General SCIF perimeters include all walls that outline the SCIF confines, floors, ceilings, doors, windows and penetrations by ductwork, pipes, and conduit. This section describes recommended methods to meet the standards described within ICS 705-1 for SCIF perimeters. Perimeter wall construction specifications vary by the type of SCIF, location, use of SID, and discussion requirements. Closed storage that do not require discussion areas do not have any forced entry or acoustic requirements. Open storage facilities without SID require additional protection against forced and surreptitious entry. When an existing wall is constructed with substantial material (e.g., brick, concrete, cinderblock, etc.) equal to meet the perimeter wall construction standards, the existing wall may be utilized to satisfy the specification. Closed Storage, Secure Working Area (SWA), Continuous Operation, or Open Storage with SID - Use Wall A - Suggested Standard Acoustic Wall (see construction drawing for details). Three layers of inch-thick wallboard, one layer on the outside of the SCIF and ⅝ two on the inside of the SCIF provide adequate rigidity and acoustic protection (Sound Class 3). Wallboard shall be attached to 3 inch-wide metal studs or wooden 2 x 4 studs ⅝ placed a maximum of 24 inches on center. Continuous runners (same gauge as studs) for securing studs shall be anchored to the true floor and true ceiling structures. The interior two layers of wallboard be mounted so that the seams do not align (i.e., stagger joints). Acoustic fill shall be placed between the studs in a manner which prevents slippage. The top and bottom of each wall be sealed with an acoustic sealant where it meets the slab. Wall penetrations shall be treated and sealed with acoustic material. Entire wall assembly shall be finished and painted from true floor to true ceiling. Open Storage without SID -- Use Wall B - Suggested Wall for Expanded or Wall C - Suggested Wall for Plywood. Three layers of inch-thick wallboard, one layer on the outside of the SCIF and ⅝ two on the inside of the SCIF provide adequate rigidity and acoustic protection (Sound Class 3).
