Unique Construction Features
Louvered Penthouse Style
• Hinged Cover - All sizes feature an
aluminum cover which may be hinged to
provide quick access to the motor and
drive assembly. Covers are fastened down
with a quick release hood latch.
• Large Interior Dimensions - All sizes allow
complete accessibility from above. Interior
dimensions offer clearance for inspection,
cleaning, or maintenance of the motor,
wheel, belt(s), and drives.
• Strength & Weather Resistant - Each unit
features storm resistant aluminum louver
blades with mitered corners. For decades,
our storm resistant blades have proven
highly effective. Each sturdy extruded
aluminum louver blade has a material
thickness of 0.080 inches.
Greenheck’s louvered
penthouse hoods feature
heavy gauge extruded
aluminum louvers
with mitered corners
for a clean, finished
appearance and weather
resistant construction.
The interior vertical edge of the curb cap
forms the throat and weathershield. Each
corner is also shielded to prevent leakage.
Penthouses are available in aluminum for
lasting durability and appearance.
Fabra Hood Style
• Hinged Hood - All sizes feature a hood
which may be hinged to provide quick
access to the motor and drive assembly.
Access may be gained by simply removing
two of the four hood fasteners or all
fasteners for complete removal.
• Large Interior Dimensions - All sizes allow
complete accessibility. Interior dimensions
offer clearance for inspection, cleaning, or
maintenance of the motor, wheel, belt(s),
and drives.
• Strength & Weather Resistance - The
hood is designed with arched panels
manufactured of heavy gauge, precision roll
formed steel with interlocking edges. Each
interlocking rib creates a tight, weather
resistant seal. Heavy gauge steel support
members provide structural strength. The
first hood was put into service over 30
years ago.
Greenheck’s interlocking rib design combines
four material thicknesses with I-beam design
principles producing a hood far superior
in strength to
conventional
designs (an
important feature
in high wind
and snow load
regions).
Formed channels
adjacent to the ribs provide water drainage to
ensure weather tightness.
Hoods are available in galvanized steel,
painted steel, or aluminum construction.
