Expectation setting: Bolton Twill is described as a dimout face fabric that helps reduce light entry. It is not blackout as standard. If you require blackout performance, select a blackout lining option when specifying your curtains.
Top tip: Any of our curtains lined with our blackout lining are thermally certified to reduce heat loss by 30% over a double glazed window.
Why specify Bolton Twill stage curtains
Bolton Twill is a traditional twill weave specified for stage curtains across schools, theatres and community venues. The diagonal weave is chosen for practical day-to-day use, helping to disguise surface dust and general handling marks.
These curtains are supplied as NDFR (non-durable flame retardant) and certified to BS5867 Part 2 Type B. If the fabric is wetted in any way, it must be retreated to maintain flame retardant performance.
If you need documentation for compliance or project files, certificates and supporting information are available in the Specs tab. Cleaning and care guidance is also provided there for reference.
Where this fits in our range
Choose Bolton Twill when you need a traditional stage-curtain look in a practical black twill with BS5867 Part 2 Type B certification. If your priority is maximum blackout, specify a blackout lining option or select a dedicated blackout face fabric elsewhere in our range.
Best suited for
- Stage curtains for schools, theatres and performance areas
- Village halls and community venues needing a hard-wearing black curtain
- Projects requiring BS5867 Part 2 Type B documentation (see specs)
Who uses Bolton Twill stage curtains
Commonly specified for education and community venues including schools, village halls, and theatres. Suitable for commercial environments where a flame retardant stage curtain is required and dry cleaning is practical for ongoing maintenance.
As these curtains are made to measure, they can be configured for typical stage headings (including pencil pleat, webbing to snap hooks, and tie tops), and lined options can be selected depending on the level of light control required.

Headings Options for Stage Curtains:
Pencil Pleat:
Pencil pleat is the traditional style of curtain heading that is a used in most windows and gives a lovely finish. You have the flexibility from the stitched in curtain tape which allows you to alter the height above your track and pole.
Webbing to snap hooks:
Webbing to Snap Hooks clips sewn into the heading tape that then clip straight into a stage track. Not all tracks are suitable for this. Please send over images of your current track if you need any help.

Tie tops:
Tie tops can be tied onto a pole or batten, great for backdrops and for curtains that need to be portable around different spaces.

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 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
SAVE TIME - Send your project requirements, large or small. Sample Lists etc
