Abstract
Glazing panels such as vehicle glazing panels bonded to a supporting frame are released by firstly arranging light energy delivery means adjacent the panel and subsequently transmitting light energy from the delivery means through the panel thereby to effect release of the panel from the frame. The light may be pulsed according to a predetermined regime and may be delivered by a discharge lamp having rapidly attenuating intensity. The mechanism of panel release may be by thermal degradation of the bonding material, cleavage of material at a surface of, or within the body of the panel, or a combination of such mechanisms.
