Blackout Shade Guide: Shedding Light on Sleep, Style and Function

Written By Armi Avila

In the world of window coverings, blackout blinds and shades are among the most requested by homeowners in the Greater Seattle and Bellevue areas. Also referred to as room darkening, light dimming, or opaque shades, their purpose is consistent: to block or significantly reduce incoming light. Beyond light control, these window treatments offer practical benefits, especially in the Seattle area where long summer days, privacy needs, and energy efficiency are top priorities.

In this guide, we’ll explore why blackout window treatments are growing in popularity throughout Greater Seattle, set realistic expectations, highlight their benefits, showcase top product options, and share design tips for anyone considering room-darkening solutions.

What Are Blackout Blinds?

Blackout blinds, or more accurately, room darkening window coverings are designed to significantly reduce or eliminate outside light from entering a space. The term "blackout" typically refers to the fabric's opacity level. These window coverings are perfect for rooms where light control is a priority.

Why Blackout Shades Are Gaining Popularity in Greater Seattle

While blackout window coverings have long been a solution for bedrooms and media rooms, demand has surged across the Seattle region due to several local factors.

1. Extended Summer Daylight Hours

Greater Seattle experiences long daylight hours during summer, with sunsets as late as 9:00 PM. While this is ideal for outdoor activities, it can make winding down or putting children to bed on schedule challenging. Blackout shades help create a nighttime atmosphere even during daylight hours.

2. More Windows and Increased Urban Density

Newer homes are often designed with larger or multiple windows to bring in natural light. At the same time, neighborhoods like Ballard, West Seattle, and Madison, along with suburbs such as Bellevue, Kirkland, and Mercer Island, have become denser, with homes built closer together. While privacy can often be addressed with light-filtering fabrics, many homeowners choose blackout shades when complete control over incoming light is top priority, and especially on windows facing the street or neighboring properties.

3. Focus on Energy Efficiency

Energy efficiency is a major priority for Seattle homeowners, especially in older homes or those with large or multiple windows. Blackout shades, particularly cellular or honeycomb styles, offer insulation benefits that help reduce energy loss in both summer and winter months.

4. Home Media Rooms and Remote Workspaces

With more people working from home and creating home entertainment spaces, glare control is essential. Blackout window treatments help reduce screen glare and create a more conducive environment for movie watching or video conferencing.

Why Total Blackout Isn't Always Possible

It's worth noting that while the actual blackout fabric is designed to block light entirely, achieving 100% darkness with operable window coverings is extremely difficult.

True blackout can be hard to accomplish unless a window is completely covered with a non-operable solid piece of wood. Since window coverings are designed to be operable for daily living, small gaps are typically present along the sides, bottom, or top of the treatment. Gaps often exist between the window frame and the shade largely due to functionality to operate and the way window coverings are constructed, which allow light to seep through. This “halo effect” is also more apparent due to the contrast between the light coming through and the actual room darkening material, compared to a light filtering fabric where light comes through.

Other factors affecting blackout effectiveness include:

• Window construction, squareness, and frame depth
• Number of windows in the room
• External light sources such as streetlights and security lights
• Room orientation (i.e. east-facing rooms get strong morning sun)
• Window size and shape limitations

Despite these challenges, proper product selection and expert installation can significantly improve room darkening.

Benefits of Blackout Window Coverings

Whether in Queen Anne, Bellevue, or Kirkland, blackout shades offer advantages far beyond light blocking:

1. Better Sleep Quality

Blackout blinds reduce disturbances from streetlights, passing cars, and early sunrises, helping kids, shift workers, and light-sensitive sleepers get better rest.

2. Improved Energy Efficiency and Insulation

Quality blackout treatments, especially Hunter Douglas Duette® Architella® honeycomb shades, provide an insulating layer, maintaining indoor temperatures by reducing heat loss in winter and blocking solar heat in summer, which lowers HVAC costs and increases comfort.

3. Enhanced Privacy and Security

Opaque coverings prevent outside visibility, providing peace of mind. They also obscure whether someone is home, subtly enhancing security.

4. Optimal Light and Glare Control

Ideal for media rooms, home theaters, and offices, blackout shades minimize glare, improving screen visibility and room functionality.

Top 3 Room-Darkening Products

Here are the best blackout blinds solutions to consider:

1. Honeycomb Shades (Cellular Shades)

Our most popular product, honeycomb shades are among the most effective options for room darkening because they tend to have a narrower gap on the sides compared to other shade products, which helps minimize light seepage. In addition, their cellular structure traps air in the combs, offering both insulation and energy efficiency.

Pro Tip: Considering upgrading and adding the LightLock® feature, a U-shaped side channel to further minimize light leakage and improve the blackout performance.

2. Roman Shades

Roman shades also offer narrow side gaps and a provide softer look compared to honeycomb shades. It is ideal for those seeking a classic aesthetic with effective light blocking.

3. Custom Drapery

When you have the ideal window or sliding glass door and wall configuration, a wall-to-wall, floor-to-ceiling blackout-lined drapery provides exceptional light control. Beyond blocking light, custom drapery add warmth, texture, and excellent for sound absorption.

Pro Tip: Mount drapery rods wider than the window to reduce light bleed from the sides and add visual width to the window.

Additional Functional & Design Considerations

To make the most of your blackout window coverings, here are some tips and considerations:

1. Top-Down/Bottom-Up Functionality

Maintain daytime privacy while letting in natural light from above by choosing honeycomb or roman shades with top-down/bottom-up feature. This gives you greater control over light and visibility, ideal for ground-level rooms or homes with close neighbors.

2. Layering Is Key

Combining blackout shades with decorative drapery panels blocks more light and adds texture and dimension, giving your space a polished, layered look.

3. Mounting Style

For better blackout, outside mount installation is an option, which extends beyond the window frame to reduce side gaps. However, weigh this against inside mount installations, which preserve the window frame integrity and often look more aesthetically pleasing than an outside mount application.

4. Automation

Motorized blackout shades enable convenient operation—program them to let in a bit of morning light when it’s time to wake up or close fully when it’s time to darken the room.

5. Preventing Moisture Buildup

It’s important to raise your room darkening shades occasionally to allow air circulation and prevent condensation or mold to form and to preserve longevity of your shades.
