If you’re following the 2018 IBC or an earlier version, utilize the ICC 2014 SAFE ROOM/STORM SHELTER code. For projects under the 2021 IBC Code, use the ICC 2020 code for safe rooms. These codes provide guidelines for constructing safe rooms and storm shelters to ensure occupant safety during severe weather. To ensure compliance, contact your local building code officials for information.
The size options for manufacturing CYCLONE® products vary depending on the specific product. We offer a range of sizes that have been thoroughly tested and meet our quality standards. The sizes must be within the range of the smallest and largest tested options to ensure compliance. We can provide guidance and assistance in choosing the appropriate size for your specific requirements.
