Aluminium covered pipe insulation

[MOSSEP]

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.

Used to use subby. It's like tiling... Pipework can be amazing and function better than spec but crack handed lagging makes it look DIY

all that's needed is a bit of patience and a mitre box.
