Heavyweight Curtain Interlining Synthetic

This heavyweight poly curtain interlining (or bump) is used to add extra body and warmth to your curtains. This is a thick interlining fabric, particularly useful for door curtains, long curtains and is especially useful for adding extra insulation to draughty windows. Use heavyweight interlining for thermal lined curtains, and also to add a feeling of weight and luxury. This synthetic interlining is a blend of polyester and viscose, making it light and warm. The colour is off-white, which should not be visible in normal use. For maximum thermal properties in your curtains, use with our new Metallic Curtain Lining, which reflects heat back into the room. Suggested uses
  • Use interlining in door curtains, to keep your house cosy
  • Add to long curtains to add a luxurious feel
  • Use interlining to add weight to your curtains
  • Great for extra insulation for cold windows
Interlining for curtains is placed between the show fabric and the lining when the curtains are made.
