Understanding Blackout Shades

Room Darkening Shades vs Blackout Shades
While homeowners often use the terms interchangeably, room darkening shades and blackout shades are not exactly the same. Room darkening window treatments significantly reduce incoming light while still allowing some visibility within the room. Blackout shades are designed to block up to 99% of incoming light, creating the darkest environment possible.
The results depend on several factors, including fabric opacity, the type of window treatment selected, window depth, installation method, and potential light gaps around the edges. For bedrooms, nurseries, media rooms, and shift workers who sleep during the day, blackout shades often provide the highest level of light control.
Many homeowners choose room darkening shades when they want increased privacy and glare reduction without completely darkening the space.

How to Reduce Light Gaps
Light gaps are the small slivers of light that can appear around the edges of window treatments. Even with blackout fabrics, these gaps may allow light to enter the room, reducing the overall darkening effect.
Light gaps are often caused by shallow window frames, outside-mounted shades, or the natural design of certain window treatment styles. Homeowners who are sensitive to light may notice these gaps most often in bedrooms, nurseries, and media rooms.
Fortunately, there are solutions. Hunter Douglas offers the exclusive LightLock™ system, available with select Duette® Honeycomb Shades. This innovative U-shaped channel helps seal out light at the window frame for one of the darkest blackout experiences available.
Another effective option is layering custom drapery panels alongside blackout shades. This combination helps reduce light gaps while adding softness, style, and additional light control to the room.

Dual Shades for Daytime Light & Nighttime Darkness
The Dual Shades system offers one of the widest ranges of light control available. Instead of choosing between light filtering shades and blackout shades, homeowners can enjoy both in a single window treatment.
A front sheer shade softly filters natural light, preserves the view, and helps reduce daytime glare. When additional privacy or darkness is needed, a secondary blackout roller shade lowers into place behind it.
This innovative design is ideal for bedrooms, living rooms, and media spaces where lighting needs change throughout the day. Many homeowners pair blackout roller shades with Silhouette® Window Shadings or other light filtering fabrics to enjoy beautiful daylight, enhanced privacy, and room darkening control—all on a single headrail.

Room Darkening & Blackout Shade FAQs
Are room darkening shades the same as blackout shades?
No. Room darkening shades significantly reduce incoming light, while blackout shades are designed to block the highest level of light possible. The final result depends on fabric opacity, window size, mounting style, and light gaps around the edges.
What shades block the most light?
Blackout cellular shades with side channels offer some of the strongest light-blocking performance. Hunter Douglas Duette® Honeycomb Shades with LightLock™ are designed to help seal light at the window frame for a darker room.
How do I eliminate light gaps around blackout shades?
Light gaps can be reduced with the right product, precise measuring, and professional installation. Options like LightLock™ side channels or layered blackout drapery can help block light along the edges of the window.
Are blackout shades good for bedrooms?
Yes. Blackout shades are an excellent choice for bedrooms because they help block early morning sunlight, streetlights, and exterior light at night. They are especially helpful for nurseries, guest rooms, and shift workers who sleep during the day.
Can blackout shades be motorized?
Yes. Many blackout and room darkening shades can be motorized for easy control with a remote, smartphone app, or voice command. Motorized blackout shades can also be scheduled to close automatically for bedtime, naps, or movie nights.
