Abstract:
A method of releasing a vehicular window pane from a supporting frame to which the window pane is bonded by interposed homogeneous bonding material, the method comprising the steps of:(a) arranging a light energy delivery apparatus having an applicator head placed in contact with the window pane adjacent a peripheral edge of the window pane; and (b) transmitting light energy having a wavelength in the range from about 350 nm to 1000 nm from the applicator head of the light energy delivery apparatus through material comprising the window pane and causing thermal pyrolytic degradation of material comprising at least one of the homogeneous bonding material and the window pane, thereby to effect release of the window pane from the frame.
