Abstract: The edge sealed substrate layer composite panel comprises two transparent substrate layers (2, 2'), and a functional film-composite element, which is arranged between the transparent substrate layers, where an area expansion of the transparent substrate layer is greater than the functional film-composite element. A sealing means is extensively arranged along the edge surface of the functional film-composite element and provides an edge sealing of the substrate layer composite panel. The functional film-composite element consists of two laminating film layers. The edge sealed substrate layer composite panel comprises two transparent substrate layers (2, 2'), and a functional film-composite element, which is arranged between the transparent substrate layers, where an area expansion of the transparent substrate layer is greater than the functional film-composite element. A sealing means is extensively arranged along the edge surface of the functional film-composite element and provides an edge sealing of the substrate layer composite panel. The functional film-composite element consists of two laminating film layers between which a function film (3) is completely embedded so that the edge surface of the functional film-composite element directly passes on the sealing means for plant through which the laminating film layers are provided. The two transparent substrate layers are congruent and the functional film-composite element is arranged between both sides of the substrate panes. A split having a depth is provided between the substrate layers in which the sealing means is completely incorporated as an inner sealing means. The sealing means is completely arranged along the edge surface of the functional film-composite element and is additionally arranged along the edge surface of substrate layers and a sealing grip is provided on the edge of the substrate layer laminated panel. The inner sealing means is provided through a sealing cord or a sealing band equipped with adhesive surfaces made of elastomer material such as butyl and silicone, and a plastic material or a metallic material such as aluminum. The sealing grip is provided through a metal band flexibly to a wrap-around profile with adhesive surface turned to the substrate layer and laminated film (11), and seal coating layer or through an overmolding with a sprayable material such as thermoplastic elastomers. A barrier layer applied in a plasma chamber through sputtering and/or polysiloxane barrier layer surrounds the functional film of the functional film-composite element and/or an edge seal is arranged on an edge of the functional film of the functional film-composite element. A weather strip made of an elastomeric material such as rubber, and thermoplastic elastomer is arranged along an edge of the substrate layer and provides a spaced wrap-around sealing around the substrate layer and the functional film-composite element. An independent claim is included for a method for producing a functional film with a barrier layer for substrate layer laminated panel.
