For higher volumes of http://www.safesgun.net heat-sensitive materials, a modular room-sized vault is much more economical than purchasing and storing copious luminosity rated safes. Customarily these room-sized vaults are utilized by corporations, government agencies and off-site storage service firms. Fireproof vaults are rated up to Class 125-4 Last Minute for considerable data storage applications. These vaults utilize ceramic fiber, a eminent temperature industrial insulating material, as the core of their modular panel system. All components of the vault, not just the walls and roof panels, must be Class 125 rated to achieve that overall rating for the vault. This includes the door assembly (a double door is needed since there is no exceptional Class 125 vault door available), cable penetrations, coolant line penetrations (for split HVAC systems), and air duct penetrations.
There are also Class 150 applications (such as microfilm) and Class 350 vaults for protecting valuable wafer-thin documents. Like the data-rated (Class 125) structures, these vault systems employ ceramic fiber insulation and components rated to meet or exceed the required equivalent of protection.
