A window or door has a glass pane (2). In order to secure the pane (2), e.g. against fall-out under impact load or against forced entry, an adhesive film (3) covers the pane (2) and overlaps the surrounding inside surface (4) of a frame (1). Clamping profile (5) is attached along the inside surface (4) of the frame (1) adjacent the pane (2) to clamp the overlapping edge (31) of the film (3) against the frame (1). The clamping profile (5) has a gasket (11) abutting against the film (3) on the pane (2). In order to secure against increased impact loads and hinder tearing of the film (3), the profile (5) has a curved portion (8) and the gasket (11) protrudes from the profile (5) so as to form a space (15) around the curved portion (8) and allow stretching movement of the film (3) around the curved portion (8) during an impact.
Apparatus for securing a pane of a window or door against impact comprising an adhesive film for covering the pane and overlapping a frame surrounding said pane and a clamping profile comprising a first elongate side portion attachable by fixing means therethrough to the surrounding frame to clamp the overlapping film, and a second elongate side portion having a gasket protruding therefrom for cushioning impact movement of the pane and film, wherein the first and second elongate side portions are substantially at right angles to each other and are connected by an elongate curved portion of the profile so as to provide substantially continuous support for the film from the first elongate side portion to the gasket during an impact on the pane and thereby minimise the risk of a tear of the film during impact, the outer surface of the curved portion of the profile having a radius of curvature from 4 mm to 15 mm.
