Security Ceiling System

We furnish and install security ceilings in prisons, jails, juvenile facilities and detention centers worldwide. The acoustical metal security ceiling systems meet the full range of security ceiling requirements, from supervised areas of minimum and medium security facilities through in-cell use in maximum security detention applications. They also address the growing need to control noise in the detention setting, which creates not only a poor living environment for inmates, but also a stressful and unsafe working environment for correctional peace officers working in the detention facility.


• SecureDek is a low maintenance acoustical security ceiling system for supervised minimum and medium security areas in detention facilities. It is composed of 18 gauge galvanized perforated steel panels, 2′ x 2′ or 2′ x 4′. Its panels securely snap into a heavy-duty steel grid with vertical steel compression struts, cutting installation time. Panels are filled with a poly-wrapped fiberglass acoustical blanket to provide high sound absorption values. SecureDek specifications and test results are available as pdf files.

• BarrierDek provides an effective security barrier combined with excellent acoustics. The interlocking, single layer panels provide great resistance to passage or attack in applications such as lobbies and corridors, detention dayroom ceilings, holding areas, inmate cells, hospital secure areas, museums, pharmacies, gymnasiums, and burglar-vulnerable areas. The factory-finished, powder-coated panels are constructed of (A40) galvannealed steel; the panels slip into place and are interlocked together, supported by perimeter and “T” angles. No supplemental screw fastening is required, speeding installation time. BarrierDek specifications and test results are available as pdf files. Click here to go to our Resources page.

• TrussDek, a metal plank ceiling system that provides a maximum security barrier combined with excellent acoustics, is the most secure ceiling system available today for detention facilities or any high security application. Double-layer panels combined with a TrussCore center provide superior resistance to passage or attack in applications such as inmate cells, holding areas, detention dayroom ceilings, security corridors, soffit enclosures, and wall separators. The prime-coated panels slip into place and are welded together to provide a secure environment. The shiplap design makes installation quick and easy while preventing the concealment of contraband. The all-steel construction allows placement of accessories and utilities where they are needed, eliminating the need to frame around penetrations. They are supported by perimeter and “T” angles.
