Texaa Velio acoustic blinds

Name: Texaa Velio acoustic blinds
Brand: Texaa

WallFree-hanging

Description

Velio acoustic blinds are vertical slat blinds. A patented hanger plate hidden in the top hem replaces bottom weights and sits close to the rail, so little light passes above the slats. On the optional rail they turn and gather by cord. In front of glazing the blinds absorb sound, filter daylight and reflect part of the solar heat. Inside a room they mark out zones without closing them off, for example a quiet listening corner in a media library.
