Manufacturing a blackout involves coating a fabric with layers, or ‘passes’, of aerocellular acrylic foam. A 2-pass blackout is produced by applying two layers of foam to the fabric, while a 3-pass blackout will receive 3 layers of foam.
A denser fabric can be used between two fabrics or as a lining to improve room insulation, noise absorption and treatment shape.
COATING A DECORATIVE FABRIC
A blackout coating can be added to the back of a traditional fabric. This process is identical to 2-pass goods. This process ensures less light leakage through the fabric.
A semi-translucent fabric used to provide stability to treatments where blackout is not required. This process is commonly used in public area applications for roman shades and stationary panels to ensure a finished look.
