Do Blackout Curtains Keep Cold Out?

In winter, homes become cold because of heat loss through the doors and windows. Cold air let in through gaps and heat escapes, making your home feel cold. Proper insulation is required if you want to maintain the indoor temperature. Blackout curtains act as an insulating barrier between the room and the outside atmosphere. They help reduce airflow of cold air through their dense fabric and reduce heat flow through the insulation. If you are the one looking for the answer to this query, do blackout curtains keep the cold out? This blog post will give you the answer in detail.

What Are Blackout Curtains?

Blackout Curtains Dubai are crafted from heavy, dense fabric. These are multi-layered fabrics usually lined with a foam or acrylic layer to block the light. They come in tightly woven polyester, cotton, or blends of these materials and are good for bedrooms, studios, and nurseries for efficient light control.

Blackout curtains differ from regular, thermal, and soundproof curtains depending on their layers, intensity of controlling light & insulation. Regular curtains are made from single-layer fabric that can diminish the intensity of light to some extent. It filters the light, not completely blocking it. Whereas blackout drapes are lined and efficiently block light.

The main difference between these heavy-fabric curtains in Dubai and thermal drapes is their efficiency in controlling light and insulation. Thermal curtains are also made from dense fabric but lined with a special thermal lining that reduces heat transfer in and out of the interior. These are more energy efficient and focus more on insulation.

Do Blackout Curtains Really Keep Cold Out?

Yes, blackout window curtains really keep the cold out in winter. Primarily, cold air enters through the window glass, the gaps around the window frame or sides, and the poor sealing around the windowpanes.

The thick, tightly woven fabric does not naturally allow air to pass through it. Whereas in multilayer construction, air is trapped between the thermal lining of the drapes and the windowpane, which later on acts as a barrier against the heat transfer. It reduces the flow of cold air into the room and prevents the escape of hot air from the inner side.

For air gaps and heat loss prevention, you need to seal all the gaps around your windows. Make sure the curtains are properly installed, covering the window entirely for maximum light blockage. Hanging a wider and longer curtain can help you keep the cold out.

Hence, these blackouts are best for the space where you want to create complete darkness and some energy efficiency. It can reduce your energy bills by up to 20%. But for hot climates, where the energy cost is higher to keep your homes warm in winter, blackout drapes with thermal lining are ideal. Along with efficient light control, they provide better energy efficiency than the normal blackout window treatments. They also reduce noise and give you a calm and peaceful space.

How Blackout Curtains Help Insulate Your Home

To understand their insulating properties, we will discuss several aspects. This will explain the process of insulating your home with blackout curtains.

1. Thick Fabric Creates a Thermal Barrier

Due to their multi-layer construction, they act as a barrier and reduce the transfer of cold air and heat transfer. Keeping the cold air out and hot air in will reduce airflow near windows &

Regulate your home temperature.

2. Blocking Drafts Around Windows

Thick drapes also block the drafts around the windows and make the interior comfortable. If there are still cracks or gaps around the window seals, cold air leaks through them and makes the air next to the window glass cold. As the cold air becomes heavy, it moves downward and causes a draft, which is disturbing and increases the energy cost.

To resolve the drafting issue, make sure the windows are fully covered. Thick curtains act as a solid barrier against cold drafts near windows.

3. Reducing Heat Loss at Night

In winter, these drapes will trap warm air inside and block the cold air from entering. This happens mainly because trapped air is between the cold window glass and your lined curtains. This barrier acts as a buffer zone that reduces the effect of drafts and reduces the energy cost by heating the room. During colder months, your thick and dense window treatments will help you reduce heat loss at night and give you energy-saving benefits (less load on your heater and lower energy bills).

How to Use Blackout Curtains to Keep Cold Out Effectively

After you have a clear idea of how blackout curtains work and where they can be installed for extra benefits. Here are some expert ideas you must consider before hanging these drapes to keep the cold out effectively.

Choose the Right Size and Length

• Measure the curtain length and width accurately to ensure proper curtain size.
• Proper-sized curtains give full coverage, which blocks light and heat
• Select the proper-length curtains according to your desired look
• Floor-length curtains work best in blocking the warm air from escaping
• The extra width of your drapes is ideal for better insulation, as it leaves no room for air leaks & gaps.

Install Curtains Properly

• Hanging curtains higher and wider than the window will give maximum light blockage and insulation.
• Place the rods at the right-aligned position for full coverage
• Use wraparound rods to reduce gaps

Layer Blackout Curtains with Sheers or Liners

• Choose the layering option for added insulation through windows
• Use double curtain rods, which are sturdy and should be wider than your window frame (6-12 inches on each side).
• Layering blackout curtains with blinds or shades will give the best results
• Using cellular shades on the outer side of the window and blackout on the inner side will enhance the insulation

Best Rooms to Use Blackout Curtains for Cold Protection

For cold protection, while choosing blackout home curtains, consider the purpose of your room. Every space has different insulation needs. You can install the thick velvet curtains in bedrooms to create complete darkness for improved sleep. For living room curtains, you can go for layering blackouts with sheer drapes for a comfortable and stylish interior. You can close both layers for insulation and open the blackout for filtering light during the day.

For nurseries and media rooms, our soundproof curtains with thick lining are also energy efficient. They provide insulation by maintaining privacy and darkness for a restful environment.

Home offices also need protection from cold so that the employees can work in a comfortable environment with high productivity.

Common Myths About Blackout Curtains and Cold Weather

Blackout drapes reduce heat loss in winter by providing insulation. But they are not 100 % efficient. There are some myths regarding blackouts and cold weather. Let’s discuss a few to understand well.

The first myth is: “Blackout curtains completely stop cold air.” But the reality is different. They help reduce heat loss unless you have the specialised thermal-insulated curtains. The second myth is “They replace proper insulation.”

People might confuse these curtains with dedicated thermal curtains. Their primary function is to block light. These do not properly insulate the space unless they are lined with thick thermal lining. This lining absorbs the air that lies between the room and the window. These still air pockets serve as an insulating layer, which reduces the flow of heat and cold.

Additional Ways to Keep Cold Out Along with Blackout Curtains

To keep the cold out efficiently with your regular blackout curtains, you need to follow these steps.

• Apply sealing around window frames (Weatherstripping windows)
• Using thermal liners
• Closing curtains at night and opening them during the day

Conclusion

At the end of this blog, we can say that blackout curtains are good for insulating your room in winter. They keep the cold out and lower energy bills by reducing heating costs. To enjoy all the benefits, you must install them properly with the proper length and width. Floor-length curtains with fullness provide full coverage & are the best insulators. Layer them with other curtains or blinds for better warmth and energy efficiency.
