Blackout Shades vs Room Darkening Shades

Trying to choose between blackout shades and room darkening shades for your new room? The Brignox team is here to help. 

The key difference between room darkening shades and blackout shades is that room darkening shades block about 95% of the light coming into a room, whereas blackout shades block 99%-100% of light. So, one makes your room very dark while the other makes it pitch black.

What’s the better choice for you? It depends on what you’re after. 

We recommend blackout shades for when you need total darkness, like in your bedroom or in a nursery. 

Room darkening shades are fine for bedrooms and nurseries, too. But they’re more common in living rooms, dining rooms, or home offices. 

If you still need help deciding, we recommend that you keep reading this article. In this guide, we’ll cover everything you need to know to make a sound decision. Including:

• What these shades are
• How they work
• The pros and cons of each
• And some feature comparisons

What Are Blackout Shades?

Blackout shades are window coverings designed to block out nearly all light from entering a room. That’s why they’re called blackout shades. Think of it like a “movie theater” effect.

They're built with dense, tightly woven fabrics or materials that prevent sunlight from passing through, which is why they're so effective at blocking light even during the brightest times of day.

They’re so effective that if someone were to shine a flashlight or even their car’s headlights into your room, blackout shades would block the light. 

What makes them different from regular curtains or blinds is that they’re built with multiple fabric layers or a foam backing that acts as a light barrier. 

If you’re looking for curtains for a bedroom or nursery, blackout curtains are the answer.

You’ll be happy to know that they also help with insulation. They keep your rooms cooler in summer and warmer in winter since they prevent heat transfer through windows. We highly recommend them if you want better sleep or just need the perfect movie-watching environment.

These shades are perfect for:

• Individuals who rest during the day (shift workers)
• Parents with infants or toddlers
• Homeowners who want a theater-like movie room
• People who live in noisy neighborhoods or near streetlights

Nowadays, blackout shades are more advanced than ever. Most models include motorized lifting and app integration.

Did You Know? There are many types of blackout window treatments (products designed to completely block incoming light). Other types include room-darkening curtains, blinds, and shutters.

What Are Room Darkening Shades?  

Room darkening shades allow soft, diffused light to filter through while reducing light significantly more than standard shades. (Click here to know more.)

They don't create complete darkness, but they still do create a darker environment.

You don’t get that same “opaque” feeling as you do in a movie theater, but it still makes the room very dark and drastically reduces glare.

These light-filtering shades still let in around 5%-15% of light, which is great when you’re socializing or gathering as a family. Nobody wants to eat together in total darkness, right?

Oh, and they’re also usually cheaper than blackout shades.

Still can’t decide? Here’s a rule of thumb: is it a room for sleeping? Get blackouts. Is it a common room? Get room darkening shades.

These shades are best for:

• You want to reduce natural light without achieving total blackout.
• You want spaces that are dimmed yet naturally illuminated.
• You need a sense of privacy without feeling boxed in.

Key Differences Between Blackout and Room Darkening Shades

The major differences between blackout and room darkening shades are the amount of light they let through, their ideal use case, materials, and costs. 

The following table contains all of the key differences between these two types of shades in greater detail: 

Common Materials Used In Each Type  

The most common materials for blackout shades are triple-weave, vinyl, or polyester, whereas room darkening shades are typically made from cotton blends. But there’s a lot of variation and nuance here. And the material can actually affect the price and performance of your curtains.

Blackout Shades Materials

The number one difference in the room darkening vs. blackout shades battle is the material that they're made from. Blackout products (including blackout blinds) are made from blackout fabric, usually polyester. These thicker materials prevent light completely from entering your room and result in energy savings (more on that below).

• Often three-layer fabric with vinyl or foam backing
• Dense polyester or acrylic blends
• Layers that block UV rays
• Heat-reflective coating

These materials work to capture light and outside noise while also blocking heat.

Room Darkening Shades Materials

These shades are made from room-darkening fabrics, synthetic materials, or a mix of both. Common room darkening materials include:

• Woven polyester or cotton blends
• Mid-opacity fabric
• Layered sheer overlays

These materials work to create an even, softer glow that enhances the warmth of daylight, transforming a room into a relaxing and inviting space.

Blackout Shades vs. Room Darkening Shades: Key Features Comparison

Comparison of Light Control

Blackout shades are hands down better for light control. They block out 99-100% of light and create near-total darkness even in the middle of the day. 

Room darkening shades only filter out about 85-95% of light, which means you'll still see some brightness coming through, especially from strong sunlight or streetlights. If you need complete darkness for sleep, shift work, or blocking out headlights and street lights, blackout shades are the only real option. You can close this article and go get them now!

Energy Efficiency: Which One Saves More?

There is a clear winner when it comes to choosing energy-efficient window shades. 

Blackout Shades provide superior energy efficiency due to dense material that traps heat in winter and reflects sunlight in summer. With these, heating and cooling systems have less work to do (and your bills go way down).

Room Darkening Shades don’t provide the same level of temperature control. We recommend them for mild climates. They definitely do help regulate temperature, just not as effectively. 

While we are here, we want to recommend a few other options that might be helpful for you. Have you heard of honeycomb shades or sheer shades?

