Linings play a very important role in creating window coverings. The lining role is much more than for cosmetic purposes. They can act an insulator creating thermal curtains. They can also act as a shield from the light creating blackout curtains. And finally they can act as a sound barrier creating insulating curtains. Whatever your needs may be, lining will make the difference when selecting your window coverings.
Blackout curtains are created when blackout lining is used to line your drapery panels. You can opt for 100% blackout linings, or you can get a 50% dim out lining. Both linings will provide sufficient blockage of the sun. The 100% blackout will prevent all sun from shinning through your window. The 50% dim-out lining, also known as suede lining, will only dim the sunlight from your window. However, it will be more protection from the sun than traditional sateen or cotton linings. This will not only prevent sunlight from shining through your windows, it will also help protect your fabric from UV Rays. This is very important for finer fabrics, such as silk, which would completely rot from the sun within a matter of a year or two without proper lining.
Thermal curtains or insulated curtains are created when you add a very heavy interlining in between your curtain and your lining. A thick flannel interlining will help preserve the life of your drapery panels. They will also give them a plush full look. In addition to those wonder features, they will help block the heat and the cold in your windows. A heavy English bump interlining will keep noise as well as the heat in the summer and the cold air in the winter.
