It is vital to the long term success of any structure to employ an impenetrable building enclosure.  The definition of a building enclosure or a building envelope: It is the physical separator between the conditioned and unconditioned environment of a building.  This includes the resistance to air, water, heat, light, and noise transfer.  There are three basic pieces to a building envelope: weather barrier, air barrier, and thermal barrier.  Engineered Systems is proud to represent key manufacturers that can assemble a building design that will stand the test of time and keep the building safe from the elements.
