Direct Fabrics are specialists in contract curtains and particularly Acoustic Sound Proofing Curtains. Our range is different to the others in the market place. Our sound proof curtains are actually tested in a laboratory. We have had them tested for sound insulation (sound proofing) to 13db and also sound absorbtion (echo reduction and sound clarity), "B" rating with lining" and a C rating on its own..
All this means that you can be confident in the product. Our curtains are great at sound blocking as a room divider, but when used with double glazing to stop road noise will not be as effective due to the window doing the majority of the work and the curtain focussing on the same frequencies as the window.
Style of your room Divider
You have a choice with room dividers of how they look on the reverse. If you want the room divider to be double sided please ensure you select double sided in the lining above.
Our Full Guide on Acoustics
This video we have put together to provide our clients with an understanding of our acoustic profits so people can see which product will work for them and what is the best option.
Understanding Acoustics - The main product discussed is the herringbone fabric
Video of our curtain working in an office
Quite simply our product is laboratory proven and has the following features;
- Proven to reduce sound passing between 2 spaces. It is certified depending on the number of layers up to 4db with a double glazzed window and 12db as a room divider for ENISO 1040-1
- A decorative product, as well as a sound blocking product.
- Hangs beautifully and works with standard curtain tracks and poles.
- Room Divider means no other obstruction stopping sound passing between a space
- If there is a door it will not work as well or a wall as the object is doing the work already
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. They have been tested to 4db with a sealed double glazed window.
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 road side, 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.
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 | Russle Of Leaves, Whisper | Very Faint |
0 | Threshold of Audibility | Nil |
YES - This is an excellent use of our acoustic curtains. standard acoustic herringbone fabric with acoustic lining is well suited to reduce sound passing from space to space at about 11db - 13db in a laboratory environment, combine this with our vinyl will get you approximately 10db in real-world testing. Laboratory.
Compared to the laboratory tests which have the fabric totally sealed you will not get a result as good as this in the real world. From our office tests and videos on youtube we have seen results of around 3db less in the real world. Going from 13db down to 10db area.
How to Measure For Curtains, Blinds and Tracks..
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 and more the window. Tested to 30cm
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

How to Measure for Blinds goinng 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 thesmallest 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
