Our curtain as far as we can see against our competitor's (February 2020-March 2023) product is the only product actually tested with a double glazed window. Our testing has been performed in February 2020 and was with a real-world set up and performed in a laboratory to record the results. The results show that the curtain reduces sound entering a space by 4 Decibels when combined with a brand new standard double glazed window.
When tested without the window in an open space it tested to 11 decibels. Obviously, when working with a window, the window is doing the majority of the acoustic reduction.

Frequently Asked Question About Sound Proof Curtains
- This all depends on how your room is constructed and most importantly the windows that are in your room. If you have a draughty window made out of single glazing then our curtains will work well to reduce the sound entering and passing around the room. The curtains have been tested for sound insulation effectively sound blocking. The tests performed in the laboratory have shown the insulation 4db of insulation with a double glazed window. However, the sound blocking is totally dependent on the structure of the room and windows. We have picked a standard test of double glazing in a block structure room and we got the 4db result.
Customer Review - Triple Glazed windows in a modern London apartment. Our customer has said there was a 50% reduction in the sound.
Road Noise is generally low tones when on the roadside, so if on a ground floor level the sound is probably entering through the fabric of the building. This means your adjustments will need to be more structural. For higher frequencies, these curtains will work well to dull the sound.
Similar to road noise it depends on the construction of your room
We have had customers note - they have seen upto a 50% improvement when using double glazing and our curtains. They can now sleep through the the early morning flights. Modern buildings with quality double glazing units will only see a marginal impact from the sound entering the room. Where you will notice the improvement is the sound already bounces around the space. As you are adding an acoustic absorber being the face fabric to the space, it will reduce the reverberation of the sound passing around the space.
Read this carefully. There is no difference between the 2. We just like to explain the product for one use and another for a different use. The room divider curtain has been tested as a room divider so has a sound insulation of 11db varying on lining and the window curtain has been tested infront of a double glazed window so has a 4 db uplift above the double glazed window.
When working with loud echoes in spaces it can be incredibly frustrating to stop sound reverberating around the room. This is where an acoustic curtain come in. Depending on the fabric it will have a varying effect on the amount of absorption that It takes and effects the sound passing back around the room.
To see how good a fabric or product is at absorbing sound in a room then you need to complete the Sound absorption test EN ISO 354. This grades a product between A – E based on how absorbent a material is. When sound is projected into a room it will hit the surfaces and then it will either be transmitted through things like ceilings and walls or it will be reflected back into the room. So in a basic form, the test is how much sound is sent out will return.
Example Imagine. 100 units of sound are sent into a room, 95 units are transmitted out of the room and then 5 are recorded back into the space.
Thus the sound absorption coefficient is 0,95Sound insulation is the measurement of sound passing between 2 spaces when comparing its performance in an aperature that is open and then sealed with the test product. This is tested with ENISO 717 for acousitc insulation. This is measured in decibells and is measured to show the reduction of sound.

Customer Reviews
Ordered samples arrived promptly as promised. Excellent information and friendly follow-up. Good to find a company that cares about customers. Thank you.
I purchased sound absorbing curtains for my studio, and was so pleased with the quality of these, that I suggested my wife order new bedroom curtains. We wanted black-out, and again very pleased. Great products and service.
We have used these many times now and they are fantastic, great communication great products would recommend them 100%.
High quality made to measure curtains helped somewhat to reduce outside traffic noise would consider buying more for others part of the house.
Superb curtains of great quality. The only gripe would be slight long lead time, but the wait was worth it.
Good quality curtains that are dampening external noise as advertised.
Got these and was really disappointed so contacted the team. They called back and couldn’t be more helpful, talked through fitting etc and they were concerned that they might not work so well because I have acoustic glass already but suggested I try a better curtain track positioned higher on the wall. They sent this to me free of charge. Happy to say that this made all the difference and the road noise is now dramatically less and I can sleep well! Totally recommend
Easy ordering process, quicker than expected delivery and excellent quality curtains
Very helpful staff. Respond very quickly to emails. The curtain was ready quicker than the estimated and arrived carefully packaged. The video links sent on how to get the best from your curtains was incredibly useful.
