Guidance on Curtain Linings

Lining is a fabric sewn to the back of drapery or shades, typically attached along the sides while leaving the bottom unsewn.

Its benefits include enhanced sun protection, improved insulation, and better light control. Lining can provide a polished finish to curtains, making them softer, blocking out sunlight, reducing noise, and insulating against heat and cold.

This helps to minimize energy loss through windows.

Unlined

  • Adding a lining is usually unnecessary unless superior light-blocking is needed.
  • Light-blocking capability varies with fabric color; lighter colors block less light.
  • For white curtains, adding a lining is recommended for improved light-blocking performance.

90%-95% Blackout Lining

  • Made from 100% triple-weave polyester with a 260 gsm weight and off-white finish
  • Offers moderate protection from sunlight damage
  • Crease, water, and stain resistant
  • Reduces energy costs by insulating against heat loss in cooler months and heat transfer in summer
  • Provides moderate noise insulation

100% Blackout Lining

  • Microfiber coated with white foam, 120 gsm weight and grayish white finish
  • Do not machine wash; wipe clean due to coating
  • Provides moderate noise insulation and protection from sunlight damage
  • Crease, water, and stain resistant
  • Significant thermal insulation reduces energy costs by minimizing heat loss in cooler months and heat transfer in summer
