Noise Control Acoustical Curtain Systems Model KNC

Description

Kinetics Model KNC Noise Control Curtains are modular, reinforced limp mass vinyl panels or vinyl and quilted fiberglass composites designed to contain noise or to act as a movable barrier between noisy and quiet areas. Kinetics Noise Control curtains incorporate a self-supporting track which allows the curtain to open for access at virtually any point along the enclosure.

Kinetics curtains are available from 1/2 to 2-1/2 PSF (2.5 to 12.5 kg/m2) surface weight and provide an average increase in sound transmission loss of up to 29 decibels. The systems are typically used for applications where accessibility, toughness, oil and chemical resistance, and an attractive appearance are required.

Each acoustic curtain panel is furnished with Velcro self-adhering nylon closures along the entire length of each edge and grommets along the top.

Kinetics Models KNC-50C and 100C Clearview Curtains or windows are available where monitoring of equipment is required. Models KNC-50RB and 100RB are reinforced vinyl barriers. Models KNC- 50RBQ and 100RBQ have an aluminum-faced, quilted fiberglass absorber towards the noise source to both block the sound from escaping and to absorb the sound that is reflected. Models KNC-50BQQ and 100BQQ are vinyl barriers completely encased with the quilted fiberglass absorber on both sides. Class A flammability ratings per ASTM-E-84.

Channel support systems for curtains are 1-5/8" x 1- 5/8" (41 mm x 41 mm) 12-gauge rolled channel that can be floormounted or suspended from the ceiling. Curtain panels can be attached to the support system by trolly assemblies for movable curtains or fixed to the support system by mechanical fasteners for a non-movable curtain. Standard BQQ curtain panels are 48" (1219 mm) wide and standard RBQ curtain panels are 54" (1372 mm) wide. BQQ and RBQ are available in lengths of up to 20’ (6096 mm). Kinetics Model KSD strip doors and clear vinyl windows are easily incorporated into Model KNC curtain systems for visual and personnel access.

Applications

Model KNC Noise Control Curtains can be used as a partial or complete enclosure around noise sources. Acoustic curtains are especially useful for enclosures around industrial equipment since the enclosure is more versatile and economical than a rigid enclosure. Typical applications include barriers/enclosures around:
