Achievable Noise Reduction
NOISEBLOCK™ acoustic enclosures offer typical noise reductions of 20-35 dBA. Special custom
systems incorporating heavier (thicker gage) panel shell, thicker panels or an enclosure within an
enclosure are available to achieve higher levels of noise reduction.
Type STL acoustic panels are fabricated of various thicknesses and materials depending
on the level of noise control required for a particular application. Standard KINETICS
NOISEBLOCK™ type STL panels are fabricated with an outer solid shell of 18 gage and inner
perforated shell of 22 gage steel. Panels are stiffened with 18 gage internal channels and edge
rails. The acoustic grade fill is 2.5 to 6 pcf long strand fiberglass or mineral wool, depending on
the application, are inert, mildew resistant, vermin proof and incombustible. Standard panels are 4"
thick, but optional 2" and 6" panels are available to meet special requirements.
Type HTL acoustic panels are designed for applications where a higher transmission loss is
required. Standard KINETICS type HTL panels are fabricated with an outer solid shell of 16
gage and inner perforated shell of 22 gage steel with a high mass septum added for increased
acoustic performance. Panels are stiffened with 18 gage internal channels and edge rails. The
acoustic grade fill is 2.5 to 6 pcf long strand fiberglass or mineral wool depending on the application
and are inert, mildew resistant, vermin proof and incombustible. Panels are available in 4" or 6" thickness.
Outer and inner shell materials are available in standard galvanized steel, Type G90, mill
phosphatized (satin) finish galvanized steel (readily paintable), stainless steel, Types 304
and 316, aluminum and aluminized steel. Standard material gages for solid outer shell
are 18 ga. and 16 ga., perforated (23% open area) inner shell is 22 gage. Septum panels and
panels with solid outer and inner shells are available. Factory applied powder-coat finish is
available as an additional option.
All internal sound absorbing media used in NOISEBLOCK™ panels meet the requirements
of NFPA-90A and surface burning characteristics per ASTM E84, with maximum flame spread
rating of 25 and smoke developed rating of 50. Other media are available offering more
stringent flame spread index and smoke developed index. The media is available both unlined,
lined or bagged using a specialized film or cloth barrier and acoustic spacer. The insulation is under
compression so as not to allow settling of acoustic media within the panel.
Standard Panel Dimensions
NOISEBLOCK™ panels are available in standard designated widths of 21.625" and 45.625" and lengths
up to 144". Other widths and lengths are available by request.
The insulation materials used in NOISEBLOCK™ panels at 75˚F have maximum thermal conductance
values of 0.06 BTU/hr-ft2-˚F (4" thick) and 0.12 BTU/hr-ft2-˚F (2 inch thick). Thermal resistance values are
R17 (4" thick) and R8 (2" thick). Other insulation materials yielding higher thermal performance values

Silenced Ventilation Systems
Kinetics Noise Control ensures the enclosed equipment or process is properly ventilated as to prevent overheating
by choosing from our expansive product line of circular (VCS), rectangular straight (VRS) and elbow (VES)
absorptive or reactive silencers and fixed-blade acoustic louvers (KCAL/KCPL/KCAC). All are backed by independent testing per
ASTM E477 and/or ASTM E90 in NVLAP accredited laboratories.
Observation windows are available as doublepane, wire reinforced, or tempered safety glass. The windows are held in place
with a flexible acoustic, airtight seal and separated by an airspace of the same thickness as the NOISEBLOCK™ panel. Depending
on window size it can be factory installed or shipped and field installed. High STC rated windows are available
were maximum noise control is required.
A complete line of single and double leaf NOISEBLOCK™ access doors are available in various sizes and can be incorporated to
meet a variety of needs such as personnel and machinery access. Single and double leaf access doors are available with industrial grade
strap hinges (swing right/left, in/out) and panic/passage hardware (keyed locks or sliding hardware are available as an option). The maximum
single leaf door size is 48" wide x 96" high and the maximum double leaf door size is 144" wide x 144" high. Door thicknesses match adjacent
panel thickness, construction, and acoustic performace.
Pressurized plenum single leaf doors are available in various sizes and have acoustic edge and bottom seals, doors are factory
pre-hung, insulated and equiped with 2 or 3 strap hinges with Ventlok latches. (zinc and aluminum non-corrosive alloy). Double-pane, wire
reinforced view ports are an available option.
NOISEBLOCK™ removable access panels for walls and roofs can be located and sized as required for easy access to interior equipment
for maintenance, service, or repair. The construction of removable panels is the same as the surrounding panels. Depending on the size
and frequency of use, removable panels incorporate Ventlock latches or bolted connections. Roof access panels for outdoor applications can
be designed for sloped roofs or can incorporate a rasied curb for flat roofs. Lifting lugs and special flashing are included as required.
