Made to measure sound proof curtains, designed how you need them
We are here to help you choose the right product and lining option for your use case.
Choosing your curtain and lining options
- Unlined face only: for acoustic absorption and echo reduction (C rating absorber).
- 1 layer lining: 2db over a window, 10db as a room divider.
- 2 layers lining: 4db (estimated) over a window, 13db as a room divider.
- 1 layer lining plus face reverse: estimated 11 to 12db decorative room divider.
If you want a room divider to look good on the reverse side, select double sided in the lining options.
An acoustic curtain that works
Direct Fabrics specialise in contract curtains and acoustic sound proofing curtains. This range is laboratory tested for both sound insulation (sound blocking) and sound absorption (echo reduction and clarity).
The curtains perform best as a room divider because there is no other obstruction doing the work. Over a window, double glazing typically handles most of the insulation and the curtain improves specific frequencies.
Our full guide on acoustics
This video explains our acoustic options and helps you choose what will work for your situation. Main fabric discussed is the herringbone.
Video of our curtain working in an office
Our product is laboratory proven and has the following features:
- Certified performance varies by layers: up to 2db with a double glazed window and 10db as a room divider (EN ISO 1040-1 stated in your content).
- Decorative product as well as sound blocking.
- Works with standard curtain tracks and poles.
- Room divider results assume no other obstruction between spaces.
- If there is a door or wall doing the work already, the perceived impact is lower.

Frequently asked questions about sound proof curtains
This depends on how your room is constructed and most importantly the windows. Draughty or single glazed windows typically show the biggest perceived improvement.
In laboratory testing we observed a 4db improvement with a double glazed window in a block structure room. Real-world results vary based on gaps, flanking paths, and building construction.
Customer feedback example: triple glazed windows in a modern London apartment reported around a 50% reduction in perceived noise.
Road noise is often low frequency, so some noise may enter via the structure of the building. For higher frequencies, these curtains can dull the sound and reduce room reverberation.
Similar to road noise, it depends on the construction of your room.
Customers have noted up to a 50% improvement when combining quality glazing with our curtains. Where many people notice the improvement is reduced reverberation in the room because the curtain acts as an absorber.
Use a metal heavy duty curtain track. Our curtains are heavy. For example, a standard pair 200cm x 200cm can weigh around 8kg. We recommend our optimal track or our roller runner track. Roller runner track
There is no physical difference. We explain the same product for different use cases. Room divider tests show around 11db depending on lining, and window tests show around 4db uplift over double glazing.
Absorption is about reducing reverberation and echo inside a room. It is tested using EN ISO 354 and graded A to E based on how much sound is absorbed.
Simple way to think about it: sound hits surfaces and is either transmitted out or reflected back. The absorption coefficient indicates how much is absorbed rather than reflected.
Sound insulation measures sound passing between two spaces, comparing an open aperture versus sealed with the test product. This is typically measured in decibels to show the reduction, referenced in your copy as EN ISO 717.
| Changes in STC Rating | Changes in Apparent Loudness |
| +/- 1db | Almost imperceptible |
| +/- 3db | Just perceptible |
| +/- 5db | Clearly noticeable |
| +/- 10db | Twice (or half) as loud |
| Sound Level DB | Source | Sensation |
| 130 | Jet aircraft at 100ft | Physical pain |
| 110 | Thunder / artillery / disco | Deafening |
| 90 | Loud street / loud factory | Very loud |
| 70 | Cocktail party, noisy office, average street noise | Loud |
| 50 | General office, noisy home | Moderate |
| 30 | Private office, quiet home, empty gym | Faint |
| 10 | Rustle of leaves, whisper | Very faint |
| 0 | Threshold of audibility | Nil |
Yes. This is one of the best use cases. Laboratory tests show approximately 11db to 13db depending on lining.
Real-world results can differ from laboratory tests because sound can travel around the curtain via gaps and flanking paths. In testing, the track was mounted above the window and extended beyond the sides to demonstrate improvement.

