This is honestly great, as everyone should work towards creating a better world. While there are impactful decisions such as recycling, upcycling, and focusing on energy efficiency with tech, sometimes, all you need to do is take a step back and see what small changes can be made. For instance, curtains, especially thermal curtains can be one of the best and highly recommended forms of energy efficiency.

It’s not impossible either to retain heat in your home, in fact, it can be very cheap and it can heavily reduce your energy bills too.

This is where insulated curtains come in, whether your home if operated by electricity, gas, or even an old fashion fireplace, this can all still add up to cost money.

doors and windows while also trapping in the curtain heat.

You can count on this to be a massive game changer, especially during the colder months or in areas such as the Northern US where it’s considerably colder all year round. Plus, some come in so many layers, even up to 4 layers to keep the cold out! So, why not reduce your carbon footprint today by investing in insulated curtains?

Do thermal curtains work in the summer?

Yes, thermal curtains can work in the summer months. Just as it’s important to work towards having a sustainable home during winter, you can do the same in the summer months too. So, even in the hot months, thermal drapes can be wonderful for reducing the air that escapes. Heat comes in through the crevices of windows, leaving the house hot, and the cold air escapes through those crevices too.

Plus, you need to keep in mind, that when the sun hits the window, that’s going to provide additional heat to the space, meaning that your air conditioner is going to have to stay on for a lot longer. But using thermal curtains and even insulated door curtain, you’re essentially blocking out the sun while blocking any unnecessary hot air from coming in. So yes, these are excellent in the summer, just as they are in the winter.

What type of lining is best for thermal curtains?

While windows are going to play a major role in controlling the temperature in your room, you’re also going to have to keep in mind that the curtains you choose are also going to make an impact. While it’s great to consult a buyer’s guide to learn about thermal curtains, sometimes all you need are the basics like the lining. More specifically, the type of lining that you choose is going to have an impact as well. So, here are some things you’re going to want to keep in mind when you’re looking into the right type of lining for your thermal drapes.

Thermal lining

You might be wondering what’s the difference between thermal and lined curtains, after all, these can make an impact. When it comes to sound insulating curtains lining, the thermal lining is going to consist of one layer (known as one pass) that’s coated with acrylic suede. This is going to increase the energy savings by helping the room stay warm. So, why is this important?

Well, it’s important to understand the construction of the fabric itself. You’re most likely going to want some light to pass into the room from the curtains, right? The heaviness is going to count, also, you’re going to have to be aware that you’ll need to clean the curtains too. A lot of fabric, curtains included tend to collect dust, and this along can be annoying. Some types of lining can increase the dust on curtains.

Blockout lining

While there is thermal lining for insulated drapes, there is also blockout lining. There are different varieties when it comes to blackout lining, so if you’re wanting to make a sustainable option, it’s best to get yourself familiar in order to decide if this is a good option.

Coated acrylic suede

Known as three-pass due to it’s three-layers of coated acrylic suede, the triple fabric is meant to retain more heat while also blocking out more light. This is different than thermal lining, as this allows some light to come in, three pass doesn’t allow for it. However, there are some similarities to thermal lining such as easily able to collect dust.

Plus, the silicone-coated lining is supposed to be very good for blocking out the sun too. Since it’s very this, it has the ability to retain heat much better compared to thermal lining. Thermal window coverings with silicone-coat can be a great option. However, unlike acrylic suede lining, this doesn’t going to hold onto any dust. Instead, it can be easily cleaned by wiping it down with a damp cloth.

Dimout weave

The dimout weave, also known as the “triple weave” is a lining that consists of a woven construction rather than just a coating. This means that is has a thicker feel to it while still being softer. Since this is weaved, it does mean that some small amounts of light and easily pass through. This is considered one of the more energy-efficient choices compared to the thermal lining.

How Can You Ensure That Your Curtains Last a Long time?

When it comes to sustainability, it’s not just about the curtain you choose but how you take care of it.
