Cold Water Applications
The scale of damage and financial cost of water pipes burst due to freezing can be devastating. Insulation offsets pipe freezing and is highly recommended.Domestic cold water in the UK is piped directly into homes from a central supply. As water pipes enter a building they create weak points, known as thermal bridges, in the building fabric through which heat is lost. Condensation can also form on the cold surface of the pipe inside the building.
Cold water pipe insulation plays an important role in preventing these problems but the prevention of pipe freezing is by far the single greatest reason for insulating cold water pipework. Water left stationary and exposed to sub-zero temperatures will eventually freeze. As pipes freeze water expands and the pressure exerted is enough to either burst pipes along the length or to break pipe connections apart.
By greatly slowing the rate of freezing insulation makes pipe freezing much less likely. Insulation should be present along the entire pipe length and should have the following properties:
