Interlined curtains are the ultimate in luxury and style for any window. We specialise in hand made bespoke interlined curtains, which have soft, full folds, producing beautiful columns of fabric. Interlined curtains have an invisible layer of fabric sandwiched between the visible parts of your curtains – the decorative main fabric that faces into your room and the lining that faces out the window. Typically made of cotton, interlining has a similar texture to cotton wool or a flannel blanket.
Properties of Interlined curtains
In these days of energy efficiency you may not be aware of something that is primarily used to enhance window treatments but also adds to the insulating properties. Similar in feel to a flannel blanket, interlining is an extra layer of fabric, usually cotton, placed between the main fabric and the lining. There are many beautiful fabrics that on their own would produce curtains that are thin and lifeless, but by adding a layer of interlining the ‘feel’ of the fabric changes dramatically and the curtains become thick and sumptuous. This extra layer however not only adds to the handle of the fabric but because of the increases in the thickness it therefore makes it more insulating.
What are the different types of interlining?
There are three different types of interlining available, two made from Cotton (Bump and Domett) and the third from Polyester (Saril).
Bump Interlined curtains
This is the thickest interlining and is loosely woven fabric made from around 80% cotton and 20% mixed synthetic fibres. It should be used pre-shrunk as the high cotton content has a tendency to shrink in the damp atmosphere around windows. Bump produces the best looking interlined curtains as it drapes beautifully and is especially suitable for silk, however it is also the hardest to work with as the loose weave results in an unstable fabric that moves and sheds fibres easily. The typical weight of bump is 400g/m 2 with a thickness of 0.5mm (1/4″)
Domett Interlined curtains
This interlining is a heavily brushed 100% cotton twill fabric slightly thinner than Bump and as you can see from the top picture it is available in different weights. It is relatively easy to work with but that does mean that the drape isn’t as good as Bump. Most of the interlined curtains I have made have used Domett as it works with many different types of fabrics. The lightweight Domett is particularly suitable for blinds and other areas where the fabric will be pleated such as swags & tails. Domett weight can be from 160g/m 2 to 300g/m 2 with a thickness of a few millimetres.
Saril interlined curtains
Saril is a synthetic cheaper alternative to the cotton interlinings however as it doesn’t have the drape qualities, and I wouldn’t recommend using it unless necessary. It is not a woven fabric but stitch bonded- the fibres are joined together with rows of small stitches, and comes in similar weights to the cotton alternatives. The major advantage of Saril over Bump or Domett is that it doesn’t shrink so if interlining is required when there is a lot of moisture (kitchen, bathroom or damp house) you would choose Saril interlined curtains.
