We add R4 insulation to provide a minimal level of protection; however a vapor barrier and additional insulation must be added to meet local requirements.
It is imperative that no sealants are applied to our units. Our VAULT® and CYCLONE® products, when used in combination with our RPH Exit SealsTM, form an ENGINEERED SYSTEM that guarantees the end user uninterrupted service for many years. This is precisely why we confidently provide a 20-year warranty to our customers.
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.
