Armaflex Pipe Insulation Lagging Black Nitrile Foam Class O 2m-22mm-19mm-Wall

This is a good quality pipe lagging that is easy to cut and easy to install. It’s also waterproof, as I discovered after finding a puddle of water in it that was coming from a small leak I would never have spotted without it!

I used this to replace the cheaper lagging on the condense pipe on the outside wall to stop it freezing so far it's done the job well.
