Panel Construction

insulated enclosure infastructure panelModular structures are all custom designed to fit the individual customers’ needs. Each panel consists of an interior and exterior metal pan with structural wood frame, steel rail and high density foam rail frame. These pans are separated by rigid foam-in-place self extinguishing urethane insulation which adheres to the interior of the pans providing increased structural strength. All panels have tongue and groove construction and a sealant gasket is applied to all joints forming an air-tight seal. Each panel is secured together using a state of the are cam locking fastener system that allows access to tight each panel while maintaining a smooth exterior and interior surface.
