    system U-Value

Applicable to swinging door systems (with or without glazing inserts), with or without sidelites/transoms, intended for exterior installation in commercial or residential buildings. This includes steel doors (insulated and uninsulated), composite doors, wood doors, and stile-and-rail doors. Specifies both testing and calculation methods for establishing the following door thermal properties for both residential and commercial applications: Overall heat transmission coefficient (U-value) Solar heat gain coefficient (F)