Supplied and Fitted Acoustic CurtainsBuilding Contractor Feedback and Customer Feedback - name redacted. Shortly after the space became operational, demolition works began on the courthouse directly opposite the building. This has created significant challenges for the company (large plc), as the newly completed office functions as a presentation suite. The noise from the demolition is substantial and vibrations are clearly felt through both the walls and floor. This has led to ongoing discussions with the property agent, as this activity should have been flagged earlier in the process. What this situation has clearly demonstrated, however, is just how effective the curtain solution is. When the curtain is closed and a live presentation is running, the difference is immediately noticeable. The reduction in noise and vibration is not subtle, it is genuinely significant. This applies both to in room presentations and those being broadcast globally at the same time. The feedback from company has been extremely positive. The curtain has proven to be a critical element in maintaining the usability of the space under very challenging conditions, and everyone involved has been impressed by the level of performance it delivers.

Acoustic Curtain - great inventionI recently purchased an acoustic curtain to divide my shop into two spaces, and I'm extremely satisfied with the results. The product works very effectively to protect against noise from the shop, and I'm impressed with how well it blocks sound. The curtain is easy to install and provides a great solution for my needs. Overall, I highly recommend this product to anyone who needs to divide their space and reduce noise levels. Thank you for such a great product!

How to Measure For Curtains, Blinds and Tracks.
Pen and Paper
For recording your
measurements.
Helper
Someone to assist if your
windows are large .
Metal Tape Measure
As this will allow you to get a
rigid full length measurement.
Make sure your curtain tracks and poles are fitted in the position you want.
Choose the type of curtains that you would like and how you want to hang your curtains. See our heading styles guide
We recommend fitting your hardware first before measuring, this avoids any issues with not getting the perfect fit.
Measure your window using our main guide. Quick summary below. Remember wave, pinch, and designer headings require slightly different measurement
Measure in 3 places and take the shortest drop – Floors and ceilings can run out.
Double / Triple check your measurements
Choosing your Curtain Track Width
The width of the curtain track should extend past your window this allows for the curtains to stack back away from your window and allow light in.
Measure your recess and then add on 15cm on either side. For acoustics , we recommend further to fully cover the window and the surrounding area. In our test we added an additional 30cm to the width and also made the curtain floor length.
Wave curtains, for every 100cm of track the curtains will stack circa *18cm
Eyelet curtains, they will stack back circa 10cm per *70cm of track width
Pencil Pleat will stack approx 25% of the track width. eg. 210cm track will stack 52.5%
* all dependent on thickness of fabric

How to Measure for Blinds going Inside the Recess
- Measure the exact width of the recess in three places; at the top of the recess, in the centre of the recess and near the bottom - then take the smallest size.
- Measure the exact drop of the recess in three places on the left hand side of the recess, in the centre of the recess and on the right hand side of the recess - then take the smallest size.
- We will take one cm off the finished width size you have given us, to allow for the blind to pull up and down easily.
- Double check your measurements
- Cord Safety - Mounting Height - We ask for the mounting height of your blinds to allow for the cord to be 150cm off the ground. If mounting at 210cm This is what you enter in the Fitting height box. We make a deduction to ensure the cord is 150cm from the floor. Thus the cord loop will be 60cm
How to Measure Outside of the Recess
- Measure the recess in 3 places on the width and also 3 places on the drop. Take the widest measurement.
- Measure the width of the actual recess plus an additional amount – Usually from 7cm-15cm whatever you think looks appropriate. This is for overlap.
- Measure the exact drop of the recess. The blind would be fitted above the recess, so check the space above and add an amount on to the drop – usually from 7-15cm
- These sizes you have taken will be the size of the finished blind.
- Double check your measurements
- Cord Safety - Mounting Height - We ask for the mounting height of your blinds to allow for the cord to be 150cm off the ground. If mounting at 210cm This is what you enter in the fitting height box. We make a deduction to ensure the cord is 150cm from the floor. Thus the cord loop will be 60cm
Cubicle Tracks you have to measure with right angles from wall to wall where you want the track to go
Draw your room on a piece of paper with a sky view
Now measure from the wall to wall for straight tracks,
L Shape Tracks Measure to a point on the floor and mark with a piece of tape. Then for the other sides measure from the other wall to that point.
Always check for obstructions and fitting issues you may need to work around
