How does it fit to my window?
UBlockout shades can be mounted inside or outside of your window
Your mount type will depend on your style aesthetic, window space and obstructive features.
Outside Mount
The shade sits around the window opening.
Please note, Outside Mount has a maximum width and height of 96"
Will it fit outside my window?WILL IT FIT INSIDE my WINDOW?
You need at least 1" of free recess space
This is window space that is clear from obstructions.
What are obstructions?
Check for common obstructions
Some obstructions can stop a shade from fully closing or achieving 100% blackout and light filtering performance. These can be found anywhere inside the window opening, including the sides and on the window itself.

Inside Mount not right for you?
Go to Outside MountWILL IT FIT securely INSIDE THE WINDOW?
Your window needs to be as even as possible - not 'out of square'
We encourage you to take measurements for width and height from three different locations.
If any of those measurements of width or height vary by more than one quarter inch (1/4") your window may be out of square.
Your window being out of square may risk the ability to achieve 100% blackout.

Frequently asked questions
Where are the shades made?
Every UBlockout shade is handcrafted in Dallas, Texas, using premium materials and precision-engineered aluminum frames.
Our team assembles each shade with meticulous attention to detail, ensuring it meets the highest standards of quality, durability, and performance. From design to delivery, every step of the process reflects our commitment to creating the world's ultimate blackout shade — one that combines innovation, beauty, and craftsmanship in equal measure.
How are UBlockout shades different from any other blackout shade?
UBlockout shades are unique as they are they are DIY-friendly shades that can deliver 100% blackout. Our patented design and superior technology completely eliminates light leakage, unlike other standard shade solutions on the market.
What payment options can I use?
You are able to pay via Visa, Mastercard, American Express, Affirm and Afterpay. We also support HSA/FSA payments via Flex.
How can the UBlockout app and SmartHome integration help with our sleep?
The smart shade functionality can help you achieve better sleep in several ways:
Customization: With remote-controlled operation, you can precisely adjust the light and warmth entering your room for the perfect sleep environment tailored to your preferences.
Consistency: Using the smartphone app, set automated schedules for your UBlockout shades to lower or raise, ensuring your room remains dark during sleep hours, even when the sun is out.
Energy regulation: By controlling our exposure to light, especially in the morning, UBlockout smart shades can help regulate your circadian rhythm, ensuring your sleep-wake cycles align more naturally with light-dark cycles.
Can the shade be used with evaporative air coolers?
Yes, our shades can work in rooms with evaporative AC.
Please note our 100% blackout shades create a complete seal around windows that reduces airflow from outside - which evaporative AC systems typically require. Shade tension can be adjusted post-install to ensure your AC works as expected, and our support team are available to resolve any troubleshooting.
Can the shade be mounted to windows with existing fixtures and fittings?
Yes, our shades are often installed behind curtains, plantation shutters or other existing window furnishings, depending on mount type and positioning.
If you're unsure, please send us a photo of your existing window and we can help design a shade for your space: support@ublockout.com

Egress Risk
Customers should evaluate and consider the specific safety risks associated with the suitability of UBlockout shades for their particular environment and circumstances.
UBlockout shades are retrofittable and retractable and are offered in inside and outside mount configurations. The specific dimensions and specifications of the shades are provided on our website. Installation of a UBlockout shade may obstruct or delay entry or exit from a window or door in the event of an emergency or otherwise.
Installing UBlockout in addition to existing blinds/shades may further obstruct or delay entry or exit.
Motorized shades have an inherently increased obstruction risk as they will not function without the motor being charged and the remote or smart control app functioning.
For more information see UBlockout safety terms and our terms and conditions of sale.
