Which Curtain to Choose for a Bedroom: A Guide by Priority
A bedroom curtain is chosen by three priorities: darkness for good sleep, thermal comfort in summer and winter, and quiet against noise. For most bedrooms, total blackout is the decisive criterion, because darkness triggers melatonin production and improves sleep. The Kurtens curtain, at 620 gsm, blocks 100% of light*, holds back up to 7 °C of difference* and attenuates up to 22 dB*, covering all three needs in a single curtain.
To choose, rank your priorities: sleeping in the dark, keeping a good temperature, or finding quiet, knowing that a technical curtain answers all three at once.
Priority 1: darkness for sleep
In a bedroom, blackout is the first criterion. Total darkness, below 1 lux, promotes falling asleep and deep sleep, while the smallest light leak disrupts the cycle. A high-performance blackout curtain blocks light from the street, streetlamps and early morning. The difference between 95% and 100% blackout shows in use: only full darkness guarantees real rest. For the detail of the link between light and sleep, see our dedicated article on blackout curtains for the bedroom and sleep.
Table: which curtain for your bedroom priority
Here is the dominant priority of a bedroom and the suitable answer.
| Priority | What you need | Kurtens answer |
|---|---|---|
| Sleeping in the dark | Total blackout | 100% of light blocked* |
| Bedroom too hot or too cold | Insulation at the window | Up to 7 °C of difference* |
| Street noise at night | Mass in front of the glass | Up to 22 dB* attenuation |
| Ambiance and drape | Dense fabric, made to measure | 620 gsm, cut to exact dimensions |
*Data obtained under optimal test conditions. Real performance depends on exposure, glazing and fitting.
Priority 2: temperature, summer and winter
An exposed bedroom overheats in summer and cools at the window in winter. A thermal curtain limits heat exchange: closed during the hot hours, it blocks solar radiation; drawn in winter, it reduces the cold-wall feeling. It is an often underestimated sleep factor, as a bedroom that is too hot prevents falling asleep. If summer overheating is your main problem, follow our complete guide on the bedroom that is too hot in summer. The Kurtens curtain holds back up to 7 °C of difference*, summer and winter.
Priority 3: quiet against noise
If the bedroom faces a busy street, night noise fragments sleep. As the window is the entry point for noise, a dense curtain adds mass and attenuates the sounds passing through, under the mass law. The Kurtens curtain, at 620 gsm, attenuates up to 22 dB*, which clearly softens street noise. To understand what makes a curtain perform, see our guide on how to choose curtain weight.
The curtain that combines all three
Darkness, temperature and quiet coexist in most bedrooms. Rather than trade off, a technical curtain handles them together. The Kurtens curtain brings together three layers for 620 gsm: it blacks out at 100%* to sleep in the dark, holds back up to 7 °C of difference* for a temperate bedroom, and attenuates 22 dB* for quiet. Cut to measure to the exact dimensions of the window, it covers the whole opening with no light leak on the sides. Configure yours in the custom blackout curtains, thermal or soundproof collection.
The child's bedroom: a special case
In a child's bedroom, blackout helps with daytime naps and early bedtimes in summer, when it is still light out. Thermal comfort matters too, as small bedrooms overheat fast. A dense, blackout curtain cut to measure to cover the whole window answers both. The same logic as an adult bedroom applies, with extra attention to darkness to respect the sleep rhythm.
Sizing the bedroom curtain
Blackout and insulation only count if the curtain covers the whole opening. A curtain that is too narrow lets light in on the sides, one that is too short loses insulation. Made-to-measure, with the recommended overlaps, removes these leaks. Compare the functions in the custom curtains collection.
Frequently asked questions
What is the most important criterion for a bedroom curtain?
Blackout. Total darkness promotes melatonin production and deep sleep. The smallest light leak disrupts the cycle, which is why a curtain that blocks 100% of light*, like the Kurtens curtain, makes the real difference in a bedroom.
Can a bedroom curtain also insulate from heat?
Yes. A thermal curtain closed during the hot hours blocks solar radiation and keeps the bedroom cooler, which helps sleep in summer. The Kurtens curtain holds back up to 7 °C of difference* and also works against cold in winter.
Does a curtain reduce street noise in a bedroom?
Yes, partly. The window is the entry point for noise, and a dense curtain adds mass that attenuates sound. The Kurtens curtain, at 620 gsm, attenuates up to 22 dB*, which softens street noise and helps less fragmented sleep.
Do I need a different curtain per function in a bedroom?
No. A multi-layer technical curtain combines blackout, thermal insulation and noise attenuation. The Kurtens curtain, at 620 gsm, covers the three priorities of a bedroom with a single curtain, rather than layering several solutions.
Which curtain for a child's bedroom?
A blackout curtain helps with daytime naps and early bedtimes in summer. Thermal comfort matters too, as small bedrooms heat up fast. A dense, blackout curtain cut to measure to cover the whole window answers both needs.
Key takeaways
A bedroom curtain is chosen by priority: darkness for sleep first, then temperature and quiet. Total blackout is the decisive criterion, but a comfortable bedroom often needs all three functions. A technical curtain combines them: the Kurtens curtain, at 620 gsm, blocks 100% of light*, holds back up to 7 °C of difference* and attenuates up to 22 dB*, cut to the exact dimensions of your window.
