What is the difference between blackout and dimout fabric?

What are thermal curtains and how do they work?

Thermal curtains are designed to provide insulation and reduce heat loss through windows.

What is Curtain Fullness & What Fullness will my Curtains be?

What does curtain fullness mean and how much do I need? Curtain fullness refers to how much fabric is used compared to the width of your curtain track or pole. More fullness creates deeper pleats and a more luxurious finish when the curtains are closed. At Direct Fabrics we manufacture most made to measure curtains as standard using 2x the track width , also known as double fullness . This is the industry standard for pencil pleat and eyelet curtains, and means you do not need to calculate or choose fullness unless you want something different. We automatically allow for the correct amount of fabric and round up widths where needed to ensure the best finish. Certain heading styles, such as pinch pleat or wave, require more fabric due to how the pleats are formed, and are handled automatically based on the heading you select. For a visual explanation, examples and guidance on how fullness affects the appearance of your curtains, see our full guide on Understanding Curtain Fullness .
