Door Security 3
Door Security 3 : Security Weakness of Common Residential Door Types: Security tests by Consumer Reports Magazine in the 1990s found that many residential doors fail or delaminate when force is applied to them. Solid wood doors withstood more force than the very common metal skinned wood-edged doors used in newer construction. A broad range door manufacturer, Premdor (now Masonite) once stated in one of its 1990s brochures entitled "Premdor Entry Systems" page 6 that "The results of tests were overwhelming, Steel edged doors outperform wood-edged doors by a ratio of 7 to 1 When you consider the practically two-thirds of all illegal entries were made through doors. . . One hit of 100 lb[lbf] strike force broke the wood-edged stile and opened the door. To actually open the steel-edged door required 7 strikes of 100 lb pressure[force] ". Most door manufactures offer a number of different types of doors with varying levels of strength. Consumer Reports Magazine also reported in its test results that door frames often split with little force applied and lower quality deadbolts simply failed when force was applied to the door. The Chula Vista Residential Burglary Reduction Project which studied over 1,000 incidents; "We also learned what prevention techniques seemed to have little effect on whether a burglary would be successful. Methods found to have relatively low effectiveness included: sliding glass door braces, such as wooden dowels, as opposed to sliding door channel or pin locks; deadbolts installed in the front door only; and outdoor lights on dusk-to-dawn timers"
