DESIGN CHALLENGE

A common design challenge with open-plan offices is poor acoustics. It is also a major complaint in interior spaces as diverse as hotels, restaurants and healthcare facilities. Research shows that poor acoustics can negatively affect productivity, learning and healing. Drapery is a common solution when it comes to improving the acoustics in a space, however opaque styles with a high NRC do not offer light transmission or transparency. Typical sheers are wholly ineffective at absorbing sound. Designers often want acoustical absorption combined with visual transparency.

CARNEGIE'S DESIGN SOLUTION

Carnegie’s acoustically absorbent sheers use innovative yarn and weaving technology allowing designers to achieve both the transparency of a typical sheer with significant NRC ratings between (0.4-0.7) when draped, delivering effective noise reduction
100+ Acoustical Sheer Choices

Partnering with Creation Baumann of Switzerland, these draperies are woven with specially engineered technical Trevira CS polyester that absorbs a large amount of sound waves within a space. Available in more than 100 choices, they all boast a soft hand and beautiful drape. Fully vetted through third party certifiers, these sheers achieved approximately 40% sound reduction when hung flat and 50-65% sound reduction when draped: that’s over 10 times more effective than a regular sheer. • Acoustically Absorbent
• 3rd Party Tested
• Trevira CS content
• Wide width (118")
• Offered in metallic/tech looks or matte classic feel



1. Fabric must be acoustically absorbent. Acoustically absorbent fabrics have an NRC between .45 - 1 2. Fabric must pass NFPA 701 3. Fabric should be woven with Trevira CS polyester



NRC (Noise Reduction Coefficient)

Noise Reduction Coefficient rates the amount of sound that an material absorbs. Like a sponge absorbs water, an acoustic product absorbs sound and the NRC tells us just how much sound those products absorb. For effective acoustical absorbency, draperies should have an NRC between .45 - 1.

NFPA 701

This test measures the flammability of a fabric when it is exposed to specific sources of ignition.NFPA 701 testing measures the ignition resistance of a fabric after it is exposed to a flame for 12 seconds. The flame, char length, and flaming residue are recorded. Fabric certified as flame retardant is certified to have been tested and passed the NFPA 701 test, a requirement for hanging textiles such as draperies in all commercial spaces




With open workspaces and common spaces, the need for acoustics are not restricted to the perimeter of the room. Where to use Acoustical Sheer Draperies
• Along the window wall (Restaurants, dining areas to absorb ambient sound)
• Glass conference rooms (provide some privacy, let light in AND improve acoustics)
• As a space divider (in lieu of walls, using light, transparent draperies to create spaces as needed)
