Jamb/Stud Wall Security

Source

This paper deals with a single specific building security problem. It is the researchers intent to point out the inherent weakness of “jamb/stud” wall construction adjacent to door jambs, specifically relating to the problem of mechanical “spreading” as a means to gain illegal entry.

Comparative data and comments were compiled as a result of testing based on ASTM Tests for Security of Swinging Door Assemblies (F476 - 76) 2 by 4 wall construction versus a modified 2 by 4 wall condition. The conclusion drawn points to sufficiently increased resistance to illegal entry by minor modification of the common wall structure adjacent to door jambs.
