It might seem like the start of a Hollywood film, but achieving this setting is harder than you may think.

For many Americans, they are blasted with intense sun rays in the early hours and struggle to get back to sleep because of the bright glare seeping through their current blinds or curtains.

This problem, along with many other issues homeowners face, can be solved with a pair of thermal curtains.

So, what are thermal curtains? What are their benefits? And do thermal curtains work in reality?

These are three questions that many homeowners and America’s renters are asking – and ones we will address here.

What Are Thermal Curtains?

Thermal curtains tend to be thicker, denser, and heavier than regular curtains. These properties mean they are great for keeping light out and also heat in.

Many pairs of thermal curtains will include additional layers of materials, most often fabrics or sometimes even acrylic foam.

These additional layers help the curtains complete their main function to maintain the heat of a property.

It has been estimated by the Energy Information Administration (EIA) that up to 33% of heat within a USA home is lost through doors and windows.

Double and triple-glazed windows go some way to preventing heat from pouring out of homes and increasing energy bills, but thermal curtains provide another layer of defense to keep the heat in and the cold out.

Yet, it should also be noted that thermal curtains are not just for the winter months or colder states. Texans and west coast dwellers will also benefit from thermal curtains during their hottest seasons because these curtains also keep the sun’s rays at bay to maintain cool temperatures indoors.

Thus, thermal curtains do not just keep heating costs down, but they also save energy by keeping air conditioning costs down as well!

Other Benefits of Thermal Curtains

By explaining what thermal curtains are, it is already evident that their main benefit is that they can maintain optimum temperatures in homes, and this has a knock-on effect on energy bills, saving the planet and people’s hard-earned dollars.

Yet, there is more to these curtains than this. They also:

#1: Reduce Noise from Outside

Thermal curtains also contribute to reducing noise from outside within the home. For people and families living in busy areas or near busy roads, they can help them to relax and get a better night’s sleep. Thick windows are more effective at this but thick curtains can help too.

#2: Keep Out the Light

As the opening paragraph of this post alluded to, many Americans have to deal with bright sunlight waking them up earlier than they hoped for.

Thermal curtains are better at blocking these rays from disturbing your sleeping pattern because they are thicker with more layers of materials.

#3: Look Just as Appealing

The even better news for home-proud people who like their home to have the right look as well as the best function is that thermal curtains come in a variety of styles.

You can find thermal curtains in different sizes to fit most windows, and they can be bought in an array of vibrant colors to suit current décor or interior themes.

Where to Use Thermal Curtains

There are no hard and fast rules about where you should or should not place thermal curtains in your home.

In reality, you can place them wherever you prefer and need them the most.

Here are some popular places that buyers choose to place their thermal curtains and the reasons why:

  1. Living room – this is where you spend the most time at home and is where they will benefit you the most in terms of optimum temperatures and cutting energy bills.
  2. Children’s nurseries – the noise-reducing properties of thermal curtains enable you to keep young children sleeping, which means more sleep for you too!
  3. TV or gaming areas – the sun’s glare can often disrupt the entertainment from your latest binge-watching sessions or video gaming quests. Using them in the places where there are screens can help you stay focused and enjoy the action.
  4. Bedrooms – as the aforementioned examples explained, using them in a bedroom can help you sleep in on those well-deserved days off.
  5. Entrances – some people also place curtains in front of their entrances because doors are also a common way for heat to escape the home. This is popular in some restaurants during the winter months but there is no reason why you cannot do the same in your own abode.

So, Do Thermal Curtains Really Work?


All these benefits sound great, but do thermal curtains really work?

The answer is yes, but you need to buy thermal curtains using the best designs with tested technologies. This means spending a little bit more on the curtains to get a quality product. Thankfully, thermal curtains aren’t that expensive so you won’t need to break the bank.

You should also make sure your expectations are in check. Thermal curtains will certainly help reduce the energy bills, but they are not going to cut them in half.

They are a smart investment to make a small saving each month. If you are not noticing a difference, it may be possible that you have a bigger issue such as gaps between window panes due to faulty hinges or the need for some window maintenance.

Do not use thermal curtains as a way to cover up any bigger underlying issues with your windows or doors.
