Insulating the external pipes on your property is a good idea, bringing a number of advantages. There are several options for external pipe protection, and by learning more about these you can see which would be best for your home.
Why Insulate External Pipes?
The main reason to insulate external pipes is to prevent the pipes from freezing in colder weather – something that can cause them to burst. Insulating the pipes slows down the rate that the water in the pipes cools, helping to keep them above freezing point. This also has the advantage of saving energy, as it helps keep the hot water at the desired temperature until it reaches its destination.
In warmer weather, cold water can cause condensation in the pipes, leading to corrosion, mould and mildew, which in time can cause structural damage to the pipes. Finally, insulation can even reduce the noise in pipes, helping to create a more pleasant environment.
Choosing Protection
You have a few options for pipe protection, so it is worth considering the features of these to decide which suits your needs. If you are not sure, get in touch with a retailer of pipe protectors such as meterbox.co.uk/pipe-protectors for their recommendations.
One option is mineral wool pipe insulation. This is a fire-resistant material that performs well at high temperatures. It is also resistant to mould, moisture and vermin. However, if it is exposed to rain, it will soak up water, so requires the addition of proper cladding.
Polyethylene foam insulation is lightweight pipe protection that is cost-effective and easy to cut and install with good thermal properties, making it particularly suitable for large-scale installations. It is also resistant to mechanical impact, is waterproof and able to withstand harsh weather, so is a good option for buried water pipes or ground source heat pump pipes.
With exceptionally low thermal conductivity, phenolic foam can provide a high standard of insulation with relatively thin layers. It is also resistant to fire, making it popular in the UK. However, it is not entirely waterproof, so additional cladding would be required.
