Most other "blackout" curtains are just "room darkening," meaning they let about 10% to 25% of light filter through.

Sleepout fabric is a proprietary 100% blackout material. It features a specialized water-based coating that ensures zero light penetration, essential for maintaining your circadian rhythm and boosting melatonin production.

Curtains falsely marketed as "blackout" often use black or gray color backing materials in an attempt to block more light. Black backings are well known to shatter glass windows because they absorb heat and they are not allowed in HOAs, condos or apartments.

Since Sleepout® is 100% blackout, we use an elegant, premium white color backing that reflects sunlight to save on energy bills, protect your windows and look beautiful from the outside.

Sleepout is the first blackout curtain made with a water-based process instead of harmful chemical solvents. This breakthrough allows our fabric to meet the highest safety standards in home textiles, including OEKO-TEX® Standard 100 Class 1, the same level of chemical safety required for infant clothing, tested against over 15,000 chemicals.

Sleepout is the only blackout curtain to ever earn GREENGUARD® Gold certification. After more than 25 years, no other blackout curtain has passed this test.

Sleepout curtains are made for a lifetime, not seasonal replacement. Our fabric is made with thick woven threads and a four layer coating process that delivers exceptional durability while remaining light-weight to help block outside noise and protect your privacy.

This advanced construction allows us to offer one of the highest warranty standards in the industry, because these curtains are built to perform year after year.
