Other than the inner foam, these doors have other insulating enhancements in the form of high efficiency sealing systems to further keep out sound and the elements.
Plus, although \"fire doors\" can be purchased, businesses still receive excellent protection against the spread of fire with steel security doors. Steel doors also provide increased energy efficiency, since they insulate the cold air from outside up to 4 times better than wooden doors.
The police and fire departments thought the door was a painted wooden one and attempted to break their way in. Upon realising it was a steel door security, they sent for additional assistance. After almost an hour using two determined workers with special tools the rescue team pried the steel framework apart enough to disengage the locks on this 30 year old steel door. The high security steel doors had done their job!
