Pipe insulation, aka pipe lagging, is used to insulate associated pipework to prevent freezing. Fitted around water pipes, pipe insulation prevents pipes from freezing and bursting. They also keep heat in the pipes, preventing scalding and can have a range of acoustic properties, reducing the noise of the pipework.

Most commonly used to insulate central heating pipework in loft spaces, it can also be used to prevent moisture from building up on your pipes.
