How Do Curtains Keep Heat In

When it gets cold, you are likely to resort to heating the house to keep it warm. Doing so often is expensive and is likely to increase your energy bills.

Therefore, you may need to review your priorities to ensure that you do not lose most of the heat to the environment through the windows.

Of course, there are many approaches you can use to reduce the amount of heat the house losses through the windows.

But installing appropriate window curtains is cheap and is likely to give you the desired results.

Curtains keep the heat in by limiting the amount of air between the outside and inner parts of a house.  Heavy curtains form a barrier that reduces airflow from the room to the space between the curtain and window. It reduces heat loss and keeps the room warm.

Curtains reduce the amount of airflow between the cold and the warm room.

Thus, using a set of heavy curtains will form an excellent barrier that limits the amount of air that flows from the room through the window.

Of course, some particles will flow and move through the gaps, but you are likely to get better results if you hang the curtains well.

Continue reading to get a clear picture of how curtains keep the heat in.

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.

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.

The curtains should allow you to retain your privacy and enable you to view what is happening outside through the window.

Thus, sheer curtains keep the heat in, but you will need to add another layer of protection to keep the outside cooler temperature at bay. 

If you can buy the right size and know-how to install them, it could help to keep the heat in.
