Lockdown is the acoustical ceiling system for supervised areas of minimum and medium security correctional facilities.
Lockdown's heavy duty standard module, exposed grid construction makes possible the cost effective integration of acoustics,
lighting, and mechanical systems in the correctional environment. Cel∙Line is a cost effective high security acoustical
plank system ideal for use in cells, holding areas, and medium and maximum security day rooms.
Perforated Lockdown and Cel∙Line panels, topped with acoustical pads, provide the ideal acoustical media for
correctional facilities. The Lockdown and Cel∙Line systems achieve an N.R.C. (Noise Reduction Coefficient) of
up to .95, substantially reducing overall noise levels. Sound reverberation time can be reduced to below 1 second in most day
room configurations utilizing Lockdown or Cel∙Line ceilings. In areas where sound transmission is of concern,
mineral fiber acoustical panels or steel backer sheets may be substituted for fiberglass acoustical pads, enabling the
Lockdown or Cel∙Line system to achieve an S.T.C. (Sound Transmission Coefficient) in the range of up to 40 to 44.
Lockdown's industry standard 2'x2' and 2'x4' grid modules effectively accommodate the electrical, mechanical, and
security systems of today's correctional facilities. The Lockdown grid system accepts economical, easy to install Type
"G" recessed lay in security lighting fixtures and HVAC grilles. The installation of the Lockdown system creates a tamper
resistant plenum space allowing for efficient installation of mechanical and electrical systems.
Cel∙Line's 12" or 24" wide plank modules integrate with Type "F" 12" wide or 24" wide recessed security light fixtures
available from several leading manufacturers. If single source responsibility is a design requirement, consider using one of
Gordon's Cellite Security Lighting Fixtures with the Cel∙Line system or our Locklite Security Lighting Fixtures with the
Lockdown Ceiling system. Both fixture lines have a wide array of lenses, ballast's, housing gauges, and accessories
to achieve your design requirements.
The Lockdown system is constructed using rugged panels of 18 gauge steel or .040 aluminum for high humidity areas, extra heavy
duty steel grid components, and vertical steel compression members. Lockdown's panel design provides a continuous and secure
positive lock between the panel and the grid system without the use of clips or fasteners. When professionally installed in
accordance with the system details, Lockdown provides a rigid, tamper and abuse resistant ceiling system that serves as a visual
concealment barrier for supervised correctional interiors.
The Cel∙Line acoustical plank ceiling system is recommended for inmate rooms and other unsupervised areas where higher levels of
security acoustical performance are required. Cel∙Line's 12, 14, 16 or 18 gauge stainless steel or aluminum planks are ship-lapped and
side stitched to provide a continuous metal barrier. The Cel∙Line planks are then secured to matching steel support angles and tees
with Torx security fasteners, or steel rivets. The Cel∙Line system may also be directly mounted to the tops of solid filled ceiling
height masonry partitions through the use of concealed channels, thus creating an uninterrupted plenum while delivering savings in
Lockdown and Cel∙Line security screwed access panels can be located anywhere within the field of the system, allowing for controlled
access to mechanical and electrical items in the enclosed plenum. Access panels are provided at a minimal up-charge and may be
installed at any time up to final completion of the ceiling. System compatible 2'x2' hinged, downward-opening, locking access doors
are available for Lockdown and Cel∙Line at additional cost for items requiring repeated access.
Lockdown and Cel∙Line systems may be used in all of the various buildings throughout the correctional facility. The tough 18 gauge
steel Lockdown system is a specifier's favorite for lowering noise levels in day rooms, mezzanine walkways, and areas of assembly.
Lockdown is also often utilized in health, intake, administrative, and vocational buildings providing a combination of acoustics,
plenum concealment, economy, and accommodation of mechanical and electrical systems. Cel∙Line planks provide a combination of
security and acoustics for cells, holding areas, and medium and maximum security day rooms.
An .040" aluminum Lockdown system or a 16 gauge stainless steel Cel∙Line system is recommended for food service areas, showers and
other spaces where cleanliness, moisture resistance, security and acoustics are all of concern.
Lockdown and Cel∙Line install for a fraction of the cost of comparable acoustical metal decks and snap-in metal pan systems for
security facilities. Furthermore, costs for mechanical and electrical systems are reduced because of Lockdown's standard grid
modules and secure plenum.
The development of the Lockdown and Cel∙Line systems have had a direct and significant impact on today's cost of correctional
construction. The availability of a secure and economical suspended ceiling system has helped to allow correctional architects
and engineers to greatly expand the use of pre-fabricated metal buildings and other applications of steel construction in
correctional buildings that have historically required concrete and masonry construction.
Gordon, Inc. is the industry leader in the design and manufacture of specialty metal architectural, acoustical, and security
interior systems for commercial, industrial, and institutional applications, including correctional facilities. Lockdown,
Cel∙Line, and Cel∙Lock systems have been utilized successfully in over 6 million square feet of ceiling and wall systems at more
than 480 correctional facilities in 48 states.
