Pipe lagging is a great way to lower your energy bills. It’s a simple DIY project, and you only need the basic tools. The heat lost in un-insulated pipes can lead to high power bills and this is why you should lag your pipes. It ensures energy efficiency. Below is a guide on how to save on energy bills by insulating your pipes.
First, You Need to Know the Pipes that should Be Insulating
Before you proceed to insulate your pipes, it is advisable that you know which pipes should be lagged. This will help clear any doubts.
- Outside pipes – These pipes are vulnerable to environmental factors such as cold weather; therefore, lagging them is a great idea.
- Pipes in lofts – It can get pretty hot or cold in your attic. If you have pipes there, then they can be affected by the weather. They too should also be insulated.
- Hot water pipes – Irrespective of where they are located, hot water pipes need to be lagged. This ensures that no heat is lost when the hot water is transferred from one part to another.
The Type of Pipe Insulation for Lagging
The next important thing that you need to familiarize yourself with is what insulation material you should use to lag your pipes. There are different types of insulation material, and each does have its pros and cons.
The most commonly used type of insulation includes;
- Polyethylene foam (mostly used)
- Pipe wrap insulation tape
- Wool pipe insulation
- Asbestos insulation
How to Lag Your Pipes
It is a relatively easy process provided you have the right tools. You will need a utility knife, duct tape, a tape measure, and the insulation material. Once you have all the materials at hand, you can proceed to split the insulation and feeding it around the pipes.
As you do this, push the insulation firmly behind the pipes to ensure that the split meets evenly. You can use duct tape to ensure that the insulation snugly fits the pipe.
Be careful when joining the pieces of insulation. This is because if there are leaks, then heat will still be lost. Always ensure that there is an airtight seal on the joints. If it’s possible, you should get your hands-on special insulation tape. It is more effective in insulating your pipes.
In sections where the pipes are fixed to the wall with clips, as accurately as possible, cut the insulation to accommodate room for the clip. Don’t try covering the clips with the insulation as this will expose your pipe to environmental elements.
You will also come across right-angled pipes. In such an instance, cut the pipes at a 45° angle on the ends and join them together to form the perfect right angle. You can cover any spaces with duct tape. This technique should also be used on T-junctions in pipes.
At the end of your project, if there are any openings. Use duct tape to cover all of them.
Lagging your pipes is an easy task that you can carry out during your free time. It is a rewarding and cost-effective project that will ensure you save on energy bills for years. If you happen to continue accruing high energy bills, heat loss or frozen pipes, then don’t hesitate from bringing in the professionals.
