Homeland Security Training Institute

On a typical metal panel building, the metal stud comes all the way out to the molding and therefore breaks the insulation. This interruption causes a continuous thermal break that allows more hot and cold transfer through the building’s envelope.
The College of DuPage’s Homeland Security Training Institute[1] uses a more thermally efficient Midland, Mich.-based
Dow Building Solutions’[2] THERMAX wall system[3] (2-inch aluminum-faced polyisocyanurate attached to 16-gauge cold-formed steel studs with 1.5 inches of Dow THERMAX spray foam insulation). The fastener, designed by Larson Engineering[4], Naperville, Ill., goes through the insulation and into the structural metal studs directly behind it. The screw acts as a cantilever as it goes out to capture the metal panel system that is 2.5 inches away from it.
The fastener choice allowed the design team to remove Z girts, resulting in continuous insulation and reduced thermal transfer. The enclosure features a combination of Santa Monica, Calif.-based Oldcastle BuildingEnvelope[5]‘s Vistawall curtainwall system with Auburn Hills, Mich.-based Guardian Industries Corp.[6]‘s low-E glazing and Cedar Rapids, Iowa-based
Metal Design Systems Inc.[7]‘s aluminum panels over a Dow THERMAX system. Using the THERMAX system also simplified design and streamlined construction.
Legat Architects Inc.[8], Chicago, was the architect of record for the Homeland Security Training Institute at the College of DuPage in Glen Ellyn, Ill. The 66,000-square-foot center is the first of its kind in the Midwest. The facility prepares multi-jurisdictional emergency personnel to respond to international and domestic terrorist acts as well as man-made and natural disasters.
