Curtains can help keep heat in by acting as a barrier between the inside and outside temperatures. When curtains are closed, they create a layer of insulation that reduces heat transfer through windows. This can help to retain warmth inside a room and prevent cold air from entering. In fact, studies have shown that properly insulated curtains can reduce heat loss by up to 40%.
How curtains insulate windows
Contents
Curtains serve as a protective barrier, limiting the interchange of air between a chilly window and the surrounding room. They can significantly decrease heat loss, by approximately 40%, especially when they are designed to be floor-length and positioned close to both the wall and the window glass.
High-grade curtains excel in conserving warmth within the house, therefore acting as an efficient insulator against cold windows. Their capacity to hold heat is a practical method of ensuring indoor temperature stability.
Thermal Insulation Properties of Curtains
Curtains, through their thermal insulation properties, serve as an effective method to retain heat within a room, thereby enhancing a home’s energy efficiency. The inherent design and fabric of these fixtures form a barrier that decreases heat loss, with the air between the curtain and the window functioning as an insulator.
This mechanism prevents the warm air from seeping out and deters cold air from infiltrating. The insulation efficacy is notably amplified when the curtains are thermal or blackout types, which come with a specially designed lining to boost their insulating potential. Thus, during chilly weather, such curtains significantly augment the room’s heat retention capacity, leading to a reduction in energy expenses and promoting a more comfortable living ambiance.
Types of Energy Efficient Curtains
Known as thermal or insulated curtains, energy-efficient curtains are specially designed to minimize energy costs by retaining heat and blocking various forms of energy. In colder months, they prevent thermal energy from escaping through windows, maintaining a warm, comfortable indoor environment and reducing the need for excessive heating, which results in lower energy bills.
These curtains are often constructed from heavier materials like velvet, suede, or thermal-lined fabric, layered with a vapor barrier and a reflective film that reflects heat back into the room. Thus, the thermal energy generated by your heating system is conserved within your living space, significantly enhancing energy efficiency.
Benefits of Thermal Curtains
Thermal curtains, with their aesthetic appeal and practical design, make an excellent addition to any home aiming for a comfortable and steady indoor temperature. Their unique structure, typically constructed from heavier materials and incorporating multiple layers such as a foam core and a reflective surface, works to insulate windows.
They are particularly efficient during the colder months, as they are designed to retain heat within a room, preventing the intrusion of cold air and the escape of warm air. This ability not only provides a cosy atmosphere but also contributes to significant energy cost savings by reducing the need for excessive heating. Therefore, thermal curtains are a practical and effective solution for maintaining a comfortable indoor climate and managing high energy bills.
Curtain Material and Heat Retention
The material of a curtain plays a crucial role in maintaining a room’s temperature, particularly in terms of heat retention. Materials that are heavy and dense, such as velvet, suede, or tweed, are excellent insulators against cold temperatures. They form a physical barrier between the cold window and the room’s interior, trapping air inside and reducing the amount of heat that can escape through the window.
Contrarily, lighter, thinner materials like cotton or polyester are not as effective in preventing heat loss due to their ability to allow more heat to pass through. To optimize heat conservation, thermal or insulated curtains are recommended. These are designed with a special foam backing that adds an extra layer of protection against heat loss, further enhancing the curtain’s ability to keep heat within the room.
Insulating Window Treatments
Insulating window treatments, notably curtains, are crucial in heat retention within a room, particularly during colder periods. The material of the curtain, especially if it’s heavier or thermally lined, creates an insulating barrier that traps air between the fabric and the window, reducing heat escape and maintaining a steady room temperature.
Curtains also block the intrusion of cold air from the window, amplifying their insulating properties. These characteristics not only foster a warm and comfortable environment but also decrease energy expenses by minimizing the demand for extensive heating.
Effect of Curtains on Room Temperature
Curtains contribute significantly to room temperature regulation, acting as a thermal barrier between external conditions and the indoor environment, particularly through heat retention. When closed, the curtain fabric creates an insulating air layer between itself and the window, preventing the warm air inside from escaping, thereby maintaining a warmer room atmosphere.
The insulating effect is further augmented in thermal or insulated curtains, which feature a foam backing or a dense fabric layer. Consequently, curtains aid in maintaining a stable room temperature, promoting comfort and potentially reducing energy expenses by minimizing heat loss.
Heat Loss Prevention with Curtains
Curtains, particularly thermal or blackout types, are instrumental in maintaining a comfortable indoor temperature during cold weather by preventing heat loss. They achieve this through insulation, a principle that blocks conductive heat transfer between the indoor and outdoor environment.
Their fabric provides an extra insulation layer, slowing down the rate of heat escape through windows, typically the least insulated parts of a building. By trapping warm air inside and preventing it from leaking out through the window panes, curtains can effectively reduce the burden on heating systems and contribute to energy conservation.
Blackout Curtains and Thermal Insulation
Blackout curtains, made from a special material called thermal insulation, are known for their superior heat retention ability. This quality allows these curtains to block heat transfer, creating a barrier that prevents the intermingling of indoor and outdoor temperatures.
In the winter, they effectively trap indoor warmth, stopping it from escaping through the windows and warding off the cold outside air. Conversely, in the summer, they prevent outdoor heat from entering, keeping the room cool. This unique dual functionality of thermal insulation makes blackout curtains an energy-efficient means of maintaining a consistent room temperature all year round.
