The information below discusses 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.
- Information on debris impact testing, including reports on doors and components that have passed missile impact testing, can be found at the Texas Tech University National Wind Institute website.
- After linking to the UL Online Certification Directory, enter ‘zhla’ in the UL Category field and ‘ICC 500’ in the Keyword field for safe room-tested products.
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."
