Blackout Shades vs Room Darkening Shades

Looking for new window treatments? You may have already encountered two terms that are used in the window covering industry: blackout shades and room-darkening shades.

On the surface, they may appear to be the same, but they’re different.

Knowing the differences between blackout and room-darkening shades may help you best choose for your particular household needs.

Be it trying to reduce screen glare while watching your favorite show, improving sleep quality by minimizing light, enhancing privacy, or simply knowing the options available, understanding the offerings of each is imperative.

In this complete guide, we will provide you with insights on the key differences between blackout and room shades, their pros and cons, ideal use cases of each, and help in making a decision which is best for you.  

What Are Blackout Shades?

Blackout shades are one of the most effective window coverings available in the market that block 100% of outside light from entering a room. It is designed to eliminate the light entering windows and enhance window privacy.

As blackout shades fully close windows, they can create total darkness at any point of the day. This is possible due to the use of opaque materials and tight-sealing designs that ensure no light can seep in.

These shades are perfect for:

• Individuals who rest during the day (shift workers)
• Parents with infants or toddlers
• Homeowners 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.

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.)

Their purpose is not to block light completely but to offer a balance between privacy and brightness.

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.

These shades become even more versatile and flexible, boasting an increased range of patterns, colors, textures, and fabrics.

Key Differences Between Blackout and Room Darkening Shades

Let’s simplify it:

Common Materials Used In Each Type  

The amount of light that comes in is dependent on the kind of material used:

Blackout Shades Materials

• 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

• 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.

Comparison of Light Control

This is how they do it for light control:

1. Blackout Shades: Block all light. Best during the nyctophilia hours, great for shift workers and media lovers, especially during the night. Helps those sensitive to even a sliver of brightness.

2. Room Darkening Shades: Best when you want a peaceful but calm room. Dim natural light without fully blocking and maintaining the user's ability to see around the room without activating lamps.

Most shades are predicted to have customizable light with smart app adjustable settings based on the time of day.

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.

Room Darkening Shades: Better for mild climates, helps regulate temperature but not as effectively. Rooms that don’t face direct sun are better for these shades.

Privacy Levels: Which Option Works Better?

During the night, with lights on, privacy is essential.

• Blackout Shades: Prevent all visibility from outside. 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.

Thus, 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 disturbance.
• Nurseries: Assists babies in napping during the daytime, even when it’s bright outside.
• Home Theaters: Eliminates glare and reflections on the screen.
• Guest Rooms: Provide a hotel-style experience and ensure comfort during the stay.

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.
