Blackout curtains have the added feature of having the blackout property built into the cloth, making for a heavier cloth with less light-blocking properties. But they’re still lighter than other fabrics and look much like normal drapes. In other words, they don’t have the layered look that cloth curtains do, where different layers give different blocking effects. However, in blackout curtains, this is done through a thin layer of blackout fabric, layered very close to the surface of the cloth.
A lot of blackout curtains still use open-faced, flat-screen fabric materials. These are popular because of their light-blocking abilities, as well as their ability to be fairly easily cleaned. This means that the curtain doesn’t have to be vacuumed. The material is vacuumed, though, using a low-vibration fan. It’s also important to make sure that it has been treated to keep it from being damaged by light – a treatment that helps make it last longer.
Because of the nature of blackout curtains, the design is often decorative. Some are very elaborate, incorporating some sort of pattern or texture, and even having zippers at the top to help you open them. Other curtains are designed like regular, thick drapes (there’s no special “zipper” design), but because the fabric is opaque and has this” blackout property,” the top is usually made of a very thick, solid, natural light-blocking fabric with no fringe.
Now, one might ask why, if this curtain is supposed to be used to keep sunlight out of a room. The answer is that polyester is a very good insulator. And a blackout curtain made of polyester fabric (even a light colored one) has the effect of keeping out both heat and cold. Polyester is so tightly woven that it can’t be easily punctured. Therefore, it is an excellent room darkening curtain and one that will keep your home cooler in the summer and warmer in the winter.
Another possible complaint is that some people find it hard to get blackout curtains to stay closed, especially when their windows are located near the middle of the room. The key to this is that they are designed to close in a uniform manner, as if they were one solid panel. So, if you have one small window facing the other, and if you want the drapes to stay closed, all you have to do is take one step down the rows, lay the curtains on top of each other, and then stand back and wait for them to close. You should have no problem doing this, depending on the thickness of the fabric and the window frame you’re trying to block out.
Finally, another frequent complaint about blackout curtains is that they are not very easy to clean. As with most other window coverings, there are a variety of cleaning solutions available, ranging from a simple cloth swab to professional truck mount cleaning equipment. But, if you don’t want to deal with cleaning them at all, or you have pets that like to go inside the house, or if you live in a very humid area, you may find that blackout curtains are not very practical, at least when compared with other, more durable options like blinds. But if you need something very durable that will stand up to time and heavy use, blackout curtains may just be the right choice for you.
