FAQs

Do blackout curtains really block all light?

Triple-weave blackout curtains block 95–99% of light. For total darkness, add a blackout blind or use Velcro-sealed edges to stop light gaps.

Do blackout curtains help with insulation?

Yes. Thermal blackout curtains reduce heat loss through windows by up to 25%, lowering heating bills in UK winters.

What is the best colour for blackout curtains?

Any colour works — the blackout layer is separate from the fabric face. Darker colours may block marginally more light at the edges.
