External pipe insulation

[b9jobber]

I have got to run a hot and cold water feed down the outside wall of my house - there is no way they can be run internally. I shall be using 15mm JG Speedfit pipe.

My question is what pipe insulation would you recommend that's waterproof and possibly brick coloured or could be painted to blend in with the brickwork. The pipe runs are 4m length each with 4 x 90 degree elbow joints. Also, how would I fix the insulated pipework to the wall, and how to insulate the elbow joints.

That's three questions..... sorry

I insulated my condensate pipe, after a year it looked ***t the insulation "crumbled" the zip clips securing it couldn't hold it as it crumbled under them, so it fell off in places, if you really can't run the pipes inside, then take the inside outside and box them in.

In the end I zip clipped a heater cable to it and leave it plugged in 24/7 (my one has a stat on the cable itself)

Many thanks someone-else - I've been toying with that idea. If I box them in, I could always use something like climaflex to insulate them.

I am of course open to other suggestions.

Pretty ununsual situation if you state it's 'impossible' to run he pipes indoors. What is the reason for this?

I'm taking a "spur" from upstairs (bathroom) to a conservatory below I'm about to build to install hand basin with hot and cold feed. The roof line is some 2m below where the existing pipes I'll be running them from are located. I don't want to pull floor boards up, chase out plaster etc to run pipes to new location.

But it would be better if you did.
