Resistance of Glass to Typical Forced Entry in Japan

Hirotsune Okubo

Test methods for typical forced entry in Japan and resistant properties with various glass glazing products were investigated. Resistance time and the noise level were measured for evaluation. Monolithic annealed glass, film-coated glass, insulating glass, and laminated annealed glass were used as specimens. Laminated annealed glass, especially having 0.03 to 0.09 inch-interlayer, showed high resistance compared with the other glazing products.
