Typically, they made with a core layer of high-density foam that protects the windows from sound and heat exchanges, a layer of reflective film for reflective the heat back into the room, and a vapor barrier that doesn’t allow the foam to absorb moisture. The outer layer of decorative fabric is what counts the most for the appearance of the curtains.

Q: Can insulated curtains help you save energy?

A: A house with air conditioning or central heating will benefit from the insulated curtains since they don’t allow air to enter/leave the room. During winter, insulated curtains will maintain the heat inside, reducing the heat you need in the home. Once summer kicks in, insulated curtains will not let cold air escape from the room, so you don’t need to use the air conditioning anymore.

Q: Should you get insulated curtains or energy-efficient windows?

A: Energy-efficient windows save energy since they prevent heat transfer. The big downside is the price, as this type of window can be costly. On the other hand, the insulated curtains cut down your utility bill and are affordable. They’re stylish and can change the appearance of any room.

Q: Are there many styles of insulated curtains?

A: There are all types of insulated curtains, such as hobbled shades, Roman shades, classic curtains, and side-draw shaded. You may integrate them into draperies, shutters, valances, and all kinds of systems. The outer layer of the insulated curtains can be of any style and type so that you may customize the appearance and feel of insulated curtains for any room in your home.

Q: What size should the insulated curtain be?

A: The size of the insulated curtain is related to the size of the window and the looks you want. The rule of thumb is that you need to measure the distance between the floor and the ceiling for obtaining the proper length. 63in, 84in, 95in, 108 in, and 120in are the standard lengths for insulated curtains.

If you’d like a traditional appearance, the curtain should hang 6in above the top of your window frame, 3 in beyond the sides, and 3in below the bottom of the frame. Hanging the curtains so that the bottom rests 1 in from the floor will give you a modern vibe. The width of the curtains should be up to three times wider than the window. If you’re aiming for a luxurious appearance, you need to hang the curtains close to the ceiling. The bottom needs to rest on the floor, creating the “puddled” feel.

Q: Thin or thick fabrics?

A: Sheer fabrics are excellent for allowing natural light, but you need thick materials if you’re aiming for insulation. There are numerous options to choose from, and thick material ensures better insulating properties for the curtains.

Velvet, cotton, polyester, microfiber, and silk are common choices for insulated curtains. It all depends on the décor and the looks you’re trying to create. Insulated curtains come in a nice variety of patterns, sizes, and styles as they’re not only functional but also aesthetically pleasing.

Q: Can you install insulated curtains in any room?

A: You should use insulated curtains in rooms with the most exposure to natural sunlight.

The thick material will also block the outside noise, so make sure you get the most adhesive fabric for rooms with continuous exposure to loud sounds. If you’re planning to install insulated curtains in the bathroom, the material should be water-resistant so that it takes humidity and doesn’t grow mold.

Q: Is the liner necessary when using insulated curtains?

A: There are different liners to install, allowing you to have the best curtains for your rooms. A thermal liner is the best option for getting the best out of your insulated curtains. For instance, you can use a thermal liner for blocking the hot and cold air escaping through an ample space in the case of sliding door draperies. A blackout liner for blocking the light will be a dependable option for a bedroom or nursery, whereas a flannel-backed liner is excellent for a living room.

If you’re using insulated curtains in your bedroom, you should also get a water repellent liner to keep moisture away.

Q: What’s the know about cleaning and keeping the insulated curtains in good shape?

A: Maintaining and cleaning insulated curtains can be a challenge, and you should always begin with the instructions from the manufacturer. For maintenance, you should open the curtains so that moisture doesn’t build up, generating mildew. It’s essential when you live in a humid climate with heavy winter precipitation.

When it comes to cleaning, you can spray the curtains with some spray-on upholstery cleaner and vacuum afterward. You can also have the curtains dry cleaned, but the processes shouldn’t be immersive.

Q: Can you improve the efficiency of your insulated curtains?

A: Even if insulated curtains give great results on their own, you can always do more for the best results. For obtaining maximum energy saving, you can layer cellular shades with your insulated curtains. Cellular shades are made with honeycomb-shaped cells that collect heat and chill. Layering the shades with curtains will ensure better insulation.

Q: Is there a difference between insulated and blackout curtains?

A: Blackout curtains are made with tightly woven fabric for keeping sunlight away from getting inside. Most of the time, the blackout curtains present a thin liner inside for blocking sunlight efficiently. They make an excellent addition to any room with too much sunlight, such as a living room or bedroom.

Insulated curtains are made with a layer of acrylic foam between the double/triple layers of fabric, ensuring insulation. They’re efficient in the winter, but can also dampen sound and block sunlight, lowering our utility bills. Both insulated and blackout curtains have insulating and blackout abilities, but it’s only the insulated models that are made explicitly for protecting a room.
