Legacy and Historical Information

Please note that FEMA does not endorse, approve, certify, or recommend any contractors, individuals, firms, or products. Contractors, individuals, or firms, shall not state they are, or produce products that are "FEMA approved" or "FEMA certified."

Door Assemblies and Components

The following links are maintained by their respective organizations and provide lists and information on safe room door assemblies and components that have passed previous missile impact testing criteria. The UL site also lists required design pressures and test-rated pressures, while the Texas Tech University site notes “ICC 500 Pressures” when the listed component assembly has demonstrated compliance.

Depending on the year and expected application of the products listed, the current pressure and impact criteria may be different than at the time of testing, so these lists are intended to be used as a resource to provide a starting point on what door assemblies and components could be considered for safe room use.

Wall Sections That Passed Previous Missile Impact Test

The Texas Tech University National Wind Institute (NWI) provides reports on wall sections that passed previous missile impact testing standards, and more information on the testing protocol. The testing on these wall sections may or may not have been more stringent than current standards, and it is important to note that they may not necessarily pass current missile impact testing. View the results of the Construction Materials Threshold Testing Report.

Report information typically includes a description of the wall construction (e.g., stud wall with plywood and/or metal sheathing, stud wall with concrete infill, reinforced CMU wall, insulating concrete form [ICF] wall), cross-section illustration, test missile speed, and description of damage. The list is to be used merely as a resource of knowledge gained from past testing to determine which wall sections could be considered for use in a safe room application.
