What Are Thermal Blackout Curtains?

Thermal blackout curtains are particular types of curtains used for insulation and blocking out natural lighting. Although you can buy thermal curtains and blackout curtains separately, finding a curtain that combines the two is much better. They feature layers of extra fabrics, which perform different roles.

There’s a decorative layer that adds to your home’s aesthetics. These layers are made out of cotton, wool, silk, polyester, or other decorative material. The second layer consists of materials resistant to heat, such as acrylic foam, which is also heavily woven to block out light.

The third layer acts as a lining that reflects sun rays. This outer layer facing the window can also act as a barrier for protecting other layers from moisture. This outer layer features reflective materials, such as vinyl. Some thermal blackout curtains also feature a fourth layer.

Do Thermal Blackout Curtains Work?

Thermal blackout curtains work well in all seasons. During winter, they provide a barrier limiting the level of cold penetrating your house. During summer, the outer layer provides a reflective effect, bouncing the sun rays to the outside and limiting heat gain.

In addition, the curtains will create a hollow space between the window and your home’s interior, reducing air infiltration.

To achieve the blackout effect, Manufacturers insert the heavily woven fabric. You also have the freedom to make your curtains as dark as possible, depending on the number of layers. The primary function of thermal blackout curtains is to provide thermal resistance and prevent conductivity.

Things to Consider When Selecting Thermal Blackout Curtains

Thermal blackout curtains feature three or more layers of fabric; decorative, the foam core, and the vapor barrier. Although these layers are crucial, you still must consider several factors, such as fabric, type, and aesthetic. Here’s a detailed list of things you should consider before purchasing these curtains.

1. Size

Like all other curtains, thermal blackout curtains come in different sizes. However, for the best results, find curtains that cover the entire window casing. Generally, thermal blackout curtains come in various lengths, including 63 inches, 84 inches, 95 inches, 108 inches, and 120 inches.

The curtains can also hang from the leaving an allowance of 1 inch to 6 inches, depending on the desired look. Additionally, remember to leave at least a 3-inch space on both sides.

The same applies from the distance from the ceiling; the closer the rod is to the ceiling, the better your curtains will look. Of course, if you’re unsure of the measurements, you can always consult a professional for more information.

2. Fabric

Like traditional curtains, the fabric used to design thermal blackout curtains is essential. The materials come in various types, such as cotton, silk, polyester, wool, or microfiber. But selecting the suitable fabric depends on your home décor and personal taste.

Typically, the best fabric for thermal blackout curtains is either polyester or microfiber. Polyester doesn’t absorb moisture, and the microfiber is the best in creating a blackout effect. You can also combine polyester and cotton to make the curtains heavier.

3. Insulation

Your thermal blackout curtain should have an internal insulating layer made out of acrylic foam or a thick cotton batting. All insulating materials have R-values that can determine the curtain’s insulating value. Generally, the higher the R-value, the better the insulating value. Most thermal curtains will have an R-6 value, which reduces heat loss/gain significantly.

4. Aesthetic

What Color Should Blackout Curtains Be

Thermal curtains can also be stylish, adding to the aesthetics of your home. Therefore, don’t settle for less. Find thermal curtains that complement your home décor and uplift every room’s appearance. It’s easier to make a perfect choice while selecting the fabric. You can choose an appropriate color or pattern for the outer layer that’s facing your room.

5. Maintenance

Thermal blackout curtains are not the same. The cleaning process can be as simple as using a washing machine or as demanding as taking your curtains to the dry cleaners. For efficient maintenance, it is better to abide by the manufacturer’s instructions.

However, you can open the curtains to allow air circulation and reduce moisture accumulation. Alternatively, you can use a vacuum and spray-on cleaner to keep the curtains clean.

In conclusion, thermal blackout curtains are an excellent investment. They work by saving energy and being cost-effective in the long run. Make sure you conduct your due diligence and seek professional help if you’re unsure of your selection. Stay warm.
