Blackout curtains (or blockout curtains) are curtains designed to block all light from entering the room. Although most effective when a dark colour, blackout curtains do not have to be black. A wide range of colours, patterns, and thicknesses of curtain fabrics are available on ArchiPro, all of them sourced from trusted suppliers across Australia.
Good quality blackout curtains should block 100% of the light that would normally pass through the curtain.
