Expectation setting: This is a dimout fabric designed to significantly reduce light levels. It is not a full blackout. For maximum light control, pair with an appropriate blackout lining.
Hemisphere Dimout – textured, dense and contract certified
Hemisphere is a high-texture woven dimout curtain fabric weighing approximately 320gsm. Its dense weave structure allows the yarn definition to remain visible on the surface, creating a strong textile character suitable for contemporary contract interiors.
Manufactured from 100% inherent flame retardant polyester, it is certified to BS 5867 Part 2C, EN 13773, IMO FTP Code 2010 Part 7, M1, B1, A1 and Classe Uno. It is also certified to STANDARD 100 by OEKO-TEX®.
In addition to light reduction, Hemisphere has been tested to EN ISO 354:2003 achieving a Class B acoustic rating, making it suitable for projects where reverberation control is required.
Where this fits in our range
Hemisphere sits within our heavier-weight dimout collection, offering more surface texture and acoustic performance than standard plain dimouts. For projects requiring full blackout, consider combining with a blackout lining.
Best suited for
Commonly specified for hotels, universities, healthcare environments, care homes and commercial properties where dimout performance and acoustic absorption are required.
Suitable for curtains, partitions and decorative interior schemes. When used with additional lining mass and appropriate fullness, acoustic performance can be further enhanced.
Available for supply by the metre or manufactured into made-to-measure curtains in our UK workrooms, with fullness options to suit specification requirements.

Fantastic at a very reasonable price.I took my time to choose the fabric to make sure I ordered the best option in the right colour. When I finally placed my order I was delighted with the speedy delivery and above all the quality of the product. This was the first time I sewed curtains using a wave heading and as I wanted to optimise the amount of incoming light, I opted for an asymetric distribution of the stacks and railroading of the fabric. Lots of calculations and checking but the result is very professional and impressive.0 people found this helpful

Great communication and customer service.Great service. I contacted them on the Thursday just to make sure I was ordering the right product. The online chat worked very well and I got all my answers.

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
