Blinds vs Curtains for Warmth

Blinds vs Curtains for Warmth

When it comes to maintaining warmth in your home, the choice of window dressing plays a pivotal role. Two popular options are blinds and curtains, each with its own set of advantages and characteristics. This article aims to explore the efficacy of both blinds and curtains in retaining heat, helping you make an informed decision for your home. 

From aspects such as the material and design, to the installation and maintenance, we will delve into how these factors can affect the thermal efficiency of your home.


Blinds can be a highly effective tool for insulating your home, especially when they are accurately measured and installed. The way they work is by capturing a layer of air between the fabric of the blind and the window. This trapped air creates an effective seal over the window, preventing the escape of warm air. 

To maximize this benefit, it’s best to raise the blinds during the day. This allows sunlight to enter and naturally warm the interior of the house. As the sun goes down, lower the blinds. This will then retain the warm air generated by the sunlight and any mechanical heaters, keeping the house comfortable throughout the night.


Curtains also have a role to play in home insulation. Their effectiveness largely hinges on their weight and thickness. Heavier curtains help prevent heat transfer between the cold air surrounding the windows and the warm air in the room. Generally speaking, the thicker the curtains, the more powerful they are at insulating. 

The most efficient insulating curtains feature a lining on the back that boosts their insulation properties without impeding airflow or noise transfer. For optimal effect, consider adding a second pair of curtains behind the first; special curtains are available that are specifically designed for this insulating purpose.

Comparative Analysis

According to research findings from the University of Salford, curtains can make a significant difference in retaining heat within the home. Drawing the curtains at dusk can lead to a decrease in heat loss of 15-17%. 

Blinds, while less efficient, still contribute to minimizing heat loss, with a decrease of 13-14%. Although the difference might seem minor, it is significant, and justifies the practice of closing blinds or curtains during colder months to conserve heat. This comparison further underlines the importance of window coverings in preserving energy and enhancing comfort within homes.

Which one is better

In conclusion, both blinds and curtains have unique advantages when it comes to insulating your home. Your final choice between the two may ultimately come down to preference and the aesthetic of your interior decor. 

However, it’s noteworthy to mention that if your home features older or drafty windows, upgrading to new, insulating windows can dramatically augment the warmth and energy efficiency of your home. In instances where significant heat loss occurs through windows, blinds can offer a cost-effective solution, saving you valuable dollars on your electricity bill. Thus, whether it’s blinds or curtains, each has a substantial role to play in maintaining a cozy and energy-efficient home.
