How Blast Resistant Doors and Windows Work – E-Library

xplosion. Usually, the doors are constructed of steel that is thick and feature to resist high the pound-force-psi (per sq inch) from blast events. The doors and windows can be classed based on the amount of psi they’re capable of resisting.

Doorways that are bullet-proof and windows safeguard visitors as well as workers in places that are prone to being attacked. The windows are employed for dangerous chemical handling in factories and production. They are not just a way to safeguard lives, but they also shield the company from injuries or negligent death lawsuits.

To function properly to be practical, bullet-proof doors and windows must come with an SDOF (single degree of freedom) system. The degree of freedom defines the entire parameters that affect a physical system’s state. An excellent example of SDOF can be windows and doors that are bullet proof windows, which can be rated at eight psi and five psi, in each case.

A window with a low pressure decreases the blast rating of the entire construction. A door that can withstand blasts has the same strength as the weakest part of it that is the SDOF. The materials used in the production of doorways that resist blasts and windows are based on the level of resistance. The most common types of materials include wood or aluminum, steel and concrete. kxjdglulnw.
