KINETICS® KNC

Noise Control Curtains

Noise control curtain systems are custom engineered to your application for acoustic performance and structural integrity. A cost effective solution to reduce unwanted noise, noise control curtain systems are available as both barrier walls and complete enclosures. All systems are designed and manufactured to meet OSHA and customer requirements regarding noise reduction, maintenance access and ventilation to remove unwanted heat build-up. Options include view ports, ventilation silencers, acoustic louvers, and rigid roof panels.

Description

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

Noise control curtains are available from 0.50 to 2.50 PSF (2.5 to 12.5 kg/m2) surface weight. The systems are typically used for applications where accessibility, toughness, oil and chemical resistance, and an attractive appearance are required. Curtain systems can yield noise reduction of 12-15 dBA.

KNC-50C and 100C clearview curtains or windows are available.

KNC-50RB and 100RB are reinforced vinyl barriers.

KNC-50RBQ and 100RBQ have an aluminum-faced, quilted fiberglass absorber towards the noise source to block sound from escaping and to absorb sound that is reflected.

KNC-50BQQ and 100BQQ are vinyl barriers completely encased in quilted fiberglass absorber and are designed where additional absorption and Class A flame and smoke test requirements are needed.

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 KSD strip doors and clear vinyl windows are easily incorporated into curtain systems for visual and personnel access.

Application

Common applications are encountered in industrial and commercial facilities. OEM customers incorporate acoustical curtain systems in either roll form, die-cut or custom system formats. Curtain systems can be used as a partial barrier or complete enclosure around noise sources. Curtain panels are more versatile and economical than a rigid panel. The acoustical curtain systems can be designed for noise reduction up to 25 dBA dependent upon the noise source sound spectrum shape (low, mid, high frequency or a combination).

Attachment

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

Channel support systems for curtains are standard 1.625" x 1.625" (41 mm x 41 mm), 12-gauge rolled channel that can be floor-mounted or suspended. 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 non-movable curtains. Kinetics engineering can design structured steal support frames as needed.

Specification

Curtain systems shall consist of panels which meet the specifications and physical properties of the curtain material. Each panel shall be furnished with Velcro® self-adhering nylon closures along the entire length of each edge.

Support points at the top of each panel shall be reinforced at grommet locations not more than 12" (305 mm) apart. Support systems for curtains shall be 1.625" x 1.625" (41 mm x 41 mm) 12-gauge formed channel with associated hardware as designed by Kinetics Noise Control.

Complete system shall be Model KNC as man-ufactured by Kinetics Noise Control, Inc.