A quick response to my query and staff were helpful. I'm pleased with the curtains.
The curtain is well made and good quality. Not tested it yet to see how much it absorbs sound.
They were able to get a previous order up, which saved me a lot of time. Very helpful on the phone and quick to reply
.
Excellent Product
First of all I really enjoy reading Trustpilot reviews because simply put I trust them and people who bother writing them seem to want to help future consumers make better choices. With this in mind I want to say that all my dealings with Direct Fabrics have been absolutely brilliant. I had spent months, literally, seeing other companies about blinds and curtains and none of them were able to do what I needed and I kept changing my mind about what I really needed. I ended up deciding that I needed curtains that were both blackout and soundproofed and happened on Direct Fabrics through Google. Now I'm not handy at all but speaking with Jane Lovell who is Snr Sales Administrator I felt brave enough to measure up the rather large and tall windows. The price was incredibly reasonable for what I needed and the track which was a tricky shape arrived incredibly quickly and fit perfectly. The curtains arrived later and are just beautiful. They have blocked off the light and made my bedroom soundproofed as much as I needed. The workmanship, and I'm very picky, is exceptional. It gives me huge pleasure to be recommending Direct Fabrics and a special mention to Jane for all her advice and patience, Georgina Thomson, Sales Administrator for keeping me in the loop re delivery and also why not mention Alana Thomas , Sales Administrator for letting me know my track was on its way. Thank you Direct Fabrics and only wish I wanted more curtains!!
Fast delivery and good online service.
This is a fantastic small British company. Knowledgable and wiling to share that knowledge with novices, so that you get the best soundproofing result possible. My project was to reduce noise in my therapy room where I see clients. I was very glad to have a nice range of colours to choose from, so that the curtains could be a decorative feature too. They look fabulous and are very effective, dampening the sound coming through the stud wall as I hoped they would. It was well worth the investment.
Amazing experience. Very happy!
Received my order in the time frame give. Really pleased with the quantity and product, the only thing I’m a disappointed with is they are a little short, I measured as advised and took 1.5 cm off length, but they are about 3” from floor. Besides that I’m really happy.
Response from Direct Fabrics
We are very sorry that your curtains are shorter than you expected / ordered. Please contact the team and we can investigate and ammend.
The rails arrived soon after placing the order and the curtains arrived a couple of weeks later, which was sooner than I was expecting. They are quality curtains and we are really pleased with the look and feel. The service was good throughout. The team were really helpful and able to answer all my questions, which helped me when making my decisions. While waiting for the curtains to arrive they sent me useful links to videos for getting the best finish.
Well made and very heavy weight curtains. Excellent light blocking with good sound dampening.
Arrived earlier than predicted which was a bonus.
Very helpful Customer Service during ordering stage.
Only Croatian would be they came tied off which was very difficult to untie to adjust with the cords fraying in the process.
Ordered custom made sound reducing blackout curtains. The curtains themselves are of great quality, completely block out the light and noticeable sound dampening effect.
The website was not the easiest but I got very quick help in the chat and everything was fixed to get the order made. The same person also answered emails quickly, literally in minutes, like checked availability of fabrics or status of order. The curtains were for my daughter and she is very pleased. They look lovely and makes the room very dark and she had not slept so well in weeks. Not completely soundproof but good help, since she lives across two night clubs. The curtains were easy to hang since they came with hooks already installed.
I ordered some bedroom curtains to help reduce noise as I live on a main road with a lot of early morning traffic noise. The curtains arrived very quickly and are a great colour, quality and finish and best of all they really do make a big difference reducing noise.
Very easy to order. Helpful on line service with good advice. We got two pairs of blackout curtains for our bedrooms and they have made a difference. Have cut down some of the sound from the street (they are not sound proof but have really made a difference) and the drafts from our old sash windows. Have made the room feel much cosier.. they are quite heavy so make sure your track is secure.
