Outdoor insulation for overflow pipe

[Eyespy999]

evening,

I am looking at insulating a plastic overflow pipe 21.5mm? They have some cheap insultion down at wickes but looking at something that will last and not disolve with uv. Any reccomendation please?

Cheers!

Hi Eyespy,
I would recommend this pipe insulation never had an issue with this one.

What's the overflow from?

Good question, but if from boiler I'd go with a thick insulation.
Didn't think of it, good point simon

If it's a boiler 21.5 is too small for external.

Snowhead is right. It should be upgraded really if 21.5mm is ran externally.

Climaflex pipe insulation is rot proof and Non-Hydroscopic, it offers greater thermal conductivity than economy pipe insulation which only has a 13mm wall thickness it has a 25mm wall thickness. You can get it at most DIY outlets including screwfix. It would be good to know what the overflow is connected to though as mentioned above if its from the boiler it is not the correct size for external use.

Hi all thanks for the advice, it is a condensate pipe that is going to be insulated, it was installed a couple of years ago. I am going to be doing a power flush at the customers address and have been asked to insulate the pipe.

Eyespy, you could probably make a bit more money by upgrading it to 32mm. If you check the boiler manufacturer's installation instructions most I've seen insist on 32mm when the condensate pipe runs externally. To be honest, when we fit them we run them through the cavity wall in 40mm and out to the drain. No difference in cost really between them and it's certainly not going to freeze up in Winter!
