Texaa Velio acoustic curtain

Name: Texaa Velio acoustic curtain
Brand: Texaa

EPD availableWallFree-hanging

Description

The Velio acoustic curtain absorbs sound and, thanks to its non-woven core, also works as a blackout curtain. It is made in flat panels joined by zippers in the fabric color and runs on a rail, so it opens and closes easily by hand. Drawn in front of a window it calms light and sound and adds thermal comfort. Hung in the middle of a room it becomes a movable, sound-absorbing divider. More fullness means deeper pleats and more absorption.