Great customer service. Great quality acoustic window curtains, helps reduce some of the higher pitched noises from the busy road we live on.
These curtains are beautifully made. They hang beautifully. I am so pleased with them. And they do help with the noise of the busy main road that we live near.
Great Product
Lovely customer service and support throughout the buying process (including sending fabric samples to help decide materials)
Amazing company, very responsive on emails and extremely helpful in ordering and helping with the measurements for the curtains. Cannot praise the professional service enough. Will definitely be using again. Ordering from this company you cannot go wrong
Excellent service from the 1st enquiry all the way to delivery - thank you! Really helpful, knowledgable and the product was excellent - It was a very specific requirement for a theatre curtain with excellent acoustic and blackout properties. Recommend highly.
Brilliant service, nothing is too much trouble. Curtains are excellent quality. I would definitely use again.
Great service and product once again. These are the second set of curtains I have purchased and both are fantastic. Would definitely recommend.
Excellent service. Excellent product. The curtains were with us sooner than expected. Good quality. Very happy customer
Good quality produc. About the sound reduction, didn't measured it, but there is definitely a reduction. Would recommend.
Brilliant experience with ordering through Direct Fabrics. The sales team were absolutely amazing and super attentive/responsive. I was kept up to date with my order and the quality of the curtains I ordered for my place of work were of the highest quality. I highly recommend Direct Fabrics!
Great quality as always. Love this firm. Such well made curtains. Measurements are spot on.
Lovely curtains
Came with hooks attached which was a bonus. We wanted soundproofing as we are on a flight path and these definitely help
The service from start to finish was first class. The curtains are very well made and look great. They reduce the external noise and are completely blackout. I would definitely recommend.
Delay in delivery due to supply problems, but excellent customer service and product and delivered when they said they would. Thanks.
Nicely made , perfect fit , arrived quickly
my second order
We live near a busy airport and so have aircraft noise often during the night. We decided that sound reduction curtains would be a good idea. I "Firefoxed" sound reduction curtains and very fortunately for us Direct Fabrics was suggested. They have a YouTube channel which I would recommend you watch.
We requested some sample fabrics (which are free) and they arrived within a couple of days. There is an excellent choice so you will have no problems finding one you like.
We would like to thank Lizzie for being so patient with our questions and nothing was too much trouble for her.
We placed the order 14/10 and the curtain track arrived within a week. The curtains were delivered 12/11.
The quality is 10/10 and we are very pleased with the sound reduction. The aeroplanes are noticably quieter and the bedroom is pitch black! It is also warmer and the cat gives her thumbs up too.The dog's not too sure but he does what the cat says.
Thank you!
Quality and finish of curtains great
Great Service
Could not fault Direct Fabrics at all! They have been so helpful right from the initial quote emails through to me changing the sizing of the curtains and tracks numerous times. The acoustic curtains are perfect for our garden music studio and we would definitely buy from here again. Brilliant service all the way through, thank you.
From my first enquiry through to placing my order, the help and advice from the customer services was exceptional.
Now my curtains have arrived and definitely live up to my high expectations.
I am delighted.
Purchased the acoustic curtains & heavy duty track. Both the noise reduction (of distant traffic on a busy road) and the black out qualities of the lining & fabric, are very effective. Good quality material, which looks great. Thank you.
Would have been 5 star if had received notice of the delivery day.
Fantastic service and friendly people, great company.
Very good, extremely helpful !
Good service and product.
I was very impressed by the emails and phone calls with several people at Direct Fabrics whilst we tried to work out our order and they advised. The track arrived immediately and the curtains arrived much quicker than anticipated having been warned there might be a delay due to their supplies of fabrics being held up. The curtains were already pleated and hooked, thus ready to hang. The videos on their website give clear instruction about fixing the tracks. Great service.
