Curtains are more than just fabric hung over windows; they’re a crucial element of interior design that can transform a room’s ambiance. While the outer fabric of curtains often gets the spotlight, the lining fabric plays an equally important role in functionality and aesthetics. When making your?custom curtains, there is one question you should know: do all curtains need linings?
Understanding Curtain Lining Fabrics
Curtain lining fabrics serve several purposes, from enhancing the appearance of curtains to providing practical benefits such as insulation and light control. Here are some common types of curtain lining fabrics:
- Polyester/Cotton Blend: This versatile lining fabric combines the durability of polyester with the breathability of cotton. It’s commonly used for a wide range of curtains due to its affordability and ease of maintenance.

- 100% Blackout Lining: Ideal for bedrooms, nurseries, and media rooms where complete darkness is desired, 100% blackout lining fabrics block out sunlight entirely, ensuring optimal conditions for sleep, relaxation, or immersive movie-watching experiences. They also provide excellent thermal insulation, helping to regulate room temperature and reduce energy costs.
The appearance of the 100% blackout lining looks the same as that of the common lining, but they have an extra layer of blackout fabric in the middle, which enables it to 100% block out light. - Thermal Lining: Designed to improve energy efficiency, thermal lining fabrics trap heat during colder months and block out excess heat during summer, keeping your home comfortable year-round. They can help reduce energy bills by minimizing the need for heating or cooling.
- Interlining: Interlining is an additional layer of fabric placed between the face fabric and the lining. It adds fullness and body to curtains, giving them a luxurious appearance. Interlining also enhances insulation and can improve the drape of the curtains.
- Cotton Sateen Lining: With a smooth, lustrous finish, cotton sateen lining adds a touch of elegance to curtains. It offers moderate light filtration and improves the drape of lightweight fabrics.
- Sheer Lining: Sheer lining fabrics are lightweight and translucent, allowing diffused light to enter the room while providing privacy. They’re often used in conjunction with?sheer?or lightweight curtain fabrics to maintain an airy feel.

Do All Curtains Need Linings?
While the decision to use curtain linings ultimately depends on personal preference and specific requirements, there are several benefits to consider:
- Enhanced Aesthetics: Lined curtains have a polished, finished look compared to unlined ones. The lining adds weight and substance to the curtains, creating a more luxurious appearance.
- Improved Insulation: Lining fabrics, especially thermal and blackout varieties, help regulate temperature by preventing heat loss in winter and heat gain in summer. This can lead to energy savings and a more comfortable living environment.
- Protection for Face Fabric: Lining fabrics provide a protective barrier for the face fabric, shielding it from fading, dust, and wear over time. This prolongs the lifespan of the curtains and preserves their original color and texture.
- Light Control and Privacy: Depending on the type of lining chosen, curtains can offer varying degrees of light filtration and privacy. Blackout and thermal linings block out light effectively, while sheer linings allow diffused light to enter while maintaining privacy.
