If you’re looking for a way to keep the light out of your room, reduce outside noise and ensure privacy, block-out curtains are just what you need. These curtains are designed to block out sunlight and offer an extra layer of insulation. This makes them perfect for bedrooms, media rooms, and other spaces where you want to control light levels.

Picking out the right block-out curtains and blinds can be a little confusing, though, especially if you’ve never shopped for them before. You need to consider the material, style, color, and length, as they can all impact the effectiveness and aesthetics of your curtains.

In this guide, we’ll explore everything you need to know about block-out curtains, including how they work and what to look for when shopping. 

What are Block-out Curtains?

Block-out curtains, also known as blackout curtains, are thick, heavy curtains made from a special fabric designed to block out light. The fabric is often made from thick, tightly woven polyester, cotton, or velvet. It has an acrylic or foam backing that helps insulate the room and prevent heat loss in the winter or heat gain in the summer.

Block-out curtains are ideal for those who are sensitive to light and noise, as they create a dark and peaceful environment that is perfect for sleeping or relaxing. They are also popular among shift workers who work at night and want to sleep during the day. The curtains typically come in various colors, patterns, and styles, so you can choose a design that matches your home décor and personal preferences.

Choosing the Right Block-out Curtains

When choosing the right block-out curtains for your needs, there are a few things you should consider. 

Here are some factors to keep in mind as you shop:

  1. Light-blocking capacity

The primary job of block-out curtains and blinds is to block out light. When shopping for block-out curtains, you must ensure that they have enough opacity to prevent light from penetrating them. 

It’s important to note that not all block-out curtains are created equal. Some may allow small amounts of light to filter through, and some may block out all light completely. The effectiveness of block-out curtains in blocking the light will depend on the type of fabric used and the thickness of the lining used to construct the curtains.

  1. Material

Block-out curtains are often made from thick, tightly woven fabrics like polyester, cotton, silk, or velvet. While cotton and silk are popular choices, polyester is often the best option for block-out curtains because it’s more durable, easy to clean, and less likely to fade.

You should consider not only the functional properties of the fabric but also its aesthetic qualities. The fabric’s texture and color can significantly impact the overall look and feel of the room. For example, velvet block-out curtains are a perfect choice if you are looking for a more formal or luxurious look. Cotton or polyester may be more suitable if you prefer a more casual and relaxed look.

  1. Size

The size of the curtains is also an important consideration, especially if you want complete light protection. The size can impact the curtain’s effectiveness in blocking out light, regulating temperature, and reducing noise. For instance, curtains that are too short may allow light to filter through at the bottom, while curtains that are too long may bunch up on the floor and create a tripping hazard. That’s why it is essential to measure your windows carefully to ensure the curtains you select are the correct size. The general rule of thumb is to choose curtains at least two times the window’s width and hang them so that they touch the floor.

  1. Style and design

Block-out curtains come in various styles, including grommet, rod pocket, modern panels, and pinch pleat curtains, among others. Your style choice may depend on the overall look and feel of your room and your personal preferences. Opt for pinch pleat curtains and decorative hardware if you have a traditional or formal space. If your decor is more sleek and modern, choose simple, clean-lined panels or grommet curtains.

Also, the design of the curtains is another important consideration. Block-out curtains are available in a wide range of colors and patterns, allowing you to choose a design that complements the style of your room. Solid colors are a popular choice for block-out curtains because they provide a clean, modern look that complements various decor styles. Patterns and prints can add interest and texture to the room, but it is crucial to choose a design that does not overwhelm the space.

  1. Color

The color of your curtains can have a significant impact on your room’s ambiance. Darker colors such as black, navy, and maroon are more effective at blocking out light and adding a touch of elegance to your space, but they may make the room feel smaller or more closed off. If you select a dark color for your block-out curtains, it is important to balance the room with light-colored walls or other decor elements.

On the other hand, neutral colors, such as white, beige, and gray, provide a clean and modern look that complements most decor styles. These colors also reflect light, which can help regulate the room’s temperature, particularly in the summer.

Now let’s look at some of the block-out curtains available in the market.

  1. Soundproof curtains

These curtains are designed specifically to reduce noise levels, ideal for bedrooms facing busy streets or noisy neighborhoods. Soundproof curtains use special fabrics that act as a barrier against sound waves and prevent them from entering your home.

  1. Insulated curtains

Insulated curtains are ideal for homes that struggle to maintain a consistent temperature. They act like a layer of insulation and prevent warm air from escaping in the winter and cool air from escaping in the summer. This can help you reduce your power bills by reducing the reliance on heating and cooling systems.

  1. Room-darkening curtains

Room-darkening curtains are perfect for bedrooms, nurseries, or home theatres, as they block out natural light. These curtains provide a dark, cozy environment perfect for sleeping or watching movies during the day.

  1. Blackout curtains

Blackout curtains are an even thicker, denser version of room-darkening curtains. They offer the ultimate level of light-blocking capacity, perfect for shift workers or individuals with sleep difficulties. These curtains eliminate virtually all light from penetrating the curtain, making them the preferred choice for complete light control.


Block-out curtains are an excellent investment if you seek light and noise control in your home. By understanding the crucial factors to consider when selecting block-out curtains, you can make an informed decision that meets your needs. Whether you opt for room-darkening or insulated curtains, investing in high-quality materials that will last for years and provide the required level of functionality you require is essential.
