How To Attach Thermal Lining To Your Existing Curtains


Do you have some spare time on your hand? Would you like to spend the time adding a bit of practical benefits to your furnishing, while add the finishing touches to your summer décor? We have just the idea for you!

Your curtains often take the central stage in your design concept. However, there is more to curtains than just aesthetics. Curtains cover the entire frame of the window, providing it with enhanced coverage. This single fabric design offers you a wide range of benefits, like privacy, insulation, and light-control. For breezy summer conditions, a lighter fabric might be just sufficient. But when the chill sets in, your normal curtains would become a feeble barrier against the freezing conditions outside. As a result, your heater will have to work very hard to keep your room warm, burning precious energy and clocking up a big bill for you.

Adding a thermal blind lining to your existing curtains would go a long way in enhancing the functionality of your curtains. It would be a great use of your space time, as it will allow you to make big savings on your energy bills. So, let’s take a look at how an extra thermal lining might help you.

How do Thermal Linings make Curtains More Effective

Energy Efficiency: The biggest benefit of adding a thermal lining to your curtains is achieving heightened energy efficiency. If you are wondering why your heater is using up a lot of energy to keep your rooms warm, the windows are the primary culprit. Most of the heat-loss or gain happens through your windows. So, whatever covering you put over it, is going to play a decisive role in the energy usage. Replacing windows, or even replacing the existing window treatment solution would be a great expenditure. So, why not go for a bit of DIY and add an insulating layer on you existing curtain?

Adding a thermal lining to your curtains would not only allow your curtains to trap the heat in, it will also keep the cool air within the room when the weather starts to heat up. The money you save on your energy bills will be definitely worth it.

Light Control: A thermal lining would also cut off light to a large extent. With a very thick layer, you will be able to get a room darkening effect. Cutting off light also aid in keeping the temperatures down. As the interiors get less light, your room will cool down naturally, with little or no help from the cooling system. While you save money during the day, you will also be able to enjoy a glare-free TV time with family and friends. This is equally useful in bedrooms. If you are a shift worker, or light-sleeper, the room darkening effect would be a great benefit. Now, you can enjoy a sound sleep without intrusive presence of the sun.

Sound Dampening: A thick curtain is also very useful in cutting of noise. If you live in a noisy neighbourhood, you will find this feature very helpful. Whether you are reading a book, or just enjoying a peaceful time with your family, the noise from the busy street would be extremely annoying. Adding insulating blinds, or a thermal lining to your curtains would reduce the noise, giving you back your peace and tranquility.

How to Add a Thermal Lining to Your Existing Curtains:

A little planning ahead and a bit of time is all you need to give your curtains a brand-new lining. The first thing you need to do is purchase enough thermal lining to cover the whole curtain. You will also need to put fusible tape on your shopping list.

Thermal linings are usually made up of varying layers of polyester and acrylic thermal coating, which adds extra insulating properties to the curtain.

Fusible tape is synthetic material which melts when heated. This is widely used to join to pieces of fabric. When placed between two fabrics and heat is applied, the material melts and helps attach the two fabrics. It is very different from weaving or stitching.

Now let’s get down to attaching the thermal lining to the curtain.

You will need:

  • Thermal lining
  • Fusible tape
  • Scissors
  • Iron
  • Pins

Step 1: Once you have got hold of the lining, cut the lining to match the size of the curtain.

Note: If you have tab or ring curtains, cut the lining piece with a ½ inch difference all the way round. If you have a curtain with grommets, measure the lining from the bottom of the holes, and with ½ difference from the bottom and the sides.

Step 2: Place you curtain on a flat surface, preferably on an iron board.

Step 3: Place the non-paper side of the tape along the top border of the curtain.

Step 4: Use the iron to fuse the tape to the curtain material.

Note: Take care to heat the iron following the instructions or the heat-setting recommended on the tape package.

Step 5: Repeat the same process on the left and right side of the curtain.

Note: Do not take the paper off the tape.

Step 6: spread out the curtain on a large, flat surface.

Step 7: align the lining on the curtain, to make sure the sides match nicely.

Step 8: use pins to secure the lining on the curtain.

Step 9: Remove the paper on the tape.

Step 10: Place the two layers on the iron board.

Step 11: Heat up the iron and place it on the liner and take the whole tape off. This would allow the liner to fuse to the curtain along the strip previously occupied by the tape.

Step 12: Repeat the process for the right and left side of the curtain. Now your thermal lined curtain is ready for action. Just hang them back onto the rails and enjoy a much more comfortable ambience in your room.
