Example: 120 cm opening → 180 to 240 cm wide curtain.
Recommended minimum: 1.5× for performance. Ideal: 2× for perfect drape + maximum insulation.
For maximum blackout: extend to the floor; every centimeter of gap lets in light and drafts.
Why 1.5× to 2× the width?
Summary diagram
One curtain or two panels?
Two panels if your opening exceeds 250 cm or if you prefer to open from both sides.
Why do waves improve performance?
Folds create trapped air pockets that form an additional barrier against noise and cold. It's the same principle as double glazing; still air insulates.
How does the 3-in-1 work?
How does the 3-in-1 work?
A single curtain, three technical layers sewn together. Each has a measured role.
- The decorative face. A plain technical linen, with the drape of a heavy curtain. It dresses the window. The technology stays invisible.
- The blackout membrane. It blocks 100% of light and UV rays. You sleep in broad daylight, and your furniture no longer fades in the sun.
- The high-density technical backing. It insulates by up to 7°C: heat stays out in summer, in during winter, and your energy bill drops. It also attenuates outside noise by up to -22 dB: the street goes quiet.
Assembled, these three layers reach 620 g/m². It is this weight that gives the drape and carries all three functions.

100% blackout
The central membrane blocks 100% of visible light and UV rays. No halo at the edges, no streak of daylight when you wake. You sleep until the hour you choose, even in high summer.
The street stays outside.
The high-density layer absorbs street frequencies: traffic, neighbours, building works. Up to -22 dB measured at the window. Try it: close the curtain and listen to the volume drop.
Up to 7°C difference
The three technical layers form an insulating barrier. Heat stays outside in summer, inside in winter: up to 7°C difference measured at the window. Your heating and air conditioning work less, your bill drops.

Description
Beige warms a room without darkening it. A neutral, natural shade, it blends into almost any interior and softens daylight, while delivering blackout, thermal insulation and acoustic comfort.
Three functions combined in a single made-to-measure or standard-size curtain
The Beige Sérénité curtain is a blackout, thermal and acoustic curtain. Its three-layer structure and weight of 620 g/m² block 100% of light, insulate against cold and heat (up to 7°C gain) and reduce noise by 22 dB.
Beige: for which rooms and which uses?
Beige suits every room, from the living room to the bedroom. Neutral, it calms a busy space and brings out the furniture. In its blackout version, it delivers full darkness for nights without stray light.
A curtain made to your exact dimensions
The Beige curtain is ordered in standard sizes or made to measure, in width and height. It fits a patio door as well as a bedroom window, with no gaps at the sides and a clean drape. The heading is chosen between eyelets, gathering tape, rod pocket and multipurpose tape.
Styling tips and pairings
Beige pairs with raw wood, linen and natural tones. Next to white or cream walls, it keeps a room bright. With touches of terracotta and gold, it warms it up.
