3 pass blackout fabric
If you want a truly dark bedroom, nursery or home theater, 3 pass blackout fabric is the material to reach for. Unlike ordinary room darkening fabric, it is built to stop light from passing through, so your curtains and shades can do their job even on the brightest mornings.
What Makes It Triple Pass Blackout?
The name comes from how the fabric is made. A base cloth is coated in three passes: typically a white layer, a black layer in the middle and another white layer on top. That dark center blocks light, while the lighter outer layers keep the fabric looking clean from both the room and the street.
Where to Use It
- Blackout curtain fabric for bedrooms, nurseries and media rooms
- Blackout lining fabric sewn behind decorative drapery panels
- Roman shades, valances and other custom window treatments
What to Look For
Check the width against your window measurements, consider how the hand and drape suit your project, and think about color on the outward face. Many shoppers also choose foam-backed blackout fabric as a thermal curtain lining to help with seasonal drafts and glare.
