Apparatus for edge mounting security window film in a window frame

A window security apparatus for resisting high tensile loads applied to a window film when said window film is adhered to a glass pane mounted in a window frame, comprising in combination;

• security window film adherable to said glass pane,
• an elongate tensile loading transfer member having first and second adjacent elongate load bearing flanges and corresponding first and second respective elongate bearing surfaces thereon,
• first and second elongate double sided foam adhesive tape strips mountable, on first sides of said adhesive tape strips, along respective said first and second bearing surfaces,
• said first adhesive tape strip mountable on its second side, opposite to said first side, to an edge of a sheet or said security window film having a thickness of at least 10 mil adhered to said glass window pane,
• said second adhesive tape strip mountable on its second side, opposite to said first side, to an edge of said window frame adjacent said edge of said sheet of said security window film,
• wherein, said first and second adhesive tape strips are adapted to bear approximately 225 lbs pet square inch in tension applied to said first and second adhesive tape strips and to said security window film when adhesively mounted to said tensile load transfer member by said first adhesive tape strip and to said window frame when mounted to said tensile load transfer member by said second adhesive tape strip,
• and wherein said second elongate load bearing flange is bent alone an edge thereof so as to form an adhesive tape strip receiving cavity for snugly receiving therein said second elongate double sided foam adhesive tape strip, said edge bent so as to be closely adjacent said window frame when said tensile load transfer member is mounted to said window frame,
• and wherein said tensile load transfer member is W-shaped in cross-section.
