sissy boiler in corner or a few domestic units out of wall!