Honeycomb shades have cellular pockets that trap air, creating insulation that reduces heat transfer through windows, lowering heating and cooling costs. Sheer shades feature translucent fabric layers that filter sunlight while maintaining views, reducing solar heat gain and glare without blocking natural light, which minimizes air conditioning needs while keeping rooms naturally bright.

Privacy Levels: Which Option Works Better?

Once again, blackout shades provide better privacy since they block out all the light. If you’re a celebrity hiding from the paparazzi, we recommend getting blackout shades. Room darkening shades will still let some light through, which means someone could still technically see in if they really, really wanted to.

Here’s a bit more of a breakdown.

• Blackout Shades: Prevent all visibility from outside. We are talking absolute darkness here. No light in, no light gaps, no light seepage. No nothing. Regardless of whether a bright lamp is on, no one is able to see inside. Most suitable for bathrooms and bedrooms.
• Room Darkening Shades: Provide moderate privacy during the daytime. However, if there are interior lights during the night, shapes and shadows may be visible from outside.

For complete privacy, blackout is the better choice out of the two options.

Best Rooms for Blackout Shades

These are the rooms where blackout shades are most beneficial:

• Bedrooms: Ensures restful sleep without being disturbed by outdoor lights. The enhanced privacy is a bonus, too.
• Nurseries: Assists babies and small children in napping during the daytime, even when it’s bright outside. This is one of the unique advantages that makes these products so special among our customers.
• Home Theaters: Eliminates glare and reflections on the screen. This is that movie theater effect we were talking about.
• Guest Rooms: Provide a hotel-style experience and ensure comfort during the stay.

Long story short, anywhere light control and privacy matter most, get blackouts.

Best Areas for Room Darkening Shades

Common areas that don’t need full illumination reduction benefit most from room darkening shades. Some of the best rooms are:

• Living Rooms: Reduces glare on TV but preserves natural light.
• Dining Rooms: Enhance ambience and foster an inviting space.
• Kitchens: Decrease excess heat and UV damage while allowing daylight in.
• Home Offices: Maintain focus while blocking harsh sunlight.

Anywhere you want some light but not too much…that’s where you should get room-darkeners.

Best Areas for Room Darkening Shades

Common areas where full illumination reduction is not needed are best suited with room darkening shades:

• Living Rooms: Reduces glare on TV but preserves natural light.
• Dining Rooms: Enhance ambience and foster an inviting space.
• Kitchens: Decrease excess heat and UV damage while allowing daylight in.
• Home Offices: Maintain focus while blocking harsh sunlight.

This is the optimal balance—light, but not too much.

How Do You Install Blackout or Room-Darkening Shades?

Both types of shades have two methods of installation. Read more to know how to install blinds & shades.

1. Inside Mount: This mounts inside the window frame, which looks clean and tidy. It works fine for room-darkening shades, but if you're using blackout shades, you'll probably get some light sneaking in around the edges where the shade doesn't quite reach the frame.

2. Outside Mount: This mounts above and outside the window frame, so the shade covers more area. It's the better choice for blackout shades because it eliminates gaps where light can sneak through. If you really want total darkness, go with an outside mount for your blackout shades, or pair inside mount shades with curtains to cover those edge gaps.

Blackout Shades vs Room Darkening Shades: Pros & Cons

Before you go, we promised you some pros and cons of blackout and room darkening shades. Here they are all spelled out in a table:

Blackout or Room Darkening? How to Decide

If you’re still unclear, we want to give you some tips on how to decide. Our team put together this buying guide to give you a hand. See which category you fit in and choose the right type of curtain based on our suggestion:  

Choose blackout shades if:

• You need complete darkness and total privacy
• Light from outside is messing with your sleep
• You want better insulation to save on heating and cooling costs

Choose room darkening shades if:

• You like some natural light filtering through, but want to reduce glare
• You prefer keeping the room bright and open during the day
• You just need to dim things down without going full blackout

Your daily routine, sleep patterns, and the primary function of the room should determine your selection.

Expert Tips on Choosing The Right Curtains

Picking the right shade isn't always black and white. Sometimes you need a mix of both, depending on the room. Our team wants to leave you with some helpful tips before you go.

Here are some practical ways to get the best setup for your home.

• Mix and Match: Use blackout shades in bedrooms where you sleep and room darkening in living rooms or kitchens where you still want some natural light.
• Use Dual Shades: Some shades let you switch between light filtering and full blackout modes, so you get both options in one setup.
• Add Curtains: Layer blackout shades with curtains for extra light blocking and a more polished look that also adds insulation.
• Go Smart: Automated shades with timers let you control light levels without getting up, which is great for consistency and convenience.
• Check Direction: If your windows face east or west and get blasted with harsh morning or afternoon sun, blackout shades will save you from the glare and heat.

Conclusion: The Best Choice for You

Thanks for reading all the way through. In the end, it's pretty simple. Blackout products like shades or blackout curtains totally block light, which creates the perfect atmosphere for watching movies or watching TV. They're also great for privacy and energy savings.

Room darkening shades (and room darkening blinds) let in less light, but they cost less, and they're great for rooms where light control matters less, and you want more light (such as family rooms).

You just need to decide whether you need 100% privacy or 80% privacy. Once you do, let us know. We can help you with getting custom window treatments, custom shades, or anything else you might need.
