Do Sheer Curtains Block The Sun? (Explained)

Sheer curtains are lightweight curtains, made of thin fabrics that fall and drape over windows beautifully. They have an airy and billowy structure that adds warmth, softness, and elegance to a room.

Sheer curtains look nice on their own, but they also work as a second layer of curtains. They look good when layered with thick curtains to add more depth and dimension to your room.

Sheer curtains do not block the sun, but they can diffuse natural light coming from the sun.

Here is how sheer curtains work with the sun:

Sheer curtains do not block out light coming from the sun. However, they can act as a diffuser or a filter. They work by softening the light that comes from the sun so that the glare is reduced. They can also block out harmful UV rays to reduce the risk of sun damage and fading.

Do Sheer Curtains Soften Natural Light?

Even though sheer curtains do not block light from the sun, sheer curtains are still nice to have as they can soften the natural light.

They add an airy vibe to a room, and can even make an illusion of a larger and more spacious room.

Sheer curtains are usually made of thin and lightweight fabrics that are translucent and loosely woven. They normally come in white or in soft colors and are almost see-through. These curtains are designed to filter light and soften it as it enters the room.

Sheer curtains tend to give a room soft natural lighting instead of harsh glaring lights.

Soft natural lighting is good for relaxing spaces like lounges and bedrooms.

Are Sheer Curtains Good for Sleeping?

If you want to have good sleep, then sheer curtains are not the best option for window coverings.

Compared to regular opaque curtains and blackout curtains, sheer curtains are not effective for making a room dark.

If you work the night shifts and you want to get good quality sleep during the day, sheer curtains will not work for this. Because they let light in, sheer curtains can even prevent you from falling asleep during the day.

When it is nighttime, sheer curtains can still let in ambient light coming from outside. If the streets are lit or if you have outdoor lights, sheer curtains can let a small amount of light in.

While the light coming in is not that distracting because it is still relatively dark outside, sheer curtains cannot be used if you really want a blackout effect in your room.

If you want curtains that are good for sleeping, then your best option would be dark opaque curtains or blackout curtains.

These curtains can effectively block light from entering the room to make it dark.

Dark curtains and blackout curtains can significantly darken your room so you fall asleep faster.

They can also help improve the quality of your sleep by reducing the noise coming from the outside and letting you sleep longer with fewer interruptions.

Are Sheer Curtains Bad for Privacy?

Sheer curtains can be good or bad for privacy, depending on what time of the day it is.

During the day, sheer curtains are actually good for privacy. Even though they are translucent and somewhat see-through, they can still provide a good amount of privacy indoors.

Sheer curtains may not be able to block light from entering, but they can definitely prevent outsiders from being able to see the inside of your house.

When it is nighttime, sheer curtains are a bad idea.

If you have sheer curtains and the lights inside the house are turned on, people from the outside can see what is going on inside the house.

Sheer curtains do not provide any privacy at night.

This is why it is a good idea to layer sheer curtains with thicker curtains. You can have the best of both worlds as the sheer curtains work nicely during the day to allow warm light and good air circulation indoors.

Then when it is dark, you can close the thicker curtains over the sheer curtains so you get the privacy that you need at night.

Can Sheer Curtains Be Made Thicker?

Sheer curtains are often made from fabrics like polyester, linen, cotton, rayon, gauze, and a lot more. These fabrics are normally made to be thin, which is what makes them great for sheer curtains.

Sheer curtains are normally thin so essentially, they cannot be made thicker.

The fibers used are normally spun thin and there is no way to make these fibers denser.

However, if you want more privacy but do not want thick fabric curtains, you can always double your sheer curtains by simply taking another one and placing it over the other.

Doubling the sheer curtains will add privacy, while still letting diffused natural light in your room.

What Kind of Curtains Do Block Sunlight?

If you want curtains that block sunlight, then here are some options that you can consider.

Blackout Curtains

Blackout curtains are window coverings that are made of tightly-woven fabric with multiple linings.

These curtains are thicker than most curtains, and they are made t0 block all light from entering. Blackout curtains can make a room completely dark.

The only way that light can get it is if there are gaps between the curtains and the edges of your window.

You can prevent this by consulting a professional and by taking the exact measurements of your window before buying the blackout curtains.

This is to make sure that the blackout curtains fit your windows perfectly.

For maximum darkness, you can also layer your blackout curtains with more curtains.

Generally, blackout curtains are the best choice if you want your room to be as dark as possible. Out of all other types of curtains, they also provide the most privacy.

Helping Your Sleeping Cycle

Blackout curtains can help the length and quality of your sleep by blocking all light and even reducing background noise coming from the outside.

In fact, blackout curtains make you more sleepy.

These curtains are great insulators so they can also make your house more energy-efficient and they can significantly reduce your utility bills. They can even reduce your electricity bill by up to 25%.

When the weather is warm, blackout curtains can help keep the room cool by blocking warm air from entering.

And during chilly months, these curtains block cold air to keep the room warm.

Blackout curtains are great for bedrooms, home theaters, nurseries, lounge rooms, or any room that can be used for relaxing or napping in the middle of the day.

Dark Curtains

Just like blackout curtains, dark curtains are made to block light from entering. These curtains are made of an opaque fabric in dark colors, and they usually have a lining attached to the fabric. Dark curtains are not as heavy as blackout curtains in terms of fabric density.

Dark curtains are also more affordable.

However, since dark curtains are not as thick as blackout curtains, they still allow a small amount of light to enter and pass through the fibers.

While dark curtains are effective in making a room significantly dark, they cannot provide the maximum darkness that blackout curtains do.

Additionally, dark curtains provide a good amount of privacy both during daytime and nighttime. When it is nighttime and the lights are on, dark curtains prevent people from being able to see through the inside of the house.

Just like blackout curtains, dark curtains can also help you sleep better since they can darken a room to an extent. They can help soften any background noise coming from outside the room.

They can also help reduce utility bills as they are also good insulators.

If you want curtains that can block enough light to create a cozy atmosphere and improve your sleep, then dark curtains are a good option. They do the job of significantly darkening the room, without it becoming completely dark.

Plus they only cost a fraction of the price of blackout curtains.

To summarize sheer curtains are beautiful and elegant, but they do not block light.

If you have sheer curtains and you want a darkening effect in some areas of the house, it is best to buy dark curtains or blackout curtains to layer with the existing sheer curtains.
