Product Description
A professional acoustic curtain combining sound insulation and sound absorption, to improve the acoustic comfort of the space.
The curtain is made of 100% polyester and is constructed from three main fabric sheets that form five functional layers.
The outer layer has a waffle texture, which helps reduce sound reflections and reverberation inside the room. The inner layers include a dense fabric and a dedicated coating, which help reduce sound transmission through the curtain.
The unique construction and the high weight of the fabric combine acoustic improvement, blackout shading and thermal insulation in a single solution.
Acoustic Performance
The curtain helps reduce everyday noises such as speech, television, musical instruments, barking dogs and street noise.
- Particularly effective at medium and high frequencies, above approx. 1,000 Hz.
- Reported noise reduction in the range of 8–25 dB, depending on test conditions.
- Reported average reduction of approx. 12–13 dB.
- Helps absorb sound and reduce reverberation within the space.
Important to know: Actual acoustic performance varies with the noise frequency, the window construction, the curtain size and the installation method. The reported reduction values are not guaranteed in every installation.
Thermal Insulation
The multi-layer construction helps reduce heat transfer through the window area and maintain a comfortable room temperature.
- Helps reduce heat gain in summer.
- Helps keep warmth inside the space in winter.
- May help reduce energy consumption for heating and cooling.
- Reported thermal improvement of up to 66% under test conditions.
Installation
- It is recommended to install the curtain so that it covers the entire window opening.
- Keep gaps at the sides, top and bottom to a minimum.
- Can be installed using the supplied hanging hooks, according to the installation kit.
- Tiebacks can be used to gather the curtain as needed.
Covering the opening as fully as possible helps improve the acoustic insulation and blackout performance.
Care and Cleaning
- Regular dusting with a vacuum cleaner is recommended.
- Can be hand washed gently at up to 40°C.
- Do not use bleach.
- Drying in the shade is recommended.
- Avoid frequent washing and follow the care label instructions.
Fire Resistance
The product is not classified as fire-resistant or flame-retardant.
Further Details, Questions and Answers
How strong is the noise insulation effect compared with regular curtains?
In numerical terms, the noise insulation effect ranges from 8 dB to 25 dB, with an average of 12.5 dB
For example, in the case of piano sounds, the sound can be reduced from loud to only faint, to a level that is no longer disturbing,
by installing noise-blocking curtains. The noise insulation effect varies greatly depending on the conditions of the customer’s room and the installation method.
It is best to have no gaps
The noise insulation effect is stronger when there are no gaps. Sound can pass through any gaps, so it is best to avoid gaps as much as possible.
Does the 5-layer construction mean the curtain is made of 5 pieces of fabric?
No. Two of the three fabric sheets are coated, which gives the fabric its 5-layer construction.
How many hooks do they come with?
It depends on the size. For example, a ready-made size 110 cm wide comes with 8 hooks attached to the curtain.
Are they effective at reducing outdoor noise from cars or trains?
The sound will be reduced to some extent, but it is likely to be less effective than hoped for deep bass sounds such as car engines.
Can the curtains be repaired?
We do not offer curtain repairs.
Are they effective for controlling noise from musical instruments?
It depends on the instrument, but it is very likely the sound will be reduced to some extent.
For example, in the case of piano sounds, installing noise-blocking curtains can reduce a sound that was previously loud so that it is still heard but is no longer disturbing.
Do you sell the curtain fabric on its own?
No, we do not.
Can they be machine washed?
Based on the product specification, the curtains cannot be machine washed due to the thickness and weight of the fabric. Please dry clean or wash them by hand.
Will the noise insulation effect decrease after washing?
We do not believe the noise insulation effect will decrease, even after washing
