- Enable the back of the drapery smooth and clean.
- Protects curtain fabric from harmful UV rays.
- Moderate noise insulation.
- Moderate sunlight protection.
- Reduce energy costs by insulating windows from heat loss in the cool months, and heat transfer through the summer months.
Note: Liners for curtains are typically not hemmed to the extreme bottom and sides.
To prevent unwanted light from sneaking in through any gaps, consider a puddled length (where the curtains extend beyond the floor) and a wider width (extending beyond the window frame on both sides)
