Hurricane Resistant Building Materials Testing & Standards
The most common test for the hurricane market is the impact and cycling test, designed to simulate windborne debris striking a window or element of the building during a hurricane.
Hurricane Resistant Test & Standards
In hurricane-prone regions, architects, engineers, and owners face various design and safety challenges related to the building envelope and its ability to withstand severe storm and hurricane forced winds and water intrusion. The combination of intense wind, storm surge flooding, and heavy rainfall can lead to horrific damage to any structure.
Hurricanes and related test standards are based on wind speeds. The Saffir-Simpson Scale defines five categories of a hurricane based on sustained wind speeds.
Saffir-Simpson Hurricane Classifications
- Category One: 74-95 MPH – Very dangerous winds will produce some damage
- Category Two: 96-110 MPH – Extremely dangerous winds will cause extensive damage
- Category Three: 111-129 MPH – Devastating damage will occur
- Category Four: 130-156 MPH – Catastrophic damage will occur
- Category Five: Greater than 157 MPH – Catastrophic damage will occur
Hurricane Testing & Florida Building Codes
Manufacturers know the importance of their building products meeting code compliance to be used in hurricane-prone areas, including the High-Velocity Hurricane Zone (HVHZ). Hurricane codes are typically defined by the geographical location of the building, which can be defined by The American Society of Civil Engineered wind speed map – ASCE 7. Florida is the most prone market for hurricanes and has implemented some of the toughest hurricane codes in the world. Florida building codes must meet the requirements of Miami-Dade County or the state of Florida to receive either a Notice of Approval (NOA) or Florida Product Approval (FPA), respectively.
The Florida Building Codes (FBC) are administered by the Florida Building Commission. The FBC is based on the International Building Code (IBC), which is used throughout the United States. As a result of the destruction caused by Hurricane Andrew in 1992, the state of Florida designates various wind zones to mandate product approvals. The FBC created the High-Velocity Hurricane Zone (referenced above) and includes Miami-Dade and Broward counties with ultimate design wind speeds > 170 mph. Wind Zones 1, 2, and 3 are defined for ultimate wind speeds ranging from 130 mph up to 170 mph.

Properly testing hurricane proof building materials to make sure they meet the proper standards is crucial.
The most common test for the hurricane market is the impact and cycling test, designed to simulate windborne debris striking a window or element of the building during a hurricane. Providing protection from flying debris and breaching the building envelope is critical. If a structure’s envelope is breached, wind will enter the building, creating pressure changes that can lead to the destruction of both the contents of the building and the building structure itself. Additionally, a breached opening can allow water into the building causing water damage throughout.
Impact and cycling tests are designed to simulate the hurricane act of flying debris and the rapid increase and decrease in pressure.
The weakest links in a building envelope are windows, doors, and roofs. For windows and doors, the impact test consists of firing a 2x4 projectile at predetermined locations. The cycling portion of the test is conducted after the impact test with no penetrations and consists of 9,000 cycles of positive and negative pressures.
The Intertek team will work with your team to efficiently conduct tests and prepare the appropriate test reports you need. We offer all the required hurricane tests based on your project or product requirements, including but not limited to the following:
