Best Thermal Curtains: Choosing the Best Thermal Curtains Can Help You Save Big

Whenever you’re trying to optimize your home for energy efficiency, you need to look at all the angles you can. A few posts ago, I covered The 4 Best Energy Efficient Light Bulbs – Save Money The Easy Way. Today, we’re going to take a look at thermal curtains – what they do, how they can save you money and the best thermal curtains to buy.

Energy efficiency based house modifications need to be thought of in a different way. Considering that you are spending money to save money, it is almost a form of investing. The other interesting thing is that over time, the cost of the item you purchased to save money will most likely pay itself off!

The Problem

Let’s talk about why you would want to consider buying thermal curtains in the first place. Heating a house or apartment costs money every month. The problem is that houses and apartments are not efficient when it comes to holding onto this heat. This means that the heated air (that you spent money on) finds it’s way out of the house through the roof, doors and windows. In a house with poor insulation this is the percentage of heat loss:

  • Walls – 35% heat loss
  • Roof – 25% heat loss
  • Doors, Windows and Floor – 40% heat loss

Most houses/apartments have some form of insulation in the walls and on the roof. However, there is a problem that still remains – the doors and windows. In this article, we’re going to focus on windows. One of the ways to improve the R-value (capacity of an insulating material to resist heat flow) of windows is to consider thermal curtains. Windows have a much harder time blocking heat than walls do.

If you want to learn more about R-value, check out this video. Even though they are talking about insulation, the concept remains the same:

What are Thermal Curtains and How Do They Work?

Thermal curtains are thick curtains with multiple lays of fabric and a layer of foam. The idea is that these layers will block the flow of heat. By blocking the heat transfer, heat loss is cut down considerably. This means that money you spend to heat your home will not be lost when the curtains are in place doing their job. The older your windows are, the more beneficial thermal curtains will be. Even the newest, best insulated window still has a lower R value than the wall of the house.

How Much Can You Save?

It depends on your home set up (amount of windows, age of windows, amount of insulation). Depending on what site you look at, savings can vary between $50-100 per year depending on the type of heating system (gas, electric, etc). Over time, you can recoup the costs of the curtains from your savings.

  1. Hi I have not thought of the importance of thermal curtains before. I can see now that you have described them that they can make a difference in keeping the heat in. I have a front door in my lounge and the window is uncovered. It would be better then if I get a long thermal curtain for it.

     We use low energy light bulbs. We were fed up that we cannot get cavity wall insulation as our house is old and has solid walls. I didn’t realize the curtains have insulating foam in them. Good idea.

  2. Wow, I didn’t realize thermal curtains could be so beautiful!  I’ve always sewn my own, but with the cost of fabric being so expensive, it’s not even worth the extreme effort.  These are so reasonably priced, I can’t resist.  I can justify the cost with all the money I’ll save in heating bills 😉

  3. I have been looking at curtain options for our bedroom and this is the first time I have come across thermal curtains. What a novel idea. I wonder if you can use these curtains all year round or would they be too hot to use in the summer?

    The prices aren’t bad at all, especially if I compare with curtains I see in the shops. The designs are great and I especially like the curtains with the birds on them for our bedroom. The fact that you can save even more money on your heating bills in winter is another great bonus. 

  4. Hi Dave, 

    Thanks so much for writing this blog, I really appreciate you taking the time to share. 

    I have never actually thought of thermal curtains to save money around the home. I myself am a bit of a personal finance nerd so am always looking for ways to make or save money. Funnily enough, my air conditioner unit has been playing up so if I invested in some thermal curtains, I’d likely not need to use it as much. 

    Thanks again Dave.
