Do Thermal Curtains Work Or Are They Just A Fad?


Curtains go a long way in creating the perfect ambience for the room. They are a time-tested solution to all the window covering issues. From sheer curtains to curtains with thick fabrics, they’ve shown a great impact on interior design through its functionality and visual appeal. Furthermore, thermal liners are added to extend its light filtering and insulation properties. Here, we will discuss the advantages of thermal curtains in a home.

What are Thermal Curtains?

Thermal curtains are crafted from several layers of materials that enable them to offer thermal resistance, also called R-value. This property makes the curtains capable of stopping thermal conductivity, also known as U- value. Typically, thermal blinds have three layers, although two and four layers are also available for customization. The inside layer is a decorative fabric made from woven cotton, polyester, linen, or silk- which helps create the desired ambience in the room. The middle layer comprises foam, flannel or any similar material that is thermally resistant. The third layer is the backmost fabric that protects the inner layer from direct exposure to sunlight. This last layer acts as a vapour barrier for the middle foam from condensed water droplets found around windows. If ordered as a lighter shade, this backing layer can reflect light and heat. Thus, it drastically reduces the buildup of heat in a room during the summer.

How does a thermal curtain work?

Thermal curtains create a buffer between the window and the room. The advantage of it is that the air infiltration through conductivity is reduced. In the summers, the buffer created by the thermal curtains does not allow the outside hot air to enter into the room and in winters, the escape of heated inside air is stalled. Furthermore, since the thermal curtains cover the window completely, they limit the heat that can escape in or out, thereby, efficiently maintaining air circulation within the room.

Do thermal curtains work or are they just a fad?

Thermal curtains have many advantages; hence they indeed work. They are currently in trend and will remain important because of the practical benefits they bring to the house. Following are some of the advantages of a thermal curtain:

  • Thermal Curtains Provide Comfort to the Owner:

Thermal curtains are designed so that they reduce the heat exchange from the window. So in summers, they do not allow the outside air to infiltrate the room, while in winters, they do not allow the old outside air to enter the room. As per a study, thermal curtains can reduce heat loss by up to 25 percent from windows. With less heat loss, it becomes easier to maintain a comfortable temperature in the room.

  • Thermal Curtains Reduce Electricity Bills:

The thermal curtains will reduce the heat exchange and infiltration from the room windows. Thus, be it summers or winters, the HVAC system won’t have to work round the clock to keep the room temperature uniform. This ultimately helps in the reduction of total electricity bill and is also a main reason why majority of the hotels use thick and heavy curtains. They are undoubtedly durable, but they help reduce heat loss; thereby, reducing the electricity bill.

  • Thermal Curtains Ensures Less Wear and Tear of the Heating System:

Thermal curtains ensure that the HVAC system does not have to work for a longer duration of time. It is because of the ability of the thermal curtains to provide great insulation. With less usage, the HVAC system collects less debris and faces less wear and tear. Clearly, with less load on the system, the overall lifespan gets increased.

  • Thermal Curtains Provide Effective Sound Insulation:

An additional benefit of having thermal curtains is that they successfully provide insulation to the room and dampen external noise. Thus, they help make the room noise proof and relax or do his work with total concentration. In addition to it, thermal curtains, because of their multiple layers, also go a long way in absorbing the internal noise. This is also why having them in music studios and home theatres is effective.

  • Thermal Curtains are Available in Different Colour Options:

There is a wide array to choose from when it comes to material, design, and color. Some of the most popular ones are cotton, microfiber, polyester and silk. Microfiber and polyester provide the best insulation. In addition, these are moisture-resistant and are not affected by the presence of water droplets created in the air. These droplets get trapped in between the window pane and the curtain.

  • Thermal Curtains Enhance the Aesthetic Appeal of the Room:

Gone are the days when people associated thermal curtains have sloppy shapes and ill-fitted fabric. These days, thermal curtains come in a wide variety of shades, styles, and colour combinations, allowing consumers to create the theme of his choice in the room. Traditional, modern, classical, or boho-chic themes are some that are available in the market, to name a few.

  • Thermal Curtains Successfully Block Sunlight:

Thermal curtains are very successful when it comes to blocking the sunlight from entering the room. They should not be confused with full blackout curtains as both maintain a line of demarcation, and one cannot be substituted by another. But in addition to providing sound insulation, they can create a near blackout effect in bedrooms. They are a must-have for those who live in hot areas or those who have to do night shifts.

  • Thermal Curtains Provide Absolute Privacy:

Thermal curtains do an excellent job of providing privacy to people. Being multi-layered, they create a safe space from the intruding gazes of passersby. Everyone needs a private space to relax and rejuvenate. Once the thermal curtains are drawn, privacy is created where no outside intrusion can affect his peace of mind.

Installation and the efficiency of the thermal curtains

To ensure the proper efficiency of insulating blinds or thermal curtains, they need to be installed properly. First, ensure that they are air-tight so they stop the transfer of heat more efficiently. These should be installed closest to the window frame, ensuring that they are adequately sealed. It has been observed that it can reduce the heat loss by 19 per cent with a proper seal around the window. A cornice or valance is a welcomed addition on top of a thermal curtain. Velcro, magnetic tape or any other adhesive can set the curtain on the window frame.  At the center, the curtains should be the thickest to avoid the escape of air. Thermal curtains have a lot of advantages. They make the room aesthetically appealing and provide good insulation along with sunlight control and privacy. Thermal curtains are certainly not a fad, and are here to stay.
