Home blackout curtains that aim to darken rooms, cut noise and help regulate temperature for more comfortable sleeping spaces. Ideal for anyone who needs longer lie-ins or quieter nights, while keeping rooms cosier year-round. Are Deconovo Blackout Curtains the right choice for city flats and light-sensitive households?

⚡ At a Glance
  • Light Control: 65%–80% room darkening efficiency, reduces early morning light and urban glare
  • Best for: People who need improved sleep, nurseries and city-centre flats
  • Not ideal for: Users who require complete blackout for shift work or home cinemas

Woven polyester panels reduce light transmission and help moderate heat transfer. OEKO-TEX Standard 100 certified fabric keeps a soft, durable finish.


Darker Rooms for Better Rest - with 65%–80% room darkening efficiency

Multi-layer woven polyester construction reduces light penetration, with manufacturer guidance to choose curtain width 1.5–2 times the pole and to measure drop from pole to desired length. The design aims to block early morning light and urban glare rather than produce total blackout.

Creates a noticeably dimmer bedroom that supports longer lie-ins and fewer sleep interruptions, especially useful for light-sensitive sleepers and nurseries.

Warmer Winters and Cooler Summers - thanks to thermal insulated fabric

Specially designed polyester weave reduces heat transfer by adding an insulating layer between glass and room air, helping to maintain a steadier indoor temperature throughout the year.

Helps keep rooms cooler in summer and warmer in winter, contributing to less reliance on heating and cooling and potential long-term energy savings.

Quieter Rooms, Less Street Noise - with noise-reducing woven polyester

Dense, lightweight polyester resists wear while offering sound-dampening qualities typical of woven textiles, suitable for bedrooms, nurseries and city-centre flats.

Reduces ambient noise enough to improve sleep quality and create a calmer living environment, particularly in noisier urban locations.
