METHOD OF MANUFACTURING A SAFE, FREE OF OPTICAL SISTORSION COMPOUND GLAZING PANELS, APPLICATION OF SPECIAL CARRIER FILM FOR MAKING SUCH PANELS AND CARRIER FILMS IN PARTICULARY THOSE SUITABLE FOR USE IN THAT METHOD AND/OR APPLICATION
The invention relates to a method for producing a laminated glass pane free of optical obstruction, caused by warping, in reflected and transmitted light. The laminated glass pane comprises a first pane of glass, a second pane of glass and a multilayer spacer layer comprising a first composite film, a biaxially-stretched, thermoplastic carrier film provided with a thin layer system, and a second composite film. A carrier film provided with the thin layer system is mounted on the first composite film and has a thickness of from 30 to 70 mum and a degree of heat shringage of from 0.3 to 0.8%, measured after a heat treatment of 20 seconds at 120° C., in both directions. The second composite film is mounted on the carrier film. The packet of films is arranged between the two panes of glass so as to be wrinkle-free, pressed using pressure and heat and made into a composite with the panes of glass. A suitable carrier film and the use thereof for producing the laminated pane of glass are also disclosed.
