Air Source Heat Pump Outdoor Pipe insulation.

[CCoomber]

Hello, So I had a ASHP installed over a year ago on a scheme howver the installers neglected to insulate the outdoor pipework between the unti and the house. I've read that ideally it needs to be high quality O type, UV-resistant, closed-cell insulation with a wall thickness greater than 19mm and I wondered if anyone here who maybe worked in the business had any go-to pipe lagging (along with tape and adhesives etc) that they could recommend.

King regards.

Primary pro is generally regarded as one of the best types to use.

I think Armaflex is another well-known branded insulation product...

Kooltherm with a cladding is another good choice
