The information below discusses wall sections that passed previous missile impact tests.
The link provided below to the Texas Tech University National Wind Institute (NWI) is for the website maintained by NWI containing the 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. 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.
Information on debris impact testing can be found at the Texas Tech University National Wind Institute (TTUNWI) website. Results from tested wall sections may be found in the Construction Materials Threshold Testing Report found on the TTUNWI website.
