ACOUSTIC CURTAINS

A better sounding space.
By design.

Control sound reflections with a curtain system specified for the room, the fabric and the way it is installed.

ABSORPTION, WITH EVIDENCE

The fabric is only
part of the story.

Acoustic curtains introduce absorbent surfaces that can help control reflections and reverberation. The result depends on frequency, coverage, fullness and the space behind the fabric.

Sound absorption and sound insulation are different. An absorption rating does not describe how much sound is prevented from travelling to the next room.

PUBLISHED CONFIGURATION DATA

Same fabric.
Different construction.

Wool Serge 800 demonstrates why mounting conditions belong beside every performance figure.

UNDERSTAND THE BUILD-UP

Space behind.
Fullness in front.

100% fullness means twice the flat fabric width relative to covered track width, before making allowances. It is a construction ratio—not a 100% absorption claim.

A wall cavity is the space between the curtain and the wall. Use the matching tested configuration when selecting performance data.
