Blackout Curtains That Actually Block 100% of Light
Most blackout curtains block some light. But light still leaks around the edges, through the top, and between the curtain and the wall. Whether you call them blackout curtains, blockout curtains, or block out curtains, the problem is the same: none of them seal the light at the glass.
My Blackout seals directly to your window glass, blocking 100% of light with zero gaps. No curtain rod. No drilling. Installs in 30 seconds and comes down just as fast.

Why Most Blackout Curtains and Blockout Curtains Fall Short
You have probably tried blackout curtains before. Maybe more than once. Whether you bought blockout curtains from Spotlight, block out curtains from Kmart, or something online, the result is always the same: light leaks in around the edges.
Traditional block out curtains hang from a rod, which means there is always a gap at the top where light pours through. The sides never sit flush against the wall, so light creeps in there too. And if the curtains are not wide enough, you get a bright strip right down the middle.
How to Stop Light Coming Through Curtains
This is one of the most common frustrations with blockout curtains. People try blackout curtain liners, but they add weight, make curtains harder to open and close, and still leave the same edge gaps. Some people try makeshift blackout curtains with cardboard or garbage bags, but those solutions look terrible and fall down within days.
The truth is, blockout curtains were designed for privacy and decoration. They were never designed to create total blackout. For that, you need something that seals against the glass itself.
How My Blackout Works
My Blackout attaches directly to your window glass using industrial-strength suction cups. A Velcro seal runs around the edges, closing every gap where light normally leaks through.
It is lightweight, stick-on, and requires zero tools or drilling. You can install it in under 30 seconds and take it down just as fast.
Attach
Press the blackout curtain suction cups directly onto the window glass. They lock into place with a firm twist.
Seal
Use the blackout Velcro curtain strips to create a light-tight seal around the edges. No gaps, no light bleed.
Done
A completely dark room in under 30 seconds. Remove it whenever you like and pack it into the included carry bag.

Finally, real blackout
I tried three different sets of blackout curtains before finding My Blackout. None of them actually blocked all the light. This does. The suction cups hold strong and there are zero gaps.
Night shift lifesaver
I work night shifts and blackout curtains were not cutting it. My Blackout seals right to the glass so no light gets in at all. I can finally sleep during the day.
Better than $400 custom curtains
Was about to spend $400 on custom blackout curtains for the bedroom. Found My Blackout instead. Better result, a fraction of the price, and I can take it with me when I move.

Frequently Asked Questions
The most effective way to block out light from windows is to seal the light at the glass, not at the curtain. Traditional blackout curtains hang from a rod and always leave gaps around the edges where light leaks through. My Blackout attaches directly to your window glass using suction cups, creating a seal that blocks 100% of light with zero gaps. No curtain rod needed, no drilling, and it installs in 30 seconds.
Most blackout curtains and blockout curtains block between 85% and 95% of light, but they almost always leak around the edges, through the gap at the top of the rod, and between the curtain and the wall. This is a common frustration for people trying to stop light coming through curtains. For true 100% blackout, you need something that seals against the glass rather than hanging in front of it.
Standard blockout curtains are better than regular curtains, but they rarely deliver the total darkness they promise. Light still leaks around the edges, they require drilling a curtain rod into the wall, and they are not portable. My Blackout costs a fraction of custom block out curtains and actually blocks 100% of light because it seals to the glass. It also comes with a money-back guarantee, so you can see the difference before committing.
Room darkening curtains typically block 50% to 70% of light, while blackout curtains claim to block 95% or more. In practice, even blackout curtains leak light around the edges and top of the curtain rod. Neither achieves true total darkness. My Blackout seals directly to the glass with suction cups, which is the only way to block 100% of light without custom fitted window channels.
Some cheap blackout curtains use PVC coatings, chemical plasticisers, and dyes that have not been safety tested. This can be a concern in bedrooms where you spend hours sleeping in a closed room. My Blackout uses OEKO-TEX certified fabric that has been independently tested for harmful substances, along with BPA-free locking suction cups. No chemical odour and safe to use from day one.
My Blackout attaches directly to your window glass using suction cups. No curtain rod, no brackets, no drilling. It seals against the glass to block 100% of light, giving you a better result than traditional blackout curtains without any of the installation hassle. It installs in 30 seconds and packs into a carry bag when you do not need it.
Traditional blackout curtains require a curtain rod, which means drilling into the wall or window frame. If you are renting, this can put your bond at risk. My Blackout uses suction cups that attach to the glass, so there is zero drilling, zero screws, and zero wall damage. It is the ideal blackout curtain alternative for renters or anyone who does not want permanent fixtures.
Light leaking from the sides is the biggest problem with blockout curtains. It happens because curtains hang from a rod and never sit flush against the wall. Some people try adding curtain side channels or magnetic strips, but these are expensive, fiddly, and still leave gaps at the top. My Blackout solves this completely because it seals directly to the glass with a Velcro edge seal that closes every gap, including the sides, top, and bottom. No side light, no top light, total darkness.
