How to choose your size
Two measurements are all you need: the width of the opening and the height. Standard sizes or made to measure, down to the centimetre.
The width of the opening
Measure your window from edge to edge. Fit the rod 15 cm above and extend it 15 to 20 cm on each side: the window looks larger and the light is freed up. Order a curtain width of 2 to 2.5 times the width of the window: the full folds dress the room and trap air, which strengthens both sound and thermal insulation.
The height
Measure from the top of the rod down to the floor. The curtains should just brush the floor, or fall 1 to 2 cm onto it for a softer, gentle break. Avoid letting them stop above the floor: the room looks smaller and draughts get through.
Exact-Fit guarantee. A measuring mistake within 30 days, and we remake your curtain free of charge. Order without fear of getting it wrong.
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.
How to choose your heading type
The right choice depends first on your rod. Identify your setup, and the rest follows.
Eyelets ★★★
For: round rod Ø 16-35 mm Even waves, modern look.
Pencil pleat ★★★
For: track or rings with hooks Even pleating, premium finish.
Rod pocket ★★☆
For: thin round rod Threaded straight on, no visible hardware.
Multi-function ★★★
For: all rods Pencil pleat + rod pocket + hooks. You choose on delivery.For maximum blackout, the pencil pleat and the rod pocket close better at the top. Eyelets let a thin trickle of light through around the rings.

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
Green brings nature indoors. A calming color par excellence, it transforms your room into a haven of serenity while offering complete thermal, acoustic, and light insulation.
Three performances combined in a single curtain, made to measure or in standard sizes
Our Serenity green curtain is a thermal and acoustic blackout curtain, available made-to-measure or in standard sizes, designed to simultaneously address three issues: noise, cold, and light. Thanks to its 3-layer construction and 620 g/m² weight, it achieves a level of performance that few curtains on the market can claim.
Green: for which rooms and for what uses?
This color is a natural fit for bedrooms, meditation spaces, and offices. Green promotes concentration and relaxation—two qualities enhanced by the -22 dB sound reduction of our 3-layer fabric.
A curtain made to your exact dimensions
Each Serenity green curtain is made in our workshops to your precise measurements. You choose the height and width you need, without any limits. Whether you have a 3-meter bay window, a standard French door, or a bedroom window, your curtain adapts to your interior, not the other way around. The result: optimal insulation with no gaps at the sides, a perfect drape, and a bespoke finish that standard-sized curtains simply cannot offer.
Decorating tips and associations
Pair green with white, cream, or terracotta walls. It combines well with natural materials like raw wood, wicker, linen, and touches of gold for an organic and refined interior.
