Size: 140cm is the width of the fabric, if you order wider than that we will sew it to the 140cm fabric.

The sewing of the curtains is not an extra cost!

The overall breadth of the soundproof curtain is 140cm. If you need a wider one, it can also be solved (by sewing together). So there will be one seam every 140 cm.
The length can be chosen by the customer. Don’t forget to measure the height of the cornice! It is very important to measure everything accurately, whether it is a window, a door, or a partition blackout curtain!

As usual for curtains, the curtains should be wider twice than the width of the window, but we recommend two and half times the breadth to make soundproofing more efficient.

Remember to measure and plan accurately! So the result will be as you imagined.

Do not send us the sizes of your window, or door, we only need the sizes of the curtain you want!

Paste mount:

The Helio soundproof curtain can also be hung with tweezers, curtain heading tapes, or possibly a ring/a grommet. We charge extra for rings/grommets!

Note that the soundproof fabrics are heavy and dense, so think about what size blackout curtain you want to place and also where!

Tweezers: the traditional mount (we just use nails to hang the fabric)

(tweezers and hooks are not sold!)


These mustn’t be traditional materials! They are thick and much denser, therefore they have the best acoustic, thermal insulated, noise reducing, and soundproof properties. So, it is important to design and weigh where we want to place the drapes! Soundproof drapes are easy to install.

Calculation of sizes of the soundproof curtains:

Their width is uniformly 140cm, count around 2-2cm due to the hem! If you want a blackout curtain wider than 140 cm, an additional 5 cm must be counted every 140 cm. The cornice “hide” of the sound-absorbing curtain is about 8-10 cm more. For individual needs, send an e-mail!

Think through all the details before ordering, because we cannot replace or take back the curtain that has already been made!

As we know, not only the excellent efficiency but the appearance of the Soundproofing panels and diffusers and the sound insulating curtains is also very important. They fit perfectly with the other Perfect Acoustic products, both in color and design! This way, not only the sound, but the overall picture will be perfect.

A few words about acoustics

Soundproof property:

Acoustics is a complex discipline. We’d like to explain it briefly and simply why it is so important. If we are in an empty room the sound is very echoing and unpleasant. Everyone has experienced this before. (Many people think that at this point it is enough to stick a pile of “egg cups” in the room! That’s not true! Don’t believe everything !!) As we start to decorate and furnish it, the acoustics of the room will get better and better. If we put the furniture, drapes, and decorations in the right places, we can get a more favorable sound.

The importance of good acoustics in a home is different than in a hi-fi, movie room, or studio. For these rooms, the high and low tones must sound proper. This requires conscious planning. I would mention ONLINE design here. This way, you can avoid buying more products than necessary. With this solution, we don’t have to run in circles! (Of course, it doesn’t matter what material the building was made of.) The best sound is available with acoustic panels and diffusers!

Glass is one of the worst surfaces.

The panels and diffusers can be placed in the optimal place. But what about glass surfaces? The  Soundproof Curtain can provide a solution to this. It complements other acoustic products due to its specially developed material! These materials have several benefits. They are soundproof, noise-reducing, thermal insulated, and good-looking!

So it can “replace” the other acoustic elements.  The thermal insulation properties can be well exploited in every season! In cinema rooms and our bedroom, the complete darkness can be feasible.

Of course, design is not the last aspect either. In a well-furnished, pleasant room, one feels much better. So when we are in a good mood, relaxed and focused, our performance also improves in all areas of life. A room with poor acoustics is tiring to the ear and can cause headaches and even depression. It is important to create a room where we are happy to have fun!

The best solution

Sound insulating curtains are effective in reducing noise and unwanted sounds in our homes. Glass surfaces reflect sounds, causing annoying echoes. The best solution to this problem is a soundproofing curtain.

Noise problems

Persistent noise from the street, through the window, can disturb the silence of our home and bedroom. Soundproof, thermal-insulated, blackout curtains are made of the highest quality fabric and, thanks to their thick, dense weave, have several functions at once.

Too much bass

Most bass is collected along hard, flat, expansive walls, ceilings, and window surfaces. These surfaces are not able to absorb sound, so it is necessary to attenuate echoes in our home or studio by placing soundproof elements and curtains.

Multifunctional fabric

Sound absorbing curtains can be used in several locations. Thanks to its excellent soundproof fabric, it is extremely effective at home, at work, and in studios. Complete darkening is essential in cinema rooms, which can also be achieved with these soundproof fabrics. The Helio soundproof and blackout curtain is made of specially developed materials, so they have excellent noise reducing and of course thermal insulating properties! Because of these features, they can be used effectively for the perfect acoustics, supplemented by the other Perfect Acoustic products (acoustic panel, sound diffuser, etc.)!

Noise-reducing curtains

Can’t you sleep? Are you constantly tired and tense? Are you exposed to constant noise at home and in the office? Do you feel you have no energy? If the answer to these questions is yes, search no further for the reasons! It is almost certain that some of your problems are caused by noise exposure. Sounds reflected from the surface of the wall, ceiling and windows create unpleasant echoes. Echoes severely degrade the quality of the audio you listen to and result in noisy sound. Acoustic treatment of the wall and ceiling can be solved with wall panels. Place noise-reducing curtains in front of the windows, so noise reduction improves the acoustics of the apartment or office.

Coming home after an exhausting day, we can be recharged with energy. However, this requires peace. Noise reduction and light blocking can result in peaceful, restful sleep. We can also make the office atmosphere more pleasant with a beautiful and practical blackout curtain.

Even in castles and mansions built in the last centuries, velvet blackout curtains were used for light blocking, noise reduction, and insulation. These velvet blackout curtains usually range from ceiling to floor.


1. Each curtain is made based on an individual order, therefore each curtain is considered unique, and we cannot buy it back!

2. The weight of the curtains refers to the flow meter of the material: 1 flow meter is 140 cm and weighs 820 grams. (+/- 20-30% weight deviation possible!)

3. Acoustic curtains can only absorb 10-20 decibels of sound if they are placed completely without gaps or if the acoustics of the given room is adequate! Due to the resulting problems/complaints, we cannot take back the curtains!

In the case of an individual curtain order, it is no longer possible to modify or cancel the order after the order and payment, because we cannot refund the price!

There may be minimal colour variation between the curtains and cushion covers ordered.