I ordered some made-to-measure blackout acoustic curtains which were delivered quickly and to the exact size. The blackout function is excellent and the acoustic aspect certainly helps reduce traffic noise. The curtains are a bit stiff at the moment, but customer services advise me they will loosen up over time, although I can steam them to speed up the process.
The curtains arrived before I received the email advising that they had been despatched but luckily I was home to receive the package. Because of this I have docked half a star and have had to round down the rating.
Good curtains though, highly recommended.
Great service, helped me to realise a mistake I made with measurements.
Absolutely fantastic company. Excellent product, excellent service ( Thank you Georgina ). I highly recommend Direct Fabrics, they are a professional company with a friendly team of people working for them. The curtains we bought are of great quality and the service/advice I received was brilliant. Shop with confidence. Thanks.
Great value and high quality product backed by great service. The only reason I did not give a 5 star rating is that I would have appreciated notice of delivery.
Brilliant from start to finish ! Love the curtains x exactly as described !
Fantastic ! Absolutely love everything about the curtain ! Surprised they came ready to hang with metal hooks for 3cm pencil pleat ! Look wonderful !!!
No problems at any stage ! They sent fabric samples and curtains look amazing !
I stumbled across Direct Fabrics while searching for sound reducing curtains, online. I’m glad I did, for they were considerably cheaper than their main competitor, who were overpriced and had a poor selection to choose from.
Direct Fabrics, on the other hand, were very reasonably priced, for made to measure, and had a wide selection of colours and customisations to choose from. For example, you can choose from 5 different heading styles, if you pick ‘44mm eyelet’ you can select from 4 eyelet colours. You can also opt to have tiebacks included in your order, where applicable.
Overall, I’m very satisfied with my 4db sound reducing curtains. They are of good quality, slightly heavier than I was expecting, and do indeed help to reduce external noise, for me that’s a road, street and church bell. My curtains also have blackout layer, as standard, so they also double as blackout curtains, not to mention the thermal regulation that helps keep heat in and out.
Really happy with the curtains they have not been hung as yet but very good corespondent from start to finish
Very happy with the curtains. Great service and high quality.
I needed a sound proof curtain so I found Direct Fabrics on the internet. I found their staff very helpful in every way from start to finish with their advice. I received my curtain today and the professionalism is second to none and I found their prices very reasonable. Highly recommended gem and would definitely use Direct Fabrics again.
Natalia
Really happy with the product and the service, i would definitely use again.
Brilliant customer service, helpful throughout and very professional. Highly recommended !
Fabulous. Georgina has been helpful before and after sales . I am still trying to readjust the curtains but getting used to them. Very good quality and keeps the rooms super warm
Really pleased with my new sound-proof curtain. The colour and fabric are both great and it really does help reduce exterior noise.
The sales team responded quickly with any enquiries and helped me to select the best curtain for my circumstances.
I ordered curtains for bedroom windows to help reduce noise from road traffic and they have made a noticeable difference. Also the curtains act as blackouts and so serve two purposes. Delivery was rescheduled without a problem at my request. Thank you.

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
Selecting your Curtain Drop
Where to Measure From for Different Type of Curtains
Type of Curtains | Fitted On | Where to Measure from - to desired length |
Pencil Pleat Curtains | Curtain Track | Top of the Track - If using a extra wide track or designer track like silent gliss metropole, then measure from the underside of the track. |
Pencil Pleat Curtains | Curtain Pole | Measure from small ring at the bottom of eye under the ring, this is where your curtain clips into. |
Eyelet Curtains | Curtain Pole – Only | Top of the pole *we add on the upstand to our curtains, |
Pinch Pleat Curtains | Curtain Track | The underside of the track |
Wave Curtains | Curtain Track Designer Pole | The glider underneath the track. The curtain will sit under the track. |
Acoustic Curtains | See Heading Style of Choice above | Same but make sure wider than normal ideally 30cm past either side and 30 above. Also to the floor. |
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
