Curtains serve a decorative function but may also improve the acoustics of a room and, if used as a door curtain (portiere), increase thermal comfort.

Curtains can be suspended on a rod or attached to a strip. The choice of the curtain rod and the way the curtains are draped strongly affects the style of the interior. In modern interiors, curtain rods or strips should be plain and made of high-quality materials. As for historical interiors, you can choose from a variety of curtain rods with decorative knobs and a range of accessories: sashes, decorative metal buckles, traditional and rigid valances, trimming tails and ropes.

To block out the sun, it is best to choose curtains made of thick, non-transparent or lined material. Lining gives every curtain a more elegant and refined look. An alternative solution is completely opaque blackout fabrics or dim-out fabrics, which block light only partially. The latter are softer than their blackout counterparts, so it is easier to drape and arrange them into truly decorative shapes.

In some cases (in hotels, restaurants, cinemas etc.), it is required to use specialist fabrics with flame retardant properties, improved acoustic parameters or other features.
