ACOUSTIC PERFORMANCE TIP

Before selecting the type of partition you need, it's important to know how the area to be divided will be used. That will tell you the configuration and how much sound control is needed.

The acoustical performance of the partitions, however, will only be as good as the room in which they are installed. For optimum performance, the room must include flat, level floors, a level track suspended from a non-sagging structure, a sealed and insulated plenum barrier, plumb end walls and indirect HVAC ducts. The American society for Testing and Materials standard practice for Architectural Application and Installation of Operable Partitions E557-E90 describes these requirements in depth and is included in the booklet. Sound Control Performance of Operable Partitions. This booklet and Hufcor's brochure, Understanding the Acoustics of Operable Walls, are available free of charge through your local distributor.

How good is an STC rating?

Use the following chart for a rough idea what the various STC levels mean. Note this is a very rough guide.

STC Privacy Afforded
25 Normal speech easily understood
30 Normal speech audible, but unintelligible
35 Loud speech understood
40 Loud speech audible, but unintelligible
45 Loud speech barely audible
50 Shouting barely audible
55 Shouting not audible

SEAL FORCE

Continuous seal force is required for maximum sound control. Hufcor's quick-set mechanical seals exert upward and downward force to tightly seal the panel. Full continuous pressure is achieved by a simple turn of the removable waist-high activator. Because the seals are retractable, they don't wear out or leave rub marks on ceilings or floors. And, Hufcor's And, Hufcor's lever closure panel exerts more than 250 lbs. of force for tight panel-to-panel seal.
