Why Thermal Lining Fabric Makes a Difference
Drafty windows can undo even the prettiest drapes. Thermal lining fabric adds an insulating layer behind your curtains, helping hold warmth in during winter and keep summer heat out. It's one of the simplest upgrades you can sew into new window treatments or add to the ones you already have.
What to Look For
Backing and Weight
Most insulated curtain lining has a coated or foam-backed side that faces the window. Heavier coatings generally block more drafts and light, while lighter versions drape more softly and suit sheer or delicate face fabrics.
Light Control
If you want darkness as well as warmth, choose a blackout thermal lining. It's a favorite for bedrooms, nurseries, and media rooms.
Color and Handling
White and ivory linings give a clean, uniform look from the street. Also consider how easily the drapery lining fabric cuts, presses, and stitches on a home sewing machine.
Popular Uses
- Lining new drapes, valances, and Roman shades
- Making a removable thermal curtain liner for existing panels
- Sewing energy-saving curtain panels for patio doors and sliders
