3. Go For Curtain Liners

Going for blackout curtain liners is a great way to blackout your window and get that extra amount of sleep that you need. If you already have a curtain that does not have a blackout feature, then you can easily head over to a store to purchase a blackout liner and fix it to the curtain.

The main aim of this solution is to utilize thick fabrics to prevent the penetration of too much light from the outside. This means that you will not be needing surfaces that are dark in color as long as you have the liners.

You can take things up a notch and purchase a thermal liner as they come with several benefits. Firstly, they can either warm up or cool down your room depending on the season. What’s more, is that it helps reduce your energy consumption.

4. Use Roller Shutters

Roller shutters are very effective when it comes to controlling the light in your room and they can create a very dark environment. These shutters not only give your room protection from the sunlight, but they are also efficient against low temperatures and noise.

If you are also looking for a way to shut out prying eyes, then you can’t go wrong with roller shutters. They come in a variety of shapes and sizes and you can make your selection for any window in your home. Ensure you call in a professional to help with the installation of these structures.

The blackout window tint film is a type of decorative window film that is great at totally blocking light coming into your room. While other decorative films would restrict how well people see through your window, that is not the case with a window tint film.

These window tint films come in various shades and possess a gradation in light transmittance. You can attach the tint film to your window from either the inside or outside, whichever suits you best. If possible, you should get a professional to attach it to your window as it would be difficult to notice if placed properly.

Window tint films cover your whole window pane and have been found to be excellent in blocking the rays of the sun.

6. Use A Mesh Liner

If you are looking for a cheap and affordable solution for blacking out a window, you should probably consider getting a mesh liner. It provides appropriate airflow to the room it is installed in even if it doesn’t offer a 100% blackout feature.

While the mesh liner is a semi-blackout material, you can incorporate it in between blackout window covers to get the best out of it. If you want to set the mesh liner, first measure the dimensions of the window, and then cut it accordingly, ensuring that it is the perfect fit for your window.

If you are looking to make it a permanent solution, you can utilize it as an extra curtain by using the hooks to attach it.

7. Get Blackout Curtains

Another very effective way to blackout windows is using a blackout fabric or curtain. Typically, you will find a curtain in practically every room in a house with a few exceptions. If you are looking to stop the penetration of sunlight into your room, you don’t need to look too far.

Getting a thick curtain with multiple layers will help you in achieving your goal of blacking out your window. If you don’t want to add blackout liners to your current curtains, then you will need to purchase the full blackout curtains that are made from a polyester-cotton combo.

While traditional curtains have their benefits, they are not as effective in blocking out light as blackout curtains. What’s more, blackout curtains regulate temperature, insulate your room, and also soundproof your house.

8. Install Blackout Shades or Blinds

If you are not a fan of those traditional heavy curtains maybe because they can collect dust, make your room smaller, or other reasons, then you can go for a more lightweight option in the form of blackout blinds or shades.

Window blinds are a very popular solution for blacking out a window and they also tend to improve the interior of the room they are installed in. Also, this solution is not one that is too challenging to install. There are a couple of advantages to using window blinds or shades to blackout your window.

These blackout shades come with a tight weave that is great for blocking out both UV rays and artificial light with ease. They also meet modern aesthetic requirements and are very durable.

9. Install A Window Awning

If you are constantly getting disturbed by light penetrating your room, you can opt for a beautiful architectural solution that shuts out the light from the outside. Installing a window awning is a long-term solution that helps to blackout your window, particularly if you still want your window exposed.

Even if your room is facing the sun as it rises, you can reduce the glare with awnings. What’s more, is that this solution works very well if the sunlight is getting into your room through a particular angle. Since the awning is placed outside the room, you don’t have to worry about it changing the interior of your room.

A window awning has great tensile strength, long service life, and high density, and it also protects your window from rain damage.


There are multiple reasons why you might want to black out your windows. The sunlight that passes through your window surely comes with its benefits and advantages, but it can become a nuisance, especially when you are trying to get that all-important rest.

With the steps we have provided in this guide, you can easily blackout your window without making your room pitch black. Every option listed here is an effective window blackout solution, so make your selection of window coverings according to your personal preference and budget.
