Abstract
Bonded screens such as vehicle windscreens ( ) bonded to a supporting frame ( ) by homogeneous bonding material ( ) are released by firstly arranging energy delivery means ( ) adjacent the screen and subsequently transmitting energy from the delivery means through the screen thereby to effect release of the screen ( ) from the frame ( ) by either causing degradation of some of the homogeneous bonding material and/or cleavage or degradation of the screen material. The energy delivered may, for example, be ultrasonic or laser radiation, and is preferably arranged to be concentrated at a predetermined localized region to enhance the release mechanism.
