Evaluating the Intrusion Resistance of Installed Motor Vehicle Glazing

Intrusion resistant glazing increases the time and effort required to gain unauthorized entry to a motor vehicle. This paper presents the results from a series of tests designed to measure the performance of laminated intrusion resistant glazings as installed. These tests were conducted as part of a study to evaluate the performance of different polyvinyl butyral (PVB) interlayer thicknesses and adhesions for penetration resistance. Readers of this paper should gain a broad understanding of the performance of these glazings and their level of resistance.
