Lining options
Click to expand
All lining options from Direct Fabrics are flame retardant certified to BS5867 and can be used in commercial environments.
Unlined
A lower-cost option. If your fabric is dimout or blackout, you still get strong shading: dimout is typically 90%+ light reduction and 3-pass blackout is designed for full blackout. Final performance depends on fitting and where the track is positioned, as light can leak around the edges.
Standard polyester FR lining
A cost-effective way to add fullness and improve drape. Polyester FR lining is inherently flame retardant and is suitable for regular use. It adds extra shade behind decorative fabrics and is often chosen to give dimout and blackout fabrics a more luxurious handle.
3 pass blackout lining (FR)
The Direct Fabrics go-to lining for maximum light control. The 3-pass coating is hard wearing, adds a thermal benefit, and improves drape. Certified to BS5867 Part 2B for commercial environments. Edge leakage still depends on fitting.
Duo blackout lining with fleece (FR)
A heavy, premium option combining fleece with a blackout lining for extra body and a more substantial hang. The fleece layer can also help with echo reduction, making it a strong choice where you want improved room acoustics as well as blackout.

Absolutely Incredible!The reviews are what lead us to Direct Fabrics and they absolutely lived up to our expectations. From the get go Connie made the utmost effort to understand what we were looking for and provided so much knowledge to help with our decision. The window we were buying for is abnormally large for a domestic request at 4 metres wide, but Connie assured us throughout the process and made sure we were installing a track that could support the weight of the curtains. At no point did we feel like we were being rushed or pressured into something, just always there to answer any remaining questions we may have had, and Connie worked with us on fulfilling an additional request we had for the curtains' construction with no issues. We asked for a few more colour samples after deciding on the texture of fabric we liked, and this was no problem with the team. Connie even independently looked into an additional third party product we had mentioned being interested in getting further down the line, and gave her suggestions on what we'd likely need to consider based on this. When the curtains turned up (absolutely on schedule as advised), they were well packaged and they're stunning quality. Everything is as we wanted, and the workmanship is incredible. They hang beautifully and are the perfect fullness for our window so we had no worry of light gaps and things not meeting well in the middle (we went with ceiling mounted wave curtains). We also got a pair of matching cushion covers to tie the room together nicely, and they're made beautifully too. We rave about our curtains to anyone who will listen, from both a quality and customer service perspective, and will absolutely be returning when we work through the rest of our renovation. Thank you Connie and Team!0 people found this helpful

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

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
