Moondream Bicosy Soundproof Lining
1 LINING = 3 BENEFITS
Rediscover the pleasure of a quieter home without replacing your curtains. Fitted behind your curtain, the Moondream Bicosy lining combines noise reduction, thermal insulation and protection from light. A discreet way to improve comfort in your bedroom, living room or workspace.
➕ Tested acoustic performance
Thanks to its technical construction, this lining acts as a true acoustic barrier and is particularly effective against high frequencies, such as the sound of voices.
- Noise reduction: up to -8 dB⁽¹⁾
➕ Thermal insulation all year round
Featuring our THERMACTIV® technology, this lining helps maintain an ideal room temperature. Thanks to a metallised layer inspired by survival blankets, it reflects infrared radiation to keep heat inside in winter and reflect the sun’s heat in summer.
- In winter: retains heat indoors and enables up to 45% energy savings.
- In summer: reflects the sun’s rays and reduces the indoor temperature by up to 4.7°C⁽²⁾.
➕ Optimal blackout performance
Our LUMENCONTROL™ technology provides effective protection from light, ideal for bedrooms or spaces where darkness is needed.
Easy installation
The Bicosy lining attaches to the back of your curtain to complement your existing setup. Find the installation steps and techniques in our guide, according to your curtain’s heading style.
