Blackout window treatments

For a completely dark room, you need window treatments that block 100% of light. Blackout fabrics have a special coating on the back that stops every ray of light. But the fabric alone is not enough: light gaps along the edges must also be addressed. Roller blinds with side channels seal the fabric on all sides. Honeycomb blinds with blackout fabric block light and insulate the window. The ultimate solution is a combination of blackout roller blinds with curtains: the blind blocks the light, the curtains cover any remaining edges.

Tips

Blackout coating

Always choose fabric with a blackout coating on the back. Dark fabrics without coating still let light through. The coating is the key to true blackout.

Side channels

Side channels seal the fabric at the sides, preventing light gaps. Essential for true 100% blackout.

Double layer

Combine blackout roller blinds with curtains. The blinds block light, the curtains cover the last edges and dampen sound.

Frequently asked questions

Which window treatment blocks 100% of light?

Roller blinds with blackout fabric and side channels come closest to 100% blackout. Combine with curtains for the ultimate result. Honeycomb blinds with blackout fabric also offer excellent light blocking plus insulation.

Is a dark fabric always blackout?

No, a dark colour does not automatically mean blackout. True blackout fabrics have a special coating on the back that blocks light. Without this coating, even a dark fabric lets light through. Always check if the fabric has a blackout classification.
