Pipe Lagging / Insulation.
Poorly insulated pipework could be costing you up to 20-25% more on your energy bill.
Are Your Hot Water Pipes Costing You Money?
With the rising cost of energy bills, both commercial and domestic customers are looking for smarter ways to bring down their energy consumption.
The benefits of well insulated pipework
One area that often gets overlooked are hot water and heating pipes and it’s estimated that up to 20-25% of energy is lost from poorly insulated pipes. In a district heating system, this can have a major impact on profitability and efficiency and is easily fixed by a pipe lagging installation.
Insulating your pipework is also extremely beneficial in cold weather, as it will stop your pipes from freezing when temperatures drop below 0°c. Frozen pipes can even lead to further damage such as cracked pipes and loose valves due to the expansion of water when it freezes. So if you want to save money on your energy bill, improve the efficiency of your central heating system and prevent damage to your pipework, pipe lagging is essential to your property.

Pipe Lagging FAQs
Your questions about pipe lagging answered
Pipe lagging can save up to 25% on your energy bills. The precise amount you will save depends on the temperature of the property the pipes are located within. If the pipes are in a property that is already considerably warm then the amount saved will be less, if the property is considerably cold then you will save more having your pipes lagged.
If pipes lagging is installed correctly and the pipe lagging used is of a high quality then it should stop pipes in cold areas (such as loft spaces) from freezing. If you live in an area with extremely cold temperatures then pipes may still freeze even though they’re lagged but for properties in the UK this shouldn’t be an issue, as we don’t experience the extremely cold temperatures of other countries despite our unpredictable weather.
Cold water pipes aren’t lagged to save money on energy bills as there isn’t heat from hot water that need to be retained. Cold water pipes are lagged to prevent them from freezing in cold areas of the home and in cold weather.
The answer to this question ultimately comes down to the foam and fibreglass being used. If you are using the pre-cut foam rolls then it will not normally have as high of an R-rating as fibreglass but if you are using spray foam then it will most likely have a R-rating higher than fibreglass (the higher the R-rating the better the material is at insulating). There are many different brands and products of foam insulation and fibreglass, some products have been developed to boast a higher R-rating than their predecessors which is why there is no definitive answer. You also need to consider other factors such as ease of installation: spray foam will need to be installed by a professional (making the cost higher), pre-cut foam rolls and fibreglass can normally be installed yourself (making the cost lower). We do always recommend having a professional carry out the work regardless, to ensure the lagging is installed correctly and you are getting the most out of your pipe insulation. You will also need to consider material cost: pre-cut foam is normally the cheapest, spray foam is the most expensive and fibreglass falls between the middle of the two. When choosing which pipe insulation to use, you should weigh up the R-ratings alongside the installation and material cost to find the right one for you.
