Climaflex Pipe Insulation 35mm x 9mm

Where there is not much room round a pipe, Climaflex Pipe Insulation 35mm x 9mm gives 35mm pipework a slim 9mm foam jacket. It is closed cell polyethylene, sold in 2m lengths, and it suits heating and water lines.

The 9mm grade is the slimmest Climaflex. It fits through tight notches, close to walls and inside boxing where thicker lagging will not go. It still cuts heat loss compared with bare copper and gives some frost cover. If the pipe runs through a very cold area, though, a thicker wall is the better bet. That is a judgement for the job, so ask at the counter if you are unsure.

Fitting Climaflex pipe insulation

Thread lengths on as you install the pipe, or slit them and wrap them round existing work. Butt each length up tight to the next. The joints can be glued, taped or just pushed together. Cut with a sharp blade for clean ends. On bends, cut a V out of the foam so it closes round the corner with no gap.

Thicker walls for 35mm pipe are listed under pipes, hoses and insulation.

Common Questions

Is 9mm Climaflex worth fitting on a 35mm pipe?

Yes, even a slim wall cuts heat loss from bare 35mm copper and tidies the run. It is the right pick where the pipe sits in heated space and a fatter tube would not fit.

Which Climaflex should I use on a cold 35mm feed?

In a cold area, go up to a thicker wall than this one. The 9mm tube gives limited frost cover, so keep it for pipe that stays inside the warm envelope.

Will 35mm x 9mm fit through a joist notch?

It adds 9mm all round, so check the notch is wide enough for that before cutting more timber. Keep notches within the limits for the joist, and ask a joiner if in doubt.
