Sound Enclosure Product Details
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
