Why are pipes lagged

A very well-insulated pipework system will help cut down on running costs and save ultimately on maintenance. The Thicknesses of thermal pipe insulation used for saving energy can vary, but as a general rule, pipes operating in more-extreme temperatures exhibit a greater heat flow and larger thicknesses are required for a greater potential savings. Lagging can reduce and help limit unwanted noise. Pipework can operate as an amplifier for sounds to travel from one part of a building to another or throughout a home.

Pipes radiate mechanical noise or you can hear the water passing through them, especially if you have thin walls. So by putting something over the top can help muffle that annoying sound, Insulation and lagging can form areally good sound barrier.

When it comes to health and safety exposed metal pipework can reach highly extreme temperatures of hot or of cold. Insulating these pipes means that people are less likely to injure or hurt themselves if they were to come into contact with these pipes. So by adding lagging this can reduce those risks. So, when water freezes, pipes can have the potential to burst, leading to very expensive repair work, so by using lagging around the pipes you can reduce such things from happening.

Pipes in very cold environments can attract water vapour. When this condenses on the surface of the pipe, it can lead to corrosion. It can also potentially cause damp within the surrounding walls. By using insulation or lagging this prevents this by simply raising the surface temperature of the pipe and hence forming a water-vapour barrier.
