Hemisphere is a high textured woven Dimout fabric with a very dense weave. This makes the structure and yarn visible on the surface, giving hemisphere some incredibly appealing characteristics. Available in a vast range of inspiring colours and amazingly versatile for a range of applications, the Hemisphere range can be used for face fabric, lining, trims and interior design accessories.
Those familiar with Direct Fabrics will know that our range of Dimouts are an extremely popular choice for hotels, universities, nursing homes, hospitals, domestic properties, and can also be used as a decorative window covering or form part of an overall interior design scheme. Hemisphere is no exception to the rule and ticks all the Dimout functionality boxes, and is accredited with all international Dimout standards.
Hemisphere Acoustic Curtains
The hemisphere range of curtain fabrics are an acoustic range of curtains, this means that they are ideally suited to reduce the amount of echo and reverberation of sound around a space.
The hemisphere range has passed a certified acoustic report. This means it is ideally suited for sound absorption as it is graded B for EN ISO 354:2003. It has passed the classification B standard so it will absorb a large amount of sound at a variety of frequencies.
Our curtain fabrics are selected and checked for quality issues and then we cut and measure everything by hand
In our UK based workrooms, we continue the traditions of master curtain makers and offer the very best curtains that are British Made Specification
Our curtains are manufactured with various fullness's to suit our customer's requirements. For standard made to measure curtains they are manufactured with 2x fullness also know as 100%. This means they you get beautifully pleated curtains.
Please see the further information section about curtain fullness
Which Curtain Lining Should i Use with Acoustic Curtains?
We have done tests in a working example with other fabrics and found that lining curtains adds mass to the curtain and means that there is more mass for the sound waves to pass through means less passes from space to space.
However, this test is a very good indication of the absorption benefits. Sound is like water and will find a way through at some level. As an example a window in a car when even slightly opened some sound will come through and obviously, the more open the more will come in. Therefore it will reduce sound passing between areas but it will never block entirely, the main benefit as stated previously is the echo and noise repeating around a room.
We recommend our Duo lining which is a blackout 3 pass lining with a fleece layer weighing circa 400gms. So this will double the mass of your curtain. Combining this with the double fullness of the curtain means you get a great absorption rating. Along with some sound block ability.
Our Office NON-SCIENTIFIC ACOUSTIC TEST - Indication to sound proofing
Within our test it shows using the curtain as a partition it goes with a vacuum on one side and the curtain open and drawn from 45 decibels reducing to 38 decibels. This fluctuates and is by no means a truly scientific result. However it was certainly noticeable in the office and reduced the vacuum sound and made the team able to communicate easily.

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