Draft Reduction with Curtains
Curtains, in addition to their aesthetic appeal, play a significant role in enhancing the energy efficiency of a home by preventing heat loss. They achieve this by curbing drafts, which are caused when cold air seeps through windows and doors, leading to a colder room and a consequent increase in energy usage for heating.
By serving as a protective barrier between the cold window or door and the room, curtains inhibit the intrusion of cold air and the escape of warm air. Their effectiveness in reducing drafts is directly proportional to their thickness. Furthermore, the manner in which curtains are hung can also affect their performance. Curtains that are hung to extend well beyond the window frame and close to the floor are more adept at keeping drafts at bay, thus ensuring a warm and cozy room.
How to Choose Insulating Curtains
Insulating curtains offer a stylish and practical solution to maintaining the temperature in your home, designed with a special thermal lining to trap heat, acting as an additional barrier against the cold from the windows. The thick material of this lining prevents heat from escaping through the glass, significantly reducing the need for artificial heating during colder months, which can lead to potential energy savings.
When choosing insulating curtains, it’s critical to consider factors such as material thickness, thermal properties, and the curtain’s ability to block out cold air drafts, as these will ultimately affect their effectiveness in keeping your home warm.
Does Keeping Curtains Closed To Keep Heat In?
By keeping the curtains closed and lowering the blinds, you enhance the barrier, which helps to reduce radiant heat loss. Also, keeping the curtains closed reduces drought and adds insulation.
Curtains feature-heavy clothing materials that are poor conductors of heat. Besides, when you close the curtains, you make it difficult for the cold air close to the window to mix with the warm air moving around in the room.
So, it allows the cold air between the window and the curtains to remain cold and keep the room’s warm air.
Insulated curtains are the best during winter. They make it difficult for air to escape, and so they help to retain warm air in the home.
But to get the best results, you ensure that the curtains you use have high finite resistance. Also, it would be best if you fixed them close to the window to reduce the loss of heat because of convection.
When you forget to close the curtain, the cool air outside the window makes the air around the window get cold.
Therefore, when the temperature outside the window drops, the air between the window and the curtain is likely to get cold, but it will not have time to mix with the warm air in the room.
So, by closing the curtains, you stop the air around the window from mixing with that in the room. This way, it helps to reduce heat loss and lowers bills.
Do Energy Saving Curtains Really Work?

Energy-saving curtains work quite well in regulating temperatures. They reduce the amount of heat the house gains during the winter by reflecting solar radiation.
It means that your AC will not need to work hard to lower temperatures in the home.
Note that homes without curtains lose 30 percent of heat to the environment. So, by installing the energy-saving curtains, you improve energy efficiency, which further helps to reduce the use of fuel. It greatly lowers utility bills.
Energy-efficient curtains will therefore work in two ways.
They reduce the solar gain in summer by 33% while reducing heat loss during winter by 25%. They are energy efficient, and if installed properly, they maximize energy-saving benefits.
Most of the curtains feature many layers of materials that offer thermal resistance.
The R-value determines how it prevents conductivity and transmittance. Therefore, curtains may come in two- or four-layer drapes.
They have a decorative fabric with densely woven materials that include linen, polyester, silk, wool, and cotton. The middle layer may feature foam, flannel, cotton batting, and other thermally resistant materials.
They may also feature a backing, which is another layer that acts as a lining and protects the curtain layers from sunlight.
Typically, the backing is light-colored to help to reflect heat and light. This is critical in summer since it reduces heat gain. The backing will serve as a vapor barrier which further helps to reduce solar gain during summer.
Thus, the best backing should be made of vinyl, reflective film, or cotton.
In some other cases, the curtain may feature a fourth layer that acts as a vapor barrier and further helps the curtains to save more energy.
Typically, energy-saving curtains work by creating air spaces between the room and the windows. It helps to reduce air infiltration and heat transfer.
When you install an insulating curtain, it keeps the heat inside during winter while reflecting the heat outside during summer.
But when you make the seal tight, you reduce the heat that escapes through the window but forces it to circulate within the room.
How Do Curtains Stop Heat Loss?
Curtains form a barrier between the window and the room. It makes it difficult for air to escape through the less resistant window as it seeks a cooler temperature.
Also, curtains make it difficult for the warmer air to escape through the cracks in the window seal. It, therefore, creates a barrier between the warmer air in the room and the cold air around the window. It stops heat loss and helps to reduce power bills.
Typically, curtains feature thick fabrics that make it difficult for light to penetrate. So, they reduce heat loss between the window and the room.
It stops the air from escaping through the least resistant path. So, by hanging the curtains in front of the window, you introduce a defensive layer between the two.
It helps to cut heat loss and keep the house warm. It saves money and reduces bills.
Which Curtains Are Best For Keeping The Heat In?

The best curtains to keep the heat in should be heavy and tightly woven. They should provide a barrier to make it difficult for air inside the room to mix with cold air between the curtain and the window.
But not all materials will prevent cold air from getting into the interior spaces; linen, sheer cotton, and lace may not be the best during winter.
So, it would help if you chose heavyweight curtains made of suede, denim, tweed, tapestry, and velvet.
These are the best materials that will provide a barrier against chill air, finding their way into the house through window openings.
Fabrics like canvas and cotton offer limited protection and so may not give you the best protection in winter.
Consider buying insulated curtains designed to block cold air from seeping into the home.
Those that feature four layers that include a high-density foam could be the best option for you. They prevent heated air from mixing with the cold air between the window and the curtain.
If they have a reflective film layer that deflects the heat back into the room, they could help to keep the room warm.
Best Curtains To Keep Out Cold
