How it compares

How to use it

1. Measure your window width and drop; add 10–15 cm for a full gather effect. For a standard UK window, choose 140x180 cm per panel.
2. Remove the curtain from the recyclable packaging and shake gently to release creases. Iron on low heat if needed.
3. Insert the curtain rod or track through the 4 cm header pocket. Alternatively, use the separate hook tape (sewn in) for standard curtain hooks.
4. Hang the curtain and adjust the folds by hand for a uniform appearance.
5. For maximum thermal effect, ensure the curtain overlaps the window frame by 5 cm on each side and touches the floor or windowsill.
6. Wash every 3 months at 30°C with similar colours, and tumble dry on low to maintain the blackout coating and softness.

These curtains have been tested for thermal efficiency by Which? (2026), which rated them a Best Buy for budget blackout curtains. Ethical Consumer (2026) notes that while Deconovo is not a certified B Corp, its OEKO-TEX certification and use of recycled materials in some ranges make it a reasonable mid-range choice for eco-conscious shoppers on a budget.

FAQ

Are Deconovo blackout curtains safe for children’s rooms?

Yes. The fabric meets OEKO-TEX Standard 100, meaning it is free from harmful chemicals like formaldehyde and heavy metals. The cords are not accessible on the curtain itself, but ensure your curtain pole or track does not have loose cords if used with a corded system.

Can I shorten Deconovo curtains without losing the blackout effect?

Yes, but carefully. You can hem the bottom by cutting and resewing, but avoid cutting the header tape or pocket. To maintain the thermal lining, use a sharp fabric scissors and fold the cut edge under twice before stitching.

Do these curtains block 100% of light?

No, they block 85–95% depending on the colour. Darker shades like grey and navy perform closer to 95%, while lighter colours let through a bit more. For complete blackout, choose a dark colour or layer with a blackout blind.

How do I clean these curtains if they get smelly from damp?

Machine wash at 30°C with a mild detergent, then tumble dry on low. Do not bleach or use fabric softener, as it can damage the blackout coating. Add a half cup of white vinegar to the rinse cycle to neutralise odours.
