Having a room that is filled with natural light is great, but sometimes too much light can be a bit of a headache. Whether you’re trying to enjoy a movie or get a good night’s sleep, too much light can be a distraction and leave you feeling frustrated. That’s why knowing how to blackout windows can be a fantastic way to solve this problem.

We’ve broken down this article into three main sections to make it easy for you to follow. The first section will cover the basics of blocking out light from windows, the second section will give you 12 specific steps to follow for achieving optimum darkness, and the third section will provide you with some tips and tricks for maintaining your newly blacked-out windows.

So without further ado, let’s get started!

Section 1: The Basics of Blocking Out Light from Windows

1. Understanding Light

Before we dive into the steps for blocking out light, it’s important to understand how light behaves. Light can pass through or reflect off of various surfaces, including glass. This means that even when curtains or blinds are closed, light can still make its way into a room. Understanding this principle lets us begin to think about ways to prevent excess light from entering our spaces.

2. The Purpose of Blackout Curtains and Shades

One way to stop light from entering a room is through the use of blackout curtains or shades. Blackout curtains are made from thick, opaque fabric that blocks out light, while shades are made from materials such as vinyl or PVC, which are designed to prevent light from passing through.

3. Blinds and Curtains: What’s the Difference?

Blinds and curtains both serve the purpose of adding privacy to a room, but they differ in how much light they block. Blinds are more adjustable, allowing for different levels of light to be let in, while curtains tend to be more opaque. To achieve optimal darkness, it’s recommended to use blackout curtains or shades to supplement your blinds if your goal is to block out as much light as possible.

Section 2: 12 Steps for Achieving Optimum Darkness

Step 1: Measure Your Windows

The first step in the process of blocking out light is to measure your windows to determine the size of curtains or shades you need. Be sure to measure the width and length of your windows accurately.

Step 2: Choose the Right Curtains or Shades

Once you have your measurements, it’s time to choose the right curtains or shades for your windows. Blackout curtains or shades are the most effective for blocking out light, so it’s recommended to use these rather than regular curtains or shades.

Step 3: Install Curtain Rods or Tracks

Now that you have your curtains or shades, you’ll need to install curtain rods or tracks. This will allow you to hang your curtains or shades and adjust them as needed.

Step 4: Attach Curtains or Shades to the Rods or Tracks

Once your curtain rods or tracks are in place, it’s time to attach your curtains or shades to them. Make sure they are properly aligned and secure.

Step 5: Use Velcro Sheets to Block Light

One way to block out excess light is to use Velcro sheets on the top and sides of your curtains or shades. This will help ensure that no light can enter through gaps or areas where the curtains or shades don’t cover.

Step 6: Add a Valance or Top Treatment

In addition to blocking out light, adding a valance or top treatment to your curtains or shades can also help enhance their appearance. This can be a great way to tie your room together and add some personality.

Step 7: Install Shades Inside the Window Frame

If you’re unable to install curtains, another option is to install shades inside the window frame. This can be a great alternative to curtains and can be just as effective at blocking out light.

Step 8: Seal Any Cracks or Gaps Along the Window Sill

To prevent light from coming in from the bottom of the window, be sure to seal any gaps or cracks along the window sill. You can use weather stripping or caulk to do this.

Step 9: Install Window Film

Window film is a great way to block out light and add some privacy to your windows. It’s easy to install, and it can be a great way to achieve the darkness you desire without having to add curtains or shades.

Step 10: Install Shutters

Another option for blocking out light is to install shutters. They can be a great way to block out light and add some aesthetic value to your home.

Step 11: Add Bookshelves or Other Furniture Against Windows

If you have bookshelves or other furniture that can be placed against windows, this can be a great way to block out excess light. Be sure to choose furniture that is sturdy and will not block out too much light.

Step 12: Add Draft Stoppers

Finally, adding draft stoppers to your windows can be a great way to block out excess light. They can also help regulate the temperature in your room, making it even more comfortable.

Section 3: Tips and Tricks

1. Use a Sleep Mask

If you’re still having trouble sleeping, even with your newly blacked-out windows, consider using a sleep mask. This can be an effective way to block out any remaining light and ensure a good night’s sleep.

2. Choose Light-Blocking Colors

Choosing light-blocking colors for your curtains or shades can be a great way to enhance their effectiveness. Darker colors are more effective at blocking out light than lighter ones.

3. Draw Curtains or Shades Earlier in the Evening

Drawing your curtains or shades earlier in the evening can be a great way to allow your body to adjust to the darkness. This can help you fall asleep more easily and wake up feeling more refreshed.

4. Keep Your Room Cool

Keeping your room cool can be another way to ensure a good night’s sleep. This can be achieved by opening windows during the day to allow fresh air to circulate and using fans to cool down your space.

5. Use Double- or Triple-Layered Curtains

If you’re still having trouble blocking out light, consider using double- or triple-layered curtains. This will add an extra layer of insulation and increase the curtains’ effectiveness at blocking out light.

6. Use Dimmer Switches for Overhead Lights

If you have overhead lights in your room, consider installing dimmer switches. This will allow you to adjust the amount of light to your desired level.

7. Use Hangers to Prevent Wrinkles

To ensure that your blackout curtains or shades remain effective, be sure to use hangers to prevent wrinkles. This will help maintain their shape and effectiveness.

8. Keep Your Curtains or Shades Clean

To maintain the effectiveness of your curtains or shades, be sure to keep them clean. Dust and debris can accumulate on them, reducing their ability to block out light.

9. Consider the Environment

When choosing curtains or shades, it’s important to consider the environment you’re in. For example, if you live in a noisy area, choosing thicker curtains can help block out sound as well as light.

10. Experiment with Different Methods

Finally, don’t be afraid to experiment with different methods for blocking out light. Everyone’s preferences are different and what works for one person may not work for another. Try out different combinations of curtains, shades, and window films to find what works best for you.

We hope this article has provided you with some useful tips on how to blackout windows. With the right techniques and a little experimentation, you can create a space that’s both comfortable and private, giving you the restful sleep or focused relaxation you need. Happy blackout!
