Insulgard Security Products manufactures a line of aluminum window and door systems meeting ICC500-2020, ICC500-2023, and FEMA361-2021 requirements for use in tornado and hurricane storm shelters across the country, including 250mph wind zones.
Our STORMDEFEND impact-resistant windows and doors have been extensively tested at Underwriters Laboratory, including:
- Pressure testing exceeding 360psi
- Debris impacting testing of a 15# 2×4 at 100mph

Cities and states in 250mph wind zones that have adopted the International Building Code® from 2015 or later require all new schools and critical emergency facilities to construct a tornado shelter that meets ICC500 requirements.
